Features

✅ High‑Pressure & Deep‑Submerge Capacity IP68 protection rating; withstand 6 bar pipeline pressure for pipe mounting, submersible up to 50 m water depth. Dual‑installation mode: thread pipe installation / submerged bracket mounting, with 3/4"NPT & 1/2"NPT thread interface.

✅ Digital RS‑485 Modbus RTU Output Standard Modbus RTU (0x03 /0x06 /0x10), default 9600‑N‑8‑1; address 1‑255, support broadcast command. Power supply DC 5‑30 VDC, low power consumption, easy connection with PLC, HMI, data logger and IoT system. Remote configure & calibrate over RS485 bus.

✅ High‑Precision Measurement

PH2170: 0‑14pH range, accuracy ±0.02pH, resolution 0.01pH

ORP2170: ±1000 mV range, accuracy ±0.2 mV, resolution 0.1 mV Built‑in temperature sensor for automatic temperature compensation. Multi‑points pH calibration (up to 3‑point), single‑point ORP calibration, support NIST / USA standard buffer solution.

✅ Flexible Customizable Sensing System Optional sensing glass bulb (spherical / flat), junction choices: single ceramic, double ceramic, PTFE sleeve, ring‑PTFE junction for river, aquaculture, seawater, low‑conductivity water, strong acid‑alkali conditions.

✅ Refillable Electrolyte & Replaceable Electrode Tip Independent electrolyte refill port; inject refill solution on‑site without disassemble whole sensor. Glass electrode head can be replaced by special tool, no need to change the digital main body, lower total ownership cost.

✅ Robust Mechanical Construction Housing: PP+PC+PBT engineering plastic; TPU 4‑wire integrated cable OD5.5 mm. Clear wrench position for installation to avoid seal damage and water ingress. Spare accessories available: Y‑shape tee, protective cap, replaceable electrode, reference electrolyte liquid 30 ml etc.

✅ Maintenance & Warranty Terms pH electrode head: 6‑month warranty; ORP electrode head:12‑month warranty; digital circuit board:12‑month warranty. Recommended cleaning cycle:4‑8 weeks; calibration cycle:1‑3 months according to media conditions.
