Fixed location detectors for permanent process or wall installations.
A241
The KWJ 241 Methane BIOGAS Monitoring System monitors landfill methane. Using the NDIR method to digitally display CH4 concentrations from 0-100%, this instrument provides system-wide reporting in multiple locations and may be designed in wireless configurations. Each instrument is automatically maintained at a preset temperature by internal heaters and temperature control systems. A […]
A322
The KWJ Model 322 Oxygen (O2) BIOGAS Monitoring System is a 115 VAC oxygen analyzer designed to monitor digester gas for oxygen. It indicates the concentration over the range 0-25% and provides a 4-20mA output signal proportional to the percent oxygen. The instrument continuously monitors a sample gas forced through the instrument under its own […]
A345
The KWJ 345 BIOGAS ‘FiveElevations’ Landfill Monitor is a BIOGAS detection system for CO2 in a range of 0-60% and CH4 in a range of 0-60% measured through five different elevations in a well or sample site. This unique system utilizes solenoid valves to separate gas samples drawn at each inlet, each equipped with […]
A358
The KWJ 358 BIOGAS Hydrogen Sulfide Data Logger and Monitor is a weather resistant instrument using sample draw and electrochemical sensing to monitor air samples. A 4-20mA output signal is sent to the data logger for later download. Built for rugged operational conditions, the Model 358 uses a digital LCD display, trouble […]
A383
The KWJ 383 Methane and Oxygen Digester BIOGAS Monitor: O2 and CH4 are measured with one monitoring system using only one sample stream. Both gases are continuously monitored and displayed using infrared sensing for methane and amperometric electrochemical sensing for oxygen. A sample draw pump and 4-20mA outputs are housed in two separate […]
A401
The KWJ 401 BIOGAS Three Gas Analyzer is a wall mount gas analyzer for testing BIOGAS streams prior to release to downstream users. Methane in a range of 0-100%, CO2 in a range of 0-5%, and H2S in a range of 0-25ppm are measured in a diluted sample stream and displayed on individual digital […]
