SH-pH200 pH digital sensor
Overview
The SH-pH-200 pH digital sensor uses the glass electrode method, a corrosion-resistant housing, a built-in NTC temperature sensor and a compensation algorithm. The sensor has an RS485 interface and standard Modbus protocol.
Product features
- Industrial-grade composite pH electrode for harsh operating environments
- NTC temperature compensation, accuracy up to ±0.1°C
- Internal storage of calibration data
- Corrosion-resistant housing, waterproof grade IP68 for long-term underwater work
- RS485 communication interface, standard Modbus protocol for easy integration.
