RKI low cost H2S transmitter is a highly reliable and very cost effective basic 4-20 mA transmitter for the detection of hydrogen sulfide. The electronics are protected inside a plastic enclosure to avoid damage from mechanical abuse, water, dust or corrosion. Sensors for H2S are long life and typically last 2 – 3 years. The low cost H2S can be used either indoors or in semi-enclosed areas.

The only tools required to calibrate the low cost H2S transmitter are a voltmeter, screwdriver, and calibration gas. The zero and calibration functions are performed by adjusting potentiometers on the amplifier board. The amplifier board has test jacks for the connection of a voltmeter for calibration purposes, and the sensor response is viewed on the voltmeter as a 100mV to 500mV signal. Field calibration can be performed easily and quickly by one person.
