Product DescriptionPH Sensor1. Product Introductions The PH Sensor is a digital sensor featuring an easy-to-integrate RS485 communication interface and standard Modbus protocol, It is equipped with a corrosion-resistant housing,IP68 protection rating, suitable for operation in various harsh working environments;Select an industrial-grade combination electrode with a double-junction reference electrode design for prolonged service life;Equipped with a built-in PT1000 temperature sensor and compensation algorithm, achieving an accuracy of ±0.1℃;2. Operation PrincipleThe glass electrode method for measuring the pH of water samples uses a saturated calomel electrode (SCE) as the reference electrode and a glass electrode as the indicator electrode.These electrodes form an electrochemical cell with the water sample, and the electromotive force (EMF) of the cell is measured by a pH meter, which directly displays the pH value.This method is accurate, rapid, and minimally affected by interference from factors such as water color, turbidity, colloidal substances, oxidants, reductants, and salinity.Features1. Signal Output: RS-485 (Modbus/RTU protocol). Facilitates seamless integration with third-party devices such as PLC, DCS, industrial PC, universal controllers, paperless recorders, or touchscreen;2. Dual high-impedance differential amplifier, offering strong anti-interference capability and high-speed response;3. The company holds a patented pH electrode technology, where the internal reference solution permeates extremely slowly through the microporous salt bridge under a pressure of at least 100 kPa (1 bar), with continuous efflux sustained for over 20 months.4. Easy Installation: 3/4 NPT (National Pipe Thread) pipe threads enable submersible mounting or integration into pipelines and tanks;5. IP68 protection class;Installation The sensor can't installed upside down or horizontally; it should be mounted at an angle of at least 15 degreesTechnical Specification(Custom configurations available upon request.)Measurement parameterpHTemperature resolution0.1 ℃Measurement principleGlass Electrode MethodTemperature precision0.5 ℃Measurement range0~14PHVoltageDC12V~DC24VMeasurement precision±0.1PHCommunication methodRS485 ( Modbus RTU )Resolution0.01 PHProtection classIP68Company ProfileWho we areShenZhen StarWSN is a professional liquid level and water quality monitoring device company which established in 2016.
