RKI GX-2003 Multi-Gas Monitor LEL Sensor

RKI GX-2003 Multi-Gas Monitor LEL Sensor monitors combustible (LEL) levels

Replacement combustible gas (LEL) sensor for RKI GX-2003 multi-gas monitor.

The % LEL sensor detects combustible gas in the % LEL range. It uses a catalytic element for detection. The reaction of gas with oxygen on the catalyst causes a change in the resistance of the element which affects the current flowing through it. The current is amplified by the GX-2003's circuitry, converted to a measurement of combustible gas concentration, and displayed on the LCD.
