Ask for a sample or a small pilot. Availability, minimum quantity and sample charges depend on the selected model.
Price & delivery
Range, interface, accessories, quantity and destination affect the quote. Stock, lead time, freight, taxes and delivery terms need confirmation.
Warranty & support
Coverage, duration, exclusions and the fault-assessment process are confirmed for the quoted model before order.
Certificates & documents
Tell us the destination and required standard. We check the exact model, document revision and available evidence; a family listing is not certification.
Public documents describe this product family and selection options. Wiring, register maps and compliance documents must match the model and version selected for your order.

How the model is selected
The written quotation ties the site requirement to one reviewed hardware configuration.
Site requirement
Application, medium, mounting and environment
Hardware configuration
Signal, protocol, power and enclosure
Quote confirmation
Model, quantity, certificates and delivery
Remote integration context
Sensors, interfaces, enclosure, power and mounting are confirmed against the actual project before quotation.
Choose the output and mechanical configuration together
The reviewed documents cover several related configurations. The values below are selectable limits, not a claim that every probe combines every option.
The reviewed measurement range is pH 0–14 with 0.01 pH resolution and a datasheet-listed accuracy of 0.01 pH.
Response is listed as 8 or 10 seconds to 98% in flowing liquid, depending on the selected configuration.
Select RS485 Modbus RTU or 4-20 mA together with the compatible receiving input. The reviewed supply is 7–30 VDC with consumption below 0.15 W.

Direct-cable, PG13.5/M8 and NPT3/4 threaded bodies with direct cable or an M16 waterproof connector are configuration choices, not universal features.
Temperature limits of 0–60, 0–80 or 0–100 °C and pressure limits of 0.6, 0.8 or 1 MPa depend on the selected mechanical variant.
Install the electrode vertically or at an angle with the sensing end down, away from trapped air and sediment. Keep the glass electrode wet in storage solution and plan periodic cleaning and calibration.

Applications
Instruments, enclosure, power and mounting are selected for the actual tank, well, reservoir or pump station.
Use this probe for continuous pH monitoring in water tanks, treatment basins, wastewater processes and compatible process-water lines. The reviewed family covers pH 0–14 measurement with RS485 Modbus RTU or 4-20 mA output families. Mechanical body, connector, cable, temperature rating and pressure rating vary by configuration and must be selected together before quotation.
Water-treatment and wastewater pH monitoring with planned calibration and cleaning access
Tank, basin and process-water immersion points where the electrode can remain wet
Threaded pipeline or flow-cell installations using a compatible pressure-rated variant
PLC, SCADA and remote-telemetry projects using RS485 Modbus RTU or 4-20 mA by configuration
Choose the output from the available PLC, RTU or gateway input and the required cable run. The reviewed product family provides RS485 Modbus RTU or 4-20 mA by configuration; the quotation confirms one compatible probe, wiring and receiving-input path.
Which temperature and pressure rating applies?
The rating depends on the mechanical variant. Reviewed configurations list 0–60, 0–80 or 0–100 °C and 0.6, 0.8 or 1 MPa. Share the liquid temperature, normal pressure, credible peak pressure and mounting method so the correct body can be selected.
How is the pH probe calibrated?
The reviewed RS485 configuration supports pH 4, pH 7 and pH 10 buffer calibration using one-, two- or three-point procedures. The calibration method, buffer set and acceptance interval are confirmed for the project.
How should the probe be installed?
Install it vertically or at an angle with the sensing end down. Avoid trapped bubbles, direct sediment loading and inaccessible locations. Immersion, flow-cell and threaded installations need different mechanical configurations.
What routine care does the glass electrode need?
Keep the glass electrode wet in 3 M KCl or the specified storage solution when it is out of service. Plan cleaning and calibration access; the reviewed guidance uses three- or six-month cleaning intervals depending on site fouling.
What should I provide when requesting a quote for the Industrial Water Quality pH Sensor?
Water / wastewater type, expected pH range and fouling conditions; Liquid temperature, normal / peak pressure and immersion / flow-cell / threaded mounting; Required RS485 Modbus RTU or 4-20 mA output and receiving PLC / RTU / gateway input; Body, connector, cable length, bracket and maintenance access
Where can I compare available model options?
