Reccomended temperature monitoring?

There is a standard for temperature calibration... should be to UKAS ISO/IEC 17025. Quite a few accredited centres in the UK with fast turnaround.

Where do you get that from? If I search "calibration" or "UKAS" I can find no mention in the PSS documentation?

You can adjust the calibration yourself.

Calibration certs have to be UKAS ISO standard these days... and those monitors don't appear to have the ability to calibrate adjust.

I just worry that one day I'll come in on Monday, everything will be warm and all I can say is that it was ok on Saturday morning and everything ends up in the bin. My thoughts with the data logger as back up was I could then go and check how long and how warm the contents had become, before speaking to the manufacturer.

Thanks. I've bought some of these, as recommended by a vet friend

https://www.amazon.co.uk/gp/product/B08Y8XHNL8/ref=ppx_od_dt_b_asin_title_s00?ie=UTF8&th=1

£14.50 each and can calibrate ourselves. I'll see how we get on and how well they connect via the Bluetooth and wifi.

We use a load of these... https://www.loggershop.co.uk/product/rtr501b-wireless-temperature-data-logger/ which take readings every 5 minutes, cloud archives temperature reports which you can print out weekly, emails and stores temperature variance alerts and are reasonably priced for annual calibration certificates. Company has been very helpful with set up as well.

main issue is fridges being opened and the air temperature rising for a short period (and this being logged on a data logger) whereas the actual fridge contents won't have warmed up. You can get thermometers designed to avoid this as the probe is in a pot of liquid so models more the reaction of a vaccine eg vial https://www.thermometersdirect.co.uk/eti-thermaguard-pharm-vaccine-thermometer.html (or put the external probe of a normal digital thermometer in an small bottle of water/glycol

That's what I would advise.

A little notebook will cost you about a pound and your pen will probably be free.

From the standards manual

[quote]There must be proper monitoring and recording of maximum and minimum temperatures wherever medicines are stored, and where temperatures have been recorded outside the appropriate ranges, there must be evidence of an action plan to remedy such deviations, and to deal with affected medicines. Consideration should be given to the use of alarms to indicate when temperatures stray out of set parameters.
Data loggers and maximum/minimum thermometers will provide constant monitoring. However, for those without an alarm to warn of temperature deviations, and for maximum/minimum thermometers, checks are required to be made daily and assessors will ask to see written records, produced on a weekly basis, showing the results for the week.
Ideally temperature sensitive medicines should only be taken out in vehicles on a “by use” basis, but whether being stored or transported, measures should be taken to ensure that products remain within the temperature range specified on their SPC e.g. by use of a cool box or refrigerated unit. The suitability of such measures should be demonstrated.[/quote]

I read that as "you don't have to have a data logger, but if you do, you must download everything weekly"

Maybe we need to go back to writing it down in a book, daily.

Our last VMD inspection favoured Bluetooth or WiFi loggers. I have normal ones so I am unsure how these are reset to stop the warning light on the device or whether you just get a notification.
