3503-200 EC 35 Fixed Gas Transmitter, Hydrogen Sulfide (H2S), Display by GfG
Remote Transmitters for Oxygen and Toxic Gases
The 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 digital remote control connection. Smart sensors allow the user to easily change ranges or gas types in the field without a 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.
Features
- Robust industrial design
- Fully-automatic one button calibration adjustment
