MadgeTech

MadgeTech specialises in dataloggers, and the range here covers environmental, current and voltage loggers plus chart recorders.

Logging interval, memory depth and battery life together decide how long an unattended deployment can run, and that is usually the specification that matters rather than accuracy. For validation and cold chain work, confirm the unit produces a tamper-evident record and that its report output satisfies your auditor, since that is far easier to establish before purchase than after.
