RKI Instruments Introduces PPM Methane Range for the M2S Fixed Monitors

Posted by

RKI is now offering our Model M2A transmitter with a PPM range for methane detection. The M2A can monitor for 0 to 9,000 ppm methane with a resolution of 20 ppm.


This additional range means the M2A has the ability to monitor in the PPM, % LEL, or
% volume ranges for methane. The M2A PPM Methane transmitter is now available using the order information below.

To confirm if the ppm methane M2A is suitable for a given situation, please discuss your application with TG Technical Services at 816-524-8100
