Hot Selling Ph Controller for Irrigation
Product Overview
1) Product overview
Product Features
- The Hot Selling pH Controller (model PHG-2081S) is a digital online pH/ORP/temperature meter designed for continuous monitoring and control in water systems.
Product Value
- It uses a digital pH/ORP sensor with RS485 Modbus communication and stores calibration data in the sensor for plug-and-play reinstallation.
Product Advantages
- Rugged IP65 ABS housing supports panel, wall or pipe mounting; compact size (144×144×104 mm) suits industrial and agricultural installations.
Application Scenarios
2) Product features
- Digital pH/ORP sensor with RS485 Modbus for long-distance, precise online measurement.
- Measurement ranges: pH -2.00 to 16.00 (±0.01 pH), ORP -2000 to +2000 mV (±1% FS), temperature -30.0 to 130.0 °C (±0.5 °C).
- Two isolated 4–20 mA outputs (for pH/ORP and temperature), RS485 Modbus RTU, data-logging and history curve display.
- Three relays (high/low alarms and automatic cleaning control), IP65 protection, and calibration saved on the sensor to reduce downtime.
3) Product value
- Enables accurate, continuous control of water chemistry to protect crops, equipment and processes.
- Reduces labor and maintenance costs through sensor-side calibration storage and predictive maintenance features.
- Provides remote monitoring and integration with automation systems via Modbus, supporting fast, data-driven decisions for irrigation dosing and water quality management.
4) Product advantages
- High precision and stability suitable for harsh field or industrial environments.
- Digital sensor architecture improves reliability and simplifies replacement—calibration remains with the sensor.
- Flexible outputs and alarm relays support direct control of dosing pumps, valves and cleaning cycles.
- Backed by BOQU’s R&D, after-sales service and experience, ensuring technical support and customized solutions.
5) Application scenarios
- Irrigation systems: fertigation control, nutrient solution monitoring in greenhouses and hydroponics, drip and sprinkler systems.
- Agricultural water management: reused/recycled irrigation water monitoring and automated dosing to prevent crop stress.
- Other uses: wastewater and drinking water monitoring, fermentation and food production process control, environmental monitoring and industrial water treatment.
