RKI 72-2120-301 Digester gas monitor, 100% volume CH4 / 25% volume O2 / 1,000 ppm H2S

Description

The RKI 72-2120-301 Digester Gas Monitor checks for gases on a cyclical basis and is designed to handle these gases with no damage to the sampling system or sensors. The sample is filtered through a series of dirt, dust and moisture stopping filters, and these filters are automatically blown back and cleaned out with fresh air at the end of each cycle. Measurement time is just 4 minutes, taken at periodic cycles, while the cycle time is selectable, with settings for 1 hour, 4 hours, 8 hours, 24 hours or 7 days. After each cycle, the sensors and sampling system are flushed with fresh air to minimize corrosion caused by high H2S content. The system is fault tolerant, minimizing the possibility of expensive repairs or downtime. System integrity is maintained at all times using a flow fail monitoring device which provides a fail alarm and relay if there is ever a problem with the flow system, such as a blockage, or if the air aspirator compressed air supply is removed or interrupted.
