An ORP sensor known as GRT1110P is utilized for the purpose of determining the redox potential in wastewater that contains chromium and in the manufacturing of circuit boards. This is accomplished by utilizing a platinum indicator electrode and a silver chloride reference electrode, utilizing a standard PG13.5 thread, being simple to build, and being outfitted with a protective cover. Because it is built to function in difficult situations, you do not need to be concerned about the treatment of wastewater from industrial areas.

Platinum+silver chloride composite electrode, reference internal resistance ≤ 10K Ω, reading does not drift
Easy installation:
PG13.5 standard thread, directly compatible with pipes/sheaths, can replace old electrodes
Easy to maintain:
Oil stains and organic matter are easy to clean, and there is no need to frequently replenish electrolyte
Wide range:
-1999~1999mV, covering multiple types of redox conditions in wastewater treatment
Ideal Application Scenarios
Circuit board manufacturing: Continuously monitor the oxidation-reduction potential (ORP), maintain stable values, and reduce pollution during etching, cleaning, and wastewater treatment processes.
Chromium containing wastewater treatment: The key is to track the reduction process of hexavalent chromium (such as Cr ⁶⁺ converted to Cr ³ ⁺), confirm the effectiveness of the treatment, and ensure compliance with sewage discharge standards.
Factory wastewater treatment: A redox control process suitable for the chemical, electronic, and electroplating industries, which requires accurate ORP data to ensure that the treatment results meet the standards.
Usage and Maintenance Guide
- Before you take a measurement, make sure the reference joint and platinum sensing area are both fully underwater in the sample. Use a clean cloth to wipe the silver surface to get rid of any dirt that isn’t stuck.
- Cleaning Instructions:
- Gently wipe the silver piece with a cloth soaked in alcohol or acetone to get rid of oil stains.
- If you have biological materials that won’t dissolve, clean them with 30–50% hydrochloric acid and then rinse them with distilled water.
- Only use soft things! Platinum surfaces can be scratched very easily.
- Notes for Calibration:
- Use a newly made pH 4.00 quinhydrone-saturated buffer solution. It can only be used for two days.
- To keep things correct, you should calibrate them often (every 2 to 4 weeks for wastewater cases).
- Sensors should be washed with pure water and stored in a clean, dry place when not in use. Don’t soak it in pure water or other corrosive liquids for a long time.
- Water Protection: The part where the sensor wire connects to the body can’t get wet. Wrap it with waterproof tape or use a waterproof junction box to keep wetness out.
Sensor diagram illustration
- After opening the packaging, check whether there is mechanical damage to the sensitive bulb and sensor body of the electrode;
- Remove the sensor protective cover and check if there are any bubbles in the sensitive bulb of the sensor. If so, gently shake the sensor in a vertical plane to remove the bubbles;
- Select the corresponding sensor sleeve or cable head for installation according to different sensors;
- The connection between the sensor wire and the sensor is not waterproof, please make sure to do a good job of waterproofing.
Wire stripping instructions
Attention
- The outer layer of the transparent central axis is covered with a conductive rubber layer and a metal mesh layer. When stripping, first strip the metal mesh layer into the metal mesh as shown in the picture, and be sure to removal of conductive black skin on the transparent central axis;
- The cable extends to the host without any contact points except for a dedicated junction box.
