Infrared gas analyzers

Infrared gas analyzers

[ Printer-friendly version ][ Send to friend ]

The non dispersive infrared ZRJ, ZKJ, ZRE and the portable ZSV are intended for the continuous measurement of the concentrations of carbon monoxide and carbon dioxide (CO and CO2), sulfur dioxide (SO2), nitrogen oxides (NOx), methane (CH4) and oxygen (oxide of zirconium, electrochemical or paramagnétique) in the gas emissions of the fixed sources of pollution (boilers, ovens...).
They allow the measurement from 1 to 5 gases. The measurement system in simple or double beam and unique source gets to the user a maintenance of the easiest and assures a very good precision and a very big stability of the measure. The wide back-lit screen allows the display of the measures and the access the various parameters for configuration and maintenance. They possess very numerous functions: automatic calibration for  zero and span, alarms, automatic change of range, auto-diagnoses, correction by the dry oxygen, a digital connection with the protocol Modbus.

ZSV portable type
