For vaccines, there are kits with a glycol bottle probe and a calibration certificate, a Wi-Fi cloud version that meets 21 CFR, and USB loggers with a display showing the maximum, minimum and last reading. Compact, rugged loggers with a capsule that protects against moisture and solvents travel with samples, and GSM loggers send readings and location while in transit.

There are also packs of preconfigured loggers with alarms for refrigerated products, and some models calculate MKT with software that complies with FDA 21 CFR Part 11.
