HDH-Series

Room CO2 Transmitter HDH

HDH transmitters are designed for measuring and controlling carbon dioxide concentration, temperature and humidity in room spaces. The measurement values scroll on the N model display. The wanted value can be locked to view continuously. The self-calibration method eliminates the possible long term drift. The controller settings and options' limits can be changed by using the ML-SER tool.
