Product Overview

The RS485 & 4-20mA Current pH Sensor (S-pH-01A) offers high accuracy, fast response, and good repeatability for pH measurement. It features a wide range power supply and is suitable for long-term immersion in soil or water due to its advanced, clog-resistant junction design and excellent anti-corrosion performance. The sensor provides automatic temperature compensation for accurate readings and offers flexible output options via MODBUS RS-485 or 4~20mA current. Its IP65 rating ensures waterproof capabilities for professional applications. This cost-effective, low-power, and compact sensor is easily integrated into various systems for both indoor and outdoor use.
