Low Cost Transmitter
Datasheet • CO Manual • H2S Manual
The RKI low cost CO/H2S transmitter is a highly reliable and very cost effective basic 4-20 mA transmitter for the detection of carbon monoxide and hydrogen sulfide. The electronics are protected inside a plastic enclosure to avoid damage from mechanical abuse, water, dust or corrosion. Sensors for H2S and CO are long life and typically last 2 - 3 years.
The transmitter operates from 24 VDC (11VDC to 30 VDC), and provides a 4-20 mA signal which can be connected to a wide variety of controllers. The low cost CO/H2S can be used either indoors or in semi-enclosed areas.
The only tools required to calibrate the low cost CO/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.

Made in the USA
RKI is proud to introduce and 
announce the release of our new product, the EAGLE 2. Building on the strong success of the popular EAGLE series.
The 2010 Winter Olympics Cauldron was built with a fixed gas detection system using RKI’s products. A Beacon 410 controller and four Direct Connect LEL sensors were installed inside the arms of the
outdoor cauldron.
RKI’s H2 sensors were also used inside the fuel cell buses that transported athletes and spectators, and in the garages and terminals where the buses were used
The GD-70D is a compact transmitter for detection of toxic gases, oxygen, or combustible gases and vapors. This new smart gas detection transmitter series sets a new standard for performance, flexibility, and versatility. The GD-70D sample-draw transmitter offers an array of sensor technologies unmatched in the industry, including unique offerings, such as our hydrogen-specific ppm and LEL versions.
