About the 50 Series The newest model of the legendary Binary Stream Gas Analyser from AGC Instruments is used to measure N2, H2, He, CO2, Ar or other gases in Binary gas mixtures or pure gases. We monitor impurities in a major gas based on the difference of thermal conductivities. Using hotwire or thermistor elements, this analyser with its robust platform, achieves high accuracy and sensitivity with a response time of <30 seconds (T90). To interface with the analyser is via the new 5.7" QVGA LCD Touch Screen display, where all statuses, alarm conditions, diagnostics and direct reading of results are available with ease. Using high quality flow detection devices with alarms, the gas flows are measured & displayed to the LCD display ensuring accuracy and stability to allow great confidence in all results. The 50 Series model contains a temperature regulated TCD which allows continuous monitoring of the gas stream. Through the use of solenoid valves, drift has been eliminated as a constant reference to Zero gas is utilised for greater accuracy. Using temperature control of the measuring sensor, excellent temperature stability is guaranteed with <1% drift over a 24 hour period. Principle of Operation The Detector consists of an electrically heated hotwire (or thermistor) element in a temperature regulated metal housing. The detection principle is based on any change in the thermal conductivity of the gas flowing through the detector will change the rate of heat loss from the element to the metal housing. The signal resulting from the temperature change is proportional to the change in sample gas conductivity.
