Signal output: RS-485 (Modbus/RTU protocol).
Convenient connection to third-party devices such as PLCs, DCS, industrial control computers, general-purpose controllers, paperless recording instruments or touch screens.
Dual high-impedance differential amplifier with strong anti-interference and fast response.
The patented pH probe, the internal reference solution oozes extremely slowly from the microporous salt bridge at a pressure of at least 100 kpa (1 Bar), and its forward bleed continues for more than 20 months. Such a reference system is very stable and the electrode life is extended by a factor of two compared to conventional industrial electrodes.
Easy to install: 3/4 NPT pipe thread for easy submersible installation or installation in pipes and tanks.
IP68 protection grade.
