65-2424RK M-Series Hydrogen Sulfide (H2S) Sensor/Transmitter in Plastic Enclosure (Not Explosion Proof) by RKI Instruments

Some gas monitoring requirements are basic but important. The RKI M-Series transmitter is a highly reliable and very cost-effective 4-20 mA transmitter for the detection of carbon monoxide and hydrogen sulfide. This transmitter operates from a 24 VDC (11 VDC to 30 VDC) power source and provides a 420 mA output signal, which can be connected to a wide variety of RKI or third party controllers. The M-Series transmitters are built for use in either indoor or semienclosed areas.

The electronics are protected inside a plastic enclosure to avoid damage from mechanical abuse, water, dust or corrosion. Sensors for the M-Series have a long life-span that typically last two to three years.

Field calibrations are very basic and can be completed by a single person. The zero and calibration functions for the MSeries are performed by simply adjusting potentiometers on the amplifier board. The amplifier board is equipped with easily accessible test jacks for the connection of a voltmeter. The voltmeter is used to view sensor response while the calibration gas is being applied and the potentiometers are adjusted with a screwdriver.
