Renke RS485 Multi Parameter Temperature pH Ec TDS Water Quality Sensor for Water Treatment

Replaces five separate instruments with a single integrated unit, reducing installation space, wiring complexity, and sensor coordination overhead in water quality monitoring systems.

K=1 covers 1 to 2000 uS/cm for purified and freshwater applications, while K=10 extends to 20000 uS/cm for industrial wastewater, brackish water, and high-dissolved-solids environments.

Covers strongly acidic to strongly alkaline water across industrial wastewater, agriculture, and aquaculture applications with fine-resolution output for precise process control decisions.

Supports both automatic real-time temperature compensation and manual mode with user-defined reference temperature, allowing flexibility between monitoring and lab measurement scenarios.

User-configurable EC temperature coefficient accommodates different water types where standard 0.02 per degree C compensation may not apply, improving conductivity accuracy in applications.

Full IP68 waterproofing and 0.6MPa pressure tolerance enable long-term deployment in rivers, aquaculture tanks, and industrial basins without housing degradation or seal failure over time.

Each unit is strictly calibrated at the factory, eliminating the need for on-site calibration equipment immediately after delivery, enabling fast commissioning in field monitoring systems.

Under normal conditions, recalibration is recommended only every 3 months, with frequency adjusted based on actual contamination levels, reducing maintenance frequency in stable water environments.

Maximum 0.4W consumption across a wide 7 to 30VDC input range supports solar or battery-powered remote deployment in agricultural irrigation, fish ponds, and off-grid water monitoring stations.

Standard 5m cable can be extended to any required length at time of order, enabling flexible routing from submerged probe to surface-mounted data loggers without on-site cable splicing.
