Additional information

The NB3 fixed gas transmitter allows the monitoring of a wide range of gases. It has a range of 88 sensors for various toxic, refrigerant, explosive, and volatile organic gases in safe areas. The 4-20 mA analogue output makes it suitable for different applications.

The NB3 gas detector is designed for maximum ease of use, with interchangeable, factory pre-calibrated sensors. The RS485 output (DEGA protocol) allows for substantial savings in wiring, thus reducing installation costs. With or without display, this detector can also be equipped with an internal 3-relay card and a Modbus card (optional).
