HDH-M-RH transmitters with a Modbus communication are designed for detecting and controlling carbon dioxide concentration, temperature and humidity in room spaces. ABCLogic™ self-calibration method eliminates the possible long term drift. The controller settings, modbus settings and options' limits can be changed by using the ML-SER tool.
