Industrial Grade pH Sensor KE- pHS 1003

The industrial standard KE- pHS 1003 sensor is a high temperature pH electrode used for continuous monitoring of surface water, ground water and industrial effluent water. This specific pH probe can withstand high temperature and quick media changes of cleaning processes and still perform accurately without maintenance intervention. It also helps meet regulatory audit requirements for accuracy and productivity in biotech, pharmaceutical and food/beverage industries.

Sensor Features
1. Gel and solid polymer electrolyte extend electrode life even in harsh environments.
2. High accuracy with fast response and good repeatability.
3. PT1000, the temperature element used in the KE- pHS 1003 sensor is highly accurate
and linear throughout the range.
4. High pressure design is good for installation in tanks and reactors

Sensor Installation

1- Do not put Sensor directly into water, the sensor should be installed with Female Thread Socket for Inline Flow through Measurement and Threaded Sensor Housing for Offline Measurement.

2- Before installation, use Teflon Tape (at 1/2" Thread) to ensure no leakage occurs.

3- Connect the Sensor to Controller, let it stable for 3 minutes, then start calibration work.

4- Connect / Insert the Sensor vertically upright in the Solution whenever doing calibration.

5- Sensor to be installed Inline to piping where the pipe line doesn’t get dry whenever process is not operational.


Sensor Maintenance

1- Throw off air bubbles that are noticed on the glass bulb, otherwise it will cause measurement errors.

2- Check if the tinned wires are dry and clean, otherwise use ethanol to clean and blow some air to wipe out dust particles.

3- Stir the test solution with sensor to accelerate sensor response when calibrating than place the sensor in calibration solution.

4- Use 2 Points or 3 points calibrations with any NIST standard and TCT standard buffers for use with RCB pH controller KE-pH 1000.

5- The sensor should be cleaned and calibrated periodically.


Sensor Wiring and Connections

2. KE-pH 1000 Controller Connections Layout

Image above shows the wiring connection names for RCB pH Sensor KE-pHS 1003 and RCB pH Controller KE-pH 1000. Each Sensor wire connection detail is given below:

1- For 2 wire temperature sensor, short T/P4 and T/P3. Connect TEMP Wire 1 (Pink) with T/P 1 and TEMP Wire 2 (Black) with T/P 2.

2- Connect INPUT Wire 3 (Copper) with GLASS connection of Controller.

3- GND Wire 4 (Green) can be used if required.

4- Connect REF Wire 5 (Yellow) with REF connection of Controller.


1- In case of any issue other than mentioned above, immediately inform RCB representative about the issue which will be resolved at the earliest.

2- Special fittings Inline or Offline for pH Sensor KE-pHS 1003 can be ordered to RCB separately

3- Buffer Solutions (4.00, 7.00, and 10.01) for Calibration of pH Sensor KE-pHS 1003 can be ordered to RCB separately.
