Next month, TechNet launches a new area for members to review cold chain equipment. The 'Reviews' area will list all PQS-prequalified devices and equipment, arranged into the following PQS categories:

Cold rooms and freezer rooms (E001)

Refrigerators and freezers (E003)

Insulated containers and accessories (E004, E005)

Temperature monitoring devices (E006)

Injection devices for immunization (E008)

Waste management equipment (E010)

Therapeutic injection devices (E013)

Members will be able to read and comment on the reviews of other members, and also submit their own. Reviews can be long or short, positive or negative, comprehensive in scope or simply anecdotal, and can be supported with photos, videos, PDFs, or other relevant material.

The first category that will be launched is 'Refrigerators and freezers', with the others coming shortly after. We hope the new area will encourage lively debate and valuable information-sharing of field experiences. If you would like to know more about the new area, please contact the moderator.

You can now share your equipment feedback on TechNet-21 without having to give your name. When submitting a cold chain equipment review, be sure to check "Do NOT display my name with this review". Once the review has been submitted and approved, your name and profile picture will not be displayed - instead, the author of the review will be listed as "Anonymous user".Hopefully, this new feature will encourage more people to share their experiences and feedback on cold chain equipment. The primary goal isto foster lively debate and valuable information-sharing of field experiences, so if you have experience of any PQS-prequalified device that you would like to contribute - anonymously or not -please take some time to share your thoughts in the Reviews area today.

On a related note, we are considering widening the scope of the Reviews area to include non-PQS prequalified devices. Much of the cold chain equipment currently being used in immunization programmes does not have PQS-prequalification (I wonder what the percentage might be?), and an argument can be made that Technet ought to include these devices irrespective of WHO prequalification. What do other members think?

Thanks for this, Pierre. I'm glad you find the new area of use. At present, the review categories are based on the WHO PQS categories (only prequalified devices are currently listed on TechNet). We have devices listed in E001, EOO3 & E006 at present, but we will be adding the rest very soon. Recategorising as you suggest does make sense, although I would like to wait until the new site is little older, and more feedback has been received, before changing things.

You make some very good points from c) to g). I will leave it to more knowledgeable members of the TechNet community to respond to these.

Hi Dan,

Thanks for bringing more devices for cold chain practitioners. We all lack access to good information and you are solving part of the problem. Here I share my experience in cold/frozen chain from Canada, Tajikistan, Kyrgyzstan, Kazakhstan, Azerbaijan, Thailand, Viet Nam, Mauritius, etc. in vaccines, SLD TB, blood samples, and serums, etc.

---

a) It would be very helpful you change the categories into the followings :

1/ devices for central warehouses (network of devices)

2/ devices for local storerooms and/or fridges/freezers

3/ devices for transportation

It will help tremendously practitioners and prevent poorly informed purchase. 3/ cannot use for 2/ and 1/ and vice-versa.

---

b) Up to you to have sub categories within these umbrella categories.

Since most of them are with USB plug, it should be told whether they require a software. A software is not too be promoted since very complicated for most of the staff using the devices.

---

c) What type of devices.

I believe that reusable devices should be promoted, since budgets are very low.

And it helps standardization/uniformization over time

---

d) Dial thermometer should be phased out since they don't record and don't alarm. In 2014, there is so many places where people still don't get it that temperature should be monitored 24/7 and NOT once a day, forgetting the 23 other hours. It will be very bad to still promote such poor practice

---

e) I am very very surprise that you don't promote devices with probes that would enable temperature recording for both freezer and fridge (as it happens in country when budget is so low that they use kitchen type fridges) - 2 in 1 type. This will help standardization and user-friendly, and reduce cost.

See: http://www.thomassci.com/instruments/digital-thermometers/_/thomas-high-accuracy-thermometer http://www.control3.com/4241p.htm

New high-accuracy dual thermometers read to 0.01 degrees while monitoring temperatures in refrigerator and freezer simultaneously or two refrigerator locations. Its temperature-buffered bottle sensor insulates and eliminates rapid temperature changes when refrigerator door is opened. A patented unit fulfills all CDC thermometer and vaccine thermometer requirements. They can also be used in water baths, heating blocks, and incubators.

•Triple display simultaneously shows minimum/maximum and current temperatures

•Minimum/maximum monitors readings for any time period and displays the exact time and date when the min/max temperature occurred for both thermometers

•Alarm provides two visual and two audio alerts when temperature rises above or falls below high and low set points

•Unit displays the exact time and date when dual thermometer alarms are triggered

•Alarms are programmable in 0.01° increments

•Visual and audible alarms signal continuously (for days) even if temperature returns to non-alarm range

•Ten-foot micro-cable permits refrigerator doors to close on it

•Range is –58 to 158°F and –50 to 70°C with a resolution of 0.01° and accuracy of ±0.3°C

•Probe is sealed in a miniature bottle (1 x 2-1/2 inches) filled with non-toxic glycol

•Eliminates concerns about incidental contact with food or drinking water

•High-impact, chemical-resistant ABS plastic case is: 2-3/4 x 4-1/4 x 3/4 inches. Weight is 5 ounces

•Stand, Velcro™, magnetic strips, and wall mount allow placing thermometer and bottle sensor anywhere

To assure accuracy, an individually serial-numbered Traceable® Certificate is provided by an ISO 17025 calibration laboratory accredited by A2LA. It indicates traceability to standards provided by NIST (National Institute of Standards and Technology).

---

f) It will be even better to have 3-in-1 that would include a room temperature monitoring.

I was not able to find one.

---

g) why don't you propose for storeroom monitoring a temperature/humidity recording device ?

As per medicine's monograph, humidity MUST be in control as well.

I have found this one 2-in-1 :

http://www.thomassci.com/instruments/hygrometers/_/thomas-traceable-remote-alarm-rhtemperature-monitor?q=1235c96

http://www.control3.com/4154p.htm

Relative humidity range is 20 to 99%

Resolution is 1% RH

Accuracy is ±5% RH mid-range

Temperature range is -58 to 158°F and -50 to 70°C

Resolution is 0.1°

Accuracy is ±1°C

Battery: AAA (1.5V DC)

Features include minimum/maximum memory and RH and temperature alarm. Unit measures 4 1/4” x 2 3/4” x 3/4” and weighs 4 ounces. Monitors are provided with an individually serial numbered Traceable® certificate from an ISO 17025 calibration laboratory accredited by A2LA. Certificate indicates traceability to standards provided by NIST. 

 

Thanks and best regards,

UPDATE: All PQS-prequalified temperature monitoring devices have now been added to the Reviews area on TechNet-21. We encourage all members to share their experiences (both positive and negative) of these devices by submitting their own reviews of temperature monitoring equipment they have used. We have already seen some interesting reviews and responses to equipment in the Refrigerators and freezers category; hopefully this will continue with temperature monitoring devices.

The devices are organized into the following categories. The number of devices currently in each category is shown in (brackets):

Central temperature monitoring systems (2)

Dial thermometers (0)

Electronic freeze indicators (3)

20 day electronic shipping indicators (5)

30-day Electronic temperature loggers (30DTR) (3)

User programmable temperature data loggers (6)

Chemical temperature indicators (2)

Note that you need to be signed in to read equipment reviews and post your own. All reviews and responses are reviewed by the moderator prior to publication. This can take up to 24 hours, but usually takes much less.

TechNet-21 launched the Reviews area last month. The intention behind it is to enable immunization professionals to share their views and experiences on immunization equipment that has been prequalified by WHO. In the new area, members can browse through equipment reviews, and also submit reviews on equipment they have used. This exchange encourages lively debate and valuable information-sharing of field experiences. 

Currently, there are two categories of PQS equipment that can be reviewed:

Refrigerators and freezers (E003)

Temperature monitoring devices (E006)

Equipment in other PQS categories will be added in the coming weeks.

The 'Reviews' area is now live, and can be accessed by clicking 'Reviews' in the menu bar at the top of the page. (Note that you need to be signed in to TechNet to read and submit reviews. If you have trouble signing in, please contact the TechNet moderator.) At present, members can only review products in the Refrigerators and Freezers PQS E003 category. This will shortly be expanded to include products in every other PQS category. Please take a look around, read the reviews, and submit your own. Let us know what you think - can the system be improved? Are there any bugs?
