IOT-485-pH Digital pH Sensor | Calibration Guide

Accurate pH measurement is essential for water treatment, chemical processing, and industrial process control. In this video, we show the calibration procedure for the IOT-485-pH digital pH sensor.

The IOT-485-pH is a digital pH sensor with RS485 communication, designed for continuous online monitoring and IoT integration. It supports temperature compensation and menu-driven calibration for fast on-site maintenance. The calibration process includes preparation, sensor connection check, entering calibration mode, zero calibration with pH 7.00 standard solution, slope calibration with pH 4.00 or pH 10.00 standard solution, calibration verification, and returning to online measurement.

After calibration, the sensor provides stable pH readings and digital output for integration with PLC, DCS, SCADA, or IoT platforms. Typical applications include wastewater treatment, drinking water, surface water, industrial process water, aquaculture, and smart water monitoring systems.

More calibration videos and operation guides are available on our channel. This video is intended for water quality, maintenance, and process engineering teams.

BD100 4-20mA pH/ORP Module + PH5806 High-Temperature pH Sensor | Calibration Guide
---> Mob/WA:86-15000087545

Regular calibration is essential for accurate pH and ORP measurement in high-temperature industrial processes. In this video, we show the calibration procedure for the BD100 4-20mA pH/ORP module paired with the PH5806 high-temperature pH sensor.

The BD100 is a compact 4-20mA pH/ORP transmitter module designed for panel or online integration. The PH5806 high-temperature pH sensor is suitable for continuous measurement in elevated-temperature process water. Together they provide reliable pH/ORP readings and a standard 4-20mA signal for PLC, DCS, or display instruments.

The calibration steps include preparation, sensor connection check, entering calibration mode, temperature compensation setup, zero calibration with pH 7.00 standard solution, slope calibration with pH 4.00 or pH 10.00 standard solution, ORP calibration when applicable, saving the calibration data, verification, and returning to online measurement. Ensure the sensor is cooled to a safe temperature before handling if required by your process.
