Hydrogen Sulfide Detector-Transmitter
- Stable long-life electrochemical cell
- Typical range 0...100 ppm or 0...2000 ppm
- Resolution 0,1 / 2 ppm H2S
- Attached or remote sensor option
- 2 × 4-20 mA / 0-10 V, RS485
- Two SPST relays
Hydrogen Sulfide detector-transmitter E2638R-H2S is a member of new PluraSens® family of multifunctional measurement instruments.
Applications include sewerage systems, labs, industrial premises and other areas, where potentially toxic concentration of hydrogen sulfide can accumulate.
The instrument utilises novel fully calibrated and temperature compensated gas sensor with excellent repeatability, stability and long lifetime.
Two analog outputs and RS485 digital interface with industry standard Modbus RTU protocol can be used to connect the device to safety or building automation systems.
Two relays with closing contact may be used for remote signaling or ventilation control. The default alarm set-points are typically at 10 ppm and at 20 ppm. The flashing LEDs and an internal buzzer give alarms as well at two set-points.
