-5°C to 50°C (Instrument and sample gas)
3.5 – 29 PSI (0.25 Bar - 2 Bar)
Ambient (for pump equipped systems)
90-260 VAC, 40VA
General Purpose
USB 1.0 / 2.0 and RS485
Refer to the drawing B900 176 at the rear of the manual Appendix 1.
Two with volt free c/o contacts fully
configurable over the complete oxygen range,
one fault alarm.
Contact rating 5A @ 250VAC/30VDC
Software configurable over the entire oxygen range for either :
Current: 4-20mA isolated
Current 0-20mA isolated
Thermal Mass Flow sensor
Allows connection to a cylinder of gas with a certified level of oxygen.
Analyzer will correct to recorded level at programmed intervals.
Improves the response time of the analyzer due to sample transport lag by
adding a fast side stream.
Allows the instrument to be used in situations where there is no pressure to
the sample gas.
Allows the instrument to be used in situations where the sample gas will
react with either brass or copper fittings and pipes. Note: stainless steel
flowmeter and regulator will also be required.
