Qubit S129 Methane Analyzer is a non-dispersive infrared (NDIR) gas analyzer that measures methane levels in a flowing gas at 0-500ppm range. The instrument is equipped with a digital display and an analog output signal (0 – 5 V) for data logging data by a computer with our optional software and data interface.
The S129 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 ( S129-P) for easy delivery of the gas to the sensor. Additionally, a mass flow monitor may also be included for measurements of flow rate through the sample chamber (S129-PF). The S129 Methane analyzer is housed in a weather proof case with temperature control for enhanced stability of the signal and is ideally suited for both lab and field research (with an optional battery pack).
