THE2572

The Testo 175/1476 series of products cover all potential datalogging applications likely to arise in laboratory environment. All 175/176 dataloggers run on conventional batteries, have a high memory capacity combnined with a USB and an SD card interface which makes readout of the data fast and easy. Both series offer temperature only or combined temperature/humidity dataloggers.

1 to 4 internal and external channels
NTC, TC (Types T and K) and Pt100 sensor options
Capacitive humidity sensor
Parallel monitoring option
Metal housing and higher levels of accuracy on the 176 series
Upto 2 million measurements on internal memory
