AMS 3195

For the measurement of traces of oxygen in inert gases with impurities of hydrogen, carbon monoxide and / or hydrocarbons AMS offers the analyser AMS 3195 with catalytic inactive ZrO2 sensor. Since the catalytic inactive ZrO2 sensor is regulated at an operating temperature of 650 °C the temperature of the process gas is not of significance. The trace oxygen analyser AMS 3195 is highly accurate. In the range of 0 … 10 PPM even changes in the oxygen concentration of 0,05 PPM are traceable.

Like all microprocessor AMS analysers the AMS 3195 is controlled by software. Three touch keys on the analyser front allow direct access to all analyser functions. All system parameter are continuously monitored by the analyser electronics. As an option, the trace oxygen analyser AMS 3195 can be equipped with an electronic flow control.
