Tinytag Ultra 2


  • Indoor

Indoor temperature and relative humidity data logger with built-in sensors

-25 to +85°C/0 to 95% RH

The TGU-4500 monitors temperatures ranging from -25 to +85°C, and relative humidity from 0 to 95% using built-in sensors. It is primarily suited to indoor monitoring. However it can be used outdoors with appropriate protection such a Stevenson Screen. Like the rest of the Ultra 2 range, this accurate and reliable unit has a lightweight, splash-proof design.

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