TRED30 Vaccine Monitoring Kit – VFC Compliant, Fridge/Freezer Calibrated Temperature Logger (Requires LTI-USB Docking Station, Sold Separately)

This is VFC compliant. I considered getting the one that's slightly cheaper and does not come with a probe but felt that it would be better to have one calibrated with the specific probe. Not sure it really makes a difference but that was my thinking.

Fantastic item, but should come with instructions. Difficult To get going but once it is it works well!

Very Pleased with this purchase

I have bought a lot of different temp loggers from LogTag (Microdaq) and others over the years. I routinely get 4+ years of service on LogTag TREX-8 with external probe taking 10 minute readings. And they always came calibrated pretty much dead on to reference thermometers and never drifted much over their lifetime, staying within 1F. I thought I would upgrade to model TRED30-16CP that gave a realtime readout and an audible alarm. Said on the product flyer that calibration software would be provided for free to calibration companies and I need yearly calibration so I bought some. Both units as received read more than 3 degrees off from two recently calibrated reference thermometers, using 2 different brand new LogTag standard external probes. I asked my calibration service to request the software to calibrate the units and they were denied. LogTag lied in the product flyer and will only calibrate these themselves, using only a single point calibration for $59. I am mainly pissed that they units were so far off as recieved new. The other two brands of temp loggers I use are all a bit more expensive, but both come with free software built into the graphing and download program that allows for user calibration. LogTag not providing this option is a huge negative and I would use the standard practice to double check your units against reference thermometers after you get them to verify accuracy.
