The Testo 176-H1 and 176-H2 compact temperature and humidity data loggers are designed with two connections so that the remote probes can be positioned within the room or controlled space according to individual requirements. These instruments can operate over a wide temperature range (- 20 to + 70 oC), offer good accuracies for both humidity & temperatures measurement parameters, and have a built in memory for 2 million values. The H1 version has a backlit display, the H2 version comes without a display.
Features
