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 interference. It features an advanced pH probe with a pressurized reference system ($\ge\text{100 kPa}$). This system ensures a slow, continuous electrolyte seepage for over 20 months. This stabilized system effectively doubles the electrode’s operational lifespan compared to conventional alternatives.

The system transmits data via RS-485 (Modbus/RTU protocol) for universal compatibility with PLCs, DCS, and touch-screen controllers. The mechanical design includes a 3/4 NPT pipe thread. This facilitates simple and secure mounting in submersible applications, tanks, or pressurized pipelines.
