Instrumentation used in the series of imports of electrochemical sensor can be measured, respectively, CO, H2, H2S, SO2, can be
Widely used in coal, petrochemical, metallurgy, electric power and environmental protection industries, the measurement object and
Measuring range is as follows:
H2 measurement object
Measuring range 0-1000ppm
Instrument characteristics
1. Import electrochemical sensor with stable performance, long life characteristics.
2. The use of large-screen dot-matrix liquid crystal display, Chinese man-machine dialogue menu, easy to operate.
3. Automatic equipment with historical data storage function, storing the user to set the cycle.
4. Oxygen alarm, the lower limit of the measured value can be set arbitrarily.
5. Instrument has a standard RS-232 I used for two-way communication with the computer.
