The acid-base concentration meter is a water quality online monitor with a microprocessor
The acid-base concentration meter is a water quality online monitor with a microprocessor. The instrument is widely used in thermal power, chemical industry, steel pickling and other industries, such as the regeneration of ion exchange resin in power plants, chemical industry process, etc., to continuously detect and control the concentration of chemical acid or alkali in aqueous solution.
Features of acid-base concentration meter:
1. The transmitter cavity of the acid-base concentration meter is an integrated structure of plexiglass, with consistent process parameters, corrosion resistance, pressure resistance, and no leakage.
2. With automatic temperature compensation function, the single-chip microcomputer memory has temperature characteristic tables of five standard water samples of 0.8%, 2%, 4%, 6%, and 8% at 5°C-45°C, and the measured concentration voltage and temperature voltage The value checking operation is carried out to further improve the measurement accuracy.
3. With automatic calibration function: the user can perform zero and full calibration at any time during use, and store the zero and full deviations in the memory, and correct the measurement results during measurement to ensure the accuracy of the measurement.
4. The acid-base concentration meter adopts embedded ARM technology, which has strong anti-interference ability, measurement stability and repeatability. The indicators are greatly improved.
5. The operation is guided by the Chinese menu, which is convenient to use and maintain.
6. Increase the self-test CHK key, press and hold this key to observe the concentration potential E value is greater than a fixed value of 1.50V, and perform self-test on the sensor part accordingly.
7. The acid-base concentration meter adopts scanning display mode, which saves power and greatly reduces the power consumption of the meter, so that the meter can work for a long time under sealed conditions.
8. With a variety of output functions: isolated 4-20mA output mode, accurate current output and no drift; RS485﹑CAN bus and other output modes.
9. The temperature sensor of the acid-base concentration meter is isolated and sealed at the water inlet of the transmitter to track temperature changes in time. The temperature compensation has high precision and corrosion resistance.
10. Non-contact sensor, no special maintenance for electrodes.
11. The whole machine has no maintenance, and it can be put into operation for a long time after one adjustment.
The acid-base concentration meter is an intelligent instrument widely used in electric power, petrochemical, metallurgy and other industries to measure the concentration of ion exchanger regeneration solution. Using screen display, Chinese menu, guided operation, graphic curve, data recording and other technical means, the acid-base concentration meter has stable performance, convenient operation and no maintenance.
