Water Quality Instruments and Sensors supplier in Saudi Arabia | DSTC water treatment and desalination

Water Quality Instruments and Sensors

أجهزة قياس جودة المياه والحساسات

Product Description

Stable water treatment depends on measuring pH, ORP, chlorine, conductivity and flow at the right time, and DSTC supplies the instruments and sensors needed to do that reliably. We support sensor selection, calibration solutions, spare probes, controller wiring, and automatic dosing control through 4-20 mA, pulse, or digital signals.

What to send for a quote

For quotation, send the measured parameter, pipe size, water type, temperature, pressure, required output signal, controller requirement, and installation location.

Overview

Instruments and sensors are the monitoring layer of a water treatment plant. They measure key operating values in real time, send signals to controllers or PLC panels, and allow the system to alarm, adjust dosing, and protect equipment. DSTC supplies instruments for pH, ORP, conductivity, TDS, chlorine, turbidity, dissolved oxygen, and pressure. These devices are commonly installed in RO systems, cooling towers, swimming pools, industrial process water lines, and wastewater treatment plants.

Applications

  • RO permeate quality monitoring by conductivity or TDS
  • Chlorination control using free chlorine or ORP measurement
  • Cooling tower bleed and chemical dosing by conductivity
  • Swimming pool pH and disinfection control
  • Wastewater pH, DO, turbidity, and pressure monitoring
  • Automatic dosing control through sensors, controllers, and PLC panels

Product Range & Specs

  • pH and ORP sensors with transmitters and controllers
  • Conductivity and TDS sensors for RO, cooling, and process water
  • Free chlorine, turbidity, dissolved oxygen, and pressure sensors
  • SEKO controllers for single-parameter and multi-parameter dosing control
  • 4-20 mA, pulse, relay, and digital outputs for pumps and PLC panels
  • Calibration solutions, spare probes, installation, and on-site calibration support
  • SEKO KemiDose controllers (pH, ORP, free chlorine) and SEKO K65 chlorination system

Product Summary

Water quality instruments and sensors monitor pH, ORP, conductivity, TDS, chlorine, flow and pressure so operators can control dosing, RO performance and process water quality. The correct setup depends on measurement point, signal output and calibration needs.

Frequently Asked Questions

Which sensors are required for an RO plant?+

Most RO plants use conductivity or TDS sensors for permeate quality, pressure instruments for operation monitoring, and pH or ORP sensors when chemical dosing or membrane protection requires it.

Can sensors control dosing pumps automatically?+

Yes. A controller can read the sensor value and adjust a dosing pump through 4-20 mA, pulse, relay, or digital signal to keep pH, chlorine, ORP, or conductivity within target range.

Do water quality sensors need calibration?+

Yes. pH, ORP, chlorine, and some conductivity sensors require periodic calibration. Accurate calibration is important because dosing decisions depend on sensor readings.

How long do pH and ORP probes last?+

Probe life depends on water quality, temperature, chemical exposure, and maintenance. pH and ORP probes are consumables and often require replacement faster than pressure or conductivity sensors.

Does DSTC provide sensor installation and wiring?+

Yes. DSTC can support sensor selection, installation, controller wiring, calibration, and integration with dosing pumps or PLC panels.
