RKI SD-705RL Gas Detector

Feature & Principle

It is RKI SD-705 series non-dispersive infrared combustible gas detector. Based on NDIR infrared absorption principle, it detects methane and hydrocarbon gas concentration. Diffusion sampling structure, built-in alarm relay contacts. It converts gas concentration into 4-20mA analog signal to DCS or gas alarm controller. Automatic optical fault diagnosis, anti-poisoning design, suitable for long-term stable operation in oil and chemical hazardous areas. Magnetic adjustment simplifies field calibration without opening the housing.
