RS-485 pH Probe AT-SB-PROBE-pH-P

The sensor employs a double high-impedance differential amplifier to provide high-speed response and superior resistance to industrial interference. It features an advanced pH probe with a pressurized reference system ( ≥ 100 kPa) that ensures a slow, continuous electrolyte seepage for over 20 months. This stabilized reference system effectively doubles the electrode’s operational lifespan compared to conventional industrial alternatives.

Data is transmitted via RS-485 (Modbus/RTU protocol), ensuring universal compatibility with PLCs, DCS, and touch-screen controllers. The mechanical design includes a 3/4 NPT pipe thread, facilitating simple and secure mounting in submersible applications, tanks, or pressurized pipelines.
