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
