EmbrientModel GMS-5002 -Gas Mixing System

SHARE
The GMS-5002 is a flow-through O2 sensor providing fast oxygen readings from 0% to 25%. Used in tandem with our Dual Flow Meter, it is ideal for accurately mixing custom O2 and CO2 concentrations for hypoxic and culture conditions or where special pre-mixed gases are expensive or unavailable.

The GMS-5002’s oxygen sensor, measures ambient oxygen partial pressure (pO2). Internal pressure, temperature & humidity sensors enable the GMS-5002 to integrate these additional sensor readings and convert the pO2 reading to an oxygen percentage (%O2) as seen on the display.

The integrated solid-state sensors does not need replacement or re-calibration like conventional electro-chemical or galvanic sensors. The readings are factory calibrated to compensate for ambient temperature, pressure and humidity, enabling accurate operation over a wide environmental range. The system is easy to operate, very stable and robust, does not contain hazardous materials and has negligible cross sensitivity to other gases (e.g. CO2 and N2).
