Air Aspirator Gas Monitor

Harsh Environment Sampling System

DigesterSingle or dual sensor system is designed to monitor gas atmospheres from extreme conditions with either temperature, moisture, or pressure challenges. A powerful air aspirator can pull a sample from up to 100 feet away. The filtered and conditioned sample gas is then passed across one or two different detectors. Each detector shares a common calibration and compressed air inlet for aspirated flow. This system is fault tolerant removing the need for expensive downtime and maintenance. The sample is diluted with air after the gas sensor and then returned to a common exhaust reducing the danger of potential hazardous gases entering a safe work space.

Single / Dual Sensor Air Aspirator

Digester Gas Monitor

Harsh Environment Sampling System

Digester Gas MonitorGas from waste digesters contains high levels of methane, CO2, and H2S, with little to no oxygen present. The RKI gas monitor checks for all these gases on a cyclic basis. A powerful air aspirator pulls a sample from up to 100 feet away. Since digester gas contains high humidity and high H2S, both of which can cause damage to sampling systems, the RKI Digester Gas Monitor is designed to handle these 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.
