Waghmart pH & DO Sensor Set for STP-01

36000 Rs.  32400 Rs

The Waghmart Sensor Range is designed to monitor and control critical parameters in Sewage Treatment Plants (STPs) and Effluent Treatment Plants (ETPs). These sensors ensure consistent water quality, optimize process efficiency, and help operators meet CPCB discharge norms.

Waghmart STP sensors include pH, DO (Dissolved Oxygen), ORP (Oxidation Reduction Potential), TSS (Total Suspended Solids), Flow, and Level Sensors. Built with industrial-grade housings, these sensors withstand harsh environments while delivering high-accuracy data. When integrated with SCADA or PLC systems, they enable automated plant control and remote monitoring.


  • High Accuracy & Stability – ±0.1% error margin with quick response time

  • Wide Range of Measurements – pH, DO, ORP, TSS, turbidity, flow & level

  • Rugged Construction – IP68-rated waterproof sensors for continuous immersion

  • Easy Integration – Modbus / 4-20mA / RS485 outputs for PLC & SCADA

  • Real-Time Data – Enables quick decision-making and compliance reporting

  • Low Maintenance – Self-cleaning probes with minimal calibration needed

  • Digital Display Option – Handheld or panel-mounted display available


  1. Identify Parameters to Monitor – Select required sensors (pH, DO, TSS, etc.) based on process needs.

  2. Install at Critical Points – Place sensors in equalization tanks, aeration tanks, clarifiers, or treated water outlets.

  3. Connect to Control System – Wire sensors to PLC/SCADA or standalone display units.

  4. Calibrate Before Use – Follow standard calibration using buffer solutions or calibration kits.

  5. Monitor & Maintain – Regularly check readings, clean probes, and recalibrate as per recommended schedule.
