Explosion proof housing

Remote Transmitters for Oxygen and Toxic GasesThe EC 30 is an advanced transmitter for the detection of toxic gases and oxygen levels. This smart area monitor has an aluminum explosion proof housing with a stainless steel sensor cover that makes the EC 30 series suitable for the harshest environments.

Simple and effective

Once you power up the units, they will accurately display values on the large LCD and transmit a linear 4-20 mA signal to any GfG controller. AutoCal® automatic calibration and maintenance is done effortlessly through push buttons or via a remote digital control connection. Smart sensors allow the user to easily change ranges or gas types in the field without the need for additional programming. The EC 36 is equipped with onboard relays for two alarm points and one sensor fault for local connection and activation or deactivation of external devices like alarms, fans, auto dialers, etc.

Digital display / control connection

The digital connection allows display of readings, non-intrusive maintenance, and AutoCal^® calibration activation to be done locally or from a distance.
