Tenmars TM-305U Temperature and Humidity USB Datalogger

Tenmars TM-305U Temperature and Humidity USB Datalogger

The Tenmars TM-305U is a compact 2-channel datalogger that measures and records temperature and relative humidity. It uses an NTC temperature sensor and a capacitive humidity sensor, covering -40 to +85.0 °C (-40 to +185.0 °F) and 1 to 99 %RH, with readings in °C or °F.

The recorded data is transferred directly to a computer through a USB cable, so no docking station is required. The USB interface is used both for setting up the logger and for downloading the data, and the full memory of 50,000 records is downloaded in less than 10 seconds.

The housing is waterproof to IP 54, and a Hi-Low alarm can be set up to indicate readings outside the chosen limits.
