Industrial online PH meter
Suitable for water quality monitoring in chemical, oil refining, metallurgy, pharmaceutical, power station and environmental protection fields.
1. Chinese interface, easy to operate, the screen has a backlight function, easy to read;
2. It can measure the pH value/ORP value and temperature of the water sample, and the pH/ORP needs to switch display;
3. Support automatic temperature compensation;
4. Automatically identify three standard solutions of pH4.00, pH 6.86 and pH 9.18, supporting one-point calibration and two-point calibration;
5. Support automatic upper and lower limit alarm function and power failure protection function;
6. With (4 ~ 20) mA DC isolation signal output, the output upper limit and output lower limit can be arbitrarily set;
7. IP65 protection rating.
8. PHG-21C, the instrument built-in measuring board, can be directly connected to the electrode, used in the distribution flow cell. Suitable for applications where the measuring point and instrument distance are close. Can be equipped with transmitter: PHGF-46.
9. PHG-21D, the instrument does not have a front measuring board and must be used with a transmitter equipped with a front measuring board. Suitable for applications where the measuring point and the instrument are far away. Can be equipped with transmitter: PHGF-27B, PHGF-28B, PHGF-43.
