AMS 3186 Gas analyzer

The trace oxygen analyser AMS 3186 operates on base of an electrochemical sensor. The trace oxygen analyser AMS 3186 is a micro-processor controlled analyser for the highly accurate measurement of lowest oxygen traces.

Changes in concentrations of < 0,1 ppm of oxygen with a resolution of 0,01 ppm can be measured. The available housings are designed for use in general applications. The lowest oxygen measuring range is 0 … 1 ppm.

Available options:
bypass and purge valve, manual
2 free adjustable messages
electronically flow control
electrical/pneumatic gas pump
manual 5 way valve
particle filter 2 µm
auto-calibration, also with remote control
automatic purge of the sensor
pressure reducer
thermostatted measuring cell
different housings
