Using a NDIR sensor for measuring CO2 concentrations and utilizing ABC (Automatic Baseline Correction) algorithm, they offer excellent long term stability & accuracy. Available with active temperature and RH outputs, as well as other passive outputs and user interfaces. A unique feature of this sensor automatically detects what the controller input is set to, 4-20mA or 0-10Vdc. This removes the requirement for output jumpers that can be inadvertently set incorrectly.
