S128 Methane Analyzer 5000ppm

Qubit's S128 Methane Analyzer uses state of the art Non-Dispersive Infrared Technology (NDIR) to measure Methane Levels in a flowing gas at two ranges 0-1250ppm and 0-5000ppm. The instrument is equipped with a Digital Display that provides a measure of the methane concentration in units of ppm. In addition, an Analog Output Signal (0-5VDC) is provided for Data Logging by a computer with our Optional Software and Data Interface.

The S128 Methane Analyzer is a Flow through Gas Analyzer therefore gas should be supplied under pressure at flow rates not to exceed 650ml/min. An optional built-in Gas Pump may be provided with the S128-P unit for easy delivery of the gas to the sensor. Qubit' S128 Methane Analyzer may be used in the field with Optional Battery Pack (A249).
