Optimized for domestic sewage, agricultural sewage, and industrial wastewater, this durable ABS-housed probe combines a low-impedance hemispherical glass membrane with a double salt bridge system to capture precision data across a full 0 to 14 pH scale under pressures up to 4Bar.

The analog combination pH sensor is equipped with low-impedance hemispherical glass membrane, high strength and anti-breakage. Double junction reference design with large-area annular porous PTFE diaphragm for fast ion exchange, quick response.
ABS encapsulated housing for reliable protection. 1" NPT thread on both ends for versatile installation (submersion, flow cell, in-line). Integrated cable with customizable length. Optional built-in temperature sensor: PT1000 or NTC10K for automatic temperature compensation.
Analog signal output, compatible with most industrial pH transmitters and controllers, easy commissioning for general water monitoring.
The combined analog pH sensor is suitable for surface water monitoring, general wastewater, aquaculture water quality control, irrigation water pH measurement and other conventional water quality online monitoring.
