Residual Chlorine Detector- Water Quality Chlorine Sensor

About - Residual Chlorine Detector

Chlorine detector is a kind of industrial water quality sensor. The chlorine electrode is made of high-purity platinum with high protection level and can work normally even in harsh environments. This residual chlorine sensor has two signal outputs, RS485 and analog. Widely use measuring chlorine levels in natural water, surface water, groundwater and aquaculture applications

Chlorine Sensor

This chlorine sensor is a sensor independently developed by us to measure the chloride ion content in water. The chlorine electrode adopts the advanced non-membrane constant voltage measurement principle, does not need to replace the diaphragm frequently, does not consume reagents, and has stable working performance

FAQs

Why measure chloride ions in water?

Because tap water is often sterilized with CL2, there will be a lot of CL- in the water, and it is harmful to the human body, and CL2 is a toxic substance, so the water we usually drink needs to be stored for a period of time, so that the CL- in the water is released to the In the air, this is good for the human body.

How to maintain the residual chlorine electrode?

The chlorine sensor generally does not need routine maintenance. When there is an obvious failure, please do not open it to repair it yourself, and contact us as soon as possible!

After using the chlorine electrode, please clean the electrode head with clean water and cover the protective cover.

If dirt and mineral components adhere to the electrode diaphragm, the sensitivity will decrease, and sufficient measurement may not be performed. Please ensure that the platinum ring is clean.

The platinum induction ring of a good residual chlorine electrode should always be kept clean and bright. If the platinum ring of the electrode becomes rough or covered with contaminants after measurement, please clean it as follows: (for reference).

1. Inorganic pollution: Immerse the electrode in 0.1mol/L dilute hydrochloric acid for 15 minutes, gently wipe the platinum ring of the residual chlorine electrode with a cotton swab, and then clean it with tap water.

2. Organic or oil pollution: Immerse the electrode in tap water with a small amount of detergent, such as dishwashing liquid, and thoroughly clean the sensing surface of the electrode sensor. Gently wipe the platinum ring of the electrode with a cotton swab, and then rinse with tap water to complete the cleaning. If the platinum ring of the electrode has formed an oxide film, please use toothpaste or 1000-grit fine sandpaper to moderately polish the sensing surface, and then clean it with tap water.

How to calibrate residual chlorine meter?

1. Zero calibration:
Place the chlorine probe in the air and perform zero point after the value is stable.
2. Slope calibration:
Place the chlorine probe in the flow cell flowing with the residual chlorine standard solution, and perform slope calibration after the value is stable. It is recommended to use 1-2 mg/L HClO standard solution. Regarding the preparation and determination of standard solutions, please refer to the determination of residual chlorine in the national standard.
Note: The chlorine meter has been calibrated before leaving the factory. Because the preparation of the standard solution requires a lot of personnel, non-professionals may not be able to do this work. Only when the value is determined to be inaccurate, it is recommended that the user calibrates by himself.
