GE600 Mirror Dew Point Meter

GE600 mirror dew-point meter, developed on the basis of the principle of cold mirror, It’s especially made for measuring gas humidity . Under a constant pressure, the gas with a certain velocity through the closed sensor chamber, by detecting the change of the photoelectric signal, using high precision circuit and advanced algorithms to control the refrigerating unit, the control system will eventually made the mirror surface temperature automatically balance on the sample gas dew point temperature, Then gas dew point temperature can be measured, the detection process of gas humidity has completed.

It Can be widely used in electric power industry, measuring departments, large-scale iron and steel, coal, chemical industry and other fields, it is mainly used for SF6, CO2, N2 and H2 and O2 gas micro water content detection. The maximum permissible error can satisfy the requirements of first level measurement performance for?national metrological verification regulations JJG 499-2004 ?. With advantages for fast measurement speed, high accuracy, small volume, light weight and so on .

• Display function: TFT4.2 color LCD touch-screen, real-time display the current measurement of dew point temperature, the equilibrium process chart, flow, time and other information.
• Alarm function: alarm prompt for wrong operation, abnormal gas flow or mirror checked exception .
• Self-test function: after power on, dew-point meter can automatically detect the configuration information (include sensor information, mirror clean and so on ), fault diagnosis function.
• Historical memory function: built-in FLASH, can store 510 measurements, convenient historical view.
• Double temperature measurement: an independent measurement of environmental temperature and mirror surface temperature.
• PPM display function: transform the current measurement of dew point value to PPM value display under 20?.
• Against the supercooled water: can effectively eliminate the error caused by supercooled water phenomenon..
• Dry type pipeline design: dry design for piping .
• SF6 temperature supply function: converting the current PPM value to PPMS.
• Factory calibration functions: automatic temperature calibration and manual calibration mode.
• Automatic/manual stop the measurement model.
• Selection of many kinds of measuring gas.
• Intelligent power display.
