Rugged, waterproof temperature and relative humidity logger with built-in sensors

-25 to +85°C/0 to 100% RH

The TGP-4500 monitors temperatures from -25 to +85°C, and relative humidity from 0 to 100% using built-in sensors. The coated RH sensor offers good resistance to moisture and condensation, and like the rest of the Plus 2 range, this accurate and reliable unit is ideal for monitoring in outdoor and industrial applications.

This logger requires Tinytag Explorer software and a USB cable (CAB-0007-USB).
