Flow Alarm:
Thermal Mass Flow sensor
Auto Calibration
(option):
Allows connection to a cylinder of gas with a certified level of oxygen.
Analyzer will correct to recorded level at programmed intervals.
Bypass Flowmeter:
Improves the response time of the analyzer due to sample transport lag by
adding a fast side stream.
Sample Pump
Allows the instrument to be used in situations where there is no pressure to
the sample gas.
Stainless Steel
Fittings
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
