1. Signal output: RS-485 bus, modbus/rtu protocol, easy to connect to PLC, DCS, industrial control
computer, general controller, paperless recording instrument or touch screen and other third-party equipment.
computer, general controller, paperless recording instrument or touch screen and other third-party equipment.
2.For the patented ammonium ion electrode, the internal reference solution exudes from the microporous salt bridge very slowly under the pressure of
at least 100KPA (1bar). Such a reference system is very stable, and the electrode life is longer than that of ordinary industrial electrodes.
