The TS-270 professional online residual chlorine electrode employs three electrodes (working, reference, and counter) and constant voltage technology to get very precise readings of the residual chlorine, chlorine dioxide, and ozone in water. By maintaining the electrode surface potential steady, it may preferentially find target chemicals.
A gel reference electrode and high-purity platinum ring working electrode are included. The corrosion-resistant, structurally solid glass shell is ideal for drinking, circulation, pool, and other clean media. The water, chemical, food, swimming pool, and other sectors use it to check disinfection.

Core Highlights
- Monitoring chlorine dioxide, ozone, and residual chlorine without replacing electrodes is accurate and cost-effective.
- The constant pressure method is very suitable for precise monitoring of drinking water due to its linear signal, excellent zero stability, and ≤ 1% inaccuracy.
- The electrode blocks suspended particles in the water, and the carefully protected controller prevents electromagnetic interference, making it very suitable for long-term tracking of clean water quality.
- Very flexible: can be used with most compatible instruments, can be installed in flow and water tanks, and can adapt to different needs.
Measuring principle
Constant voltage electrode:The TS-270 residual chlorine electrode is a constant voltage sensor composed of two platinum electrodes and a reference electrode
A micro battery measurement system. Maintain a stable potential at the electrode measurement end during measurement, and measure different potentials
Under this potential, different and linearly good current intensities are generated.
Featured Applications
- The municipal water supply industry‘s “Sanitary Standards for Drinking Water” demand residual chlorine monitoring of water plant and secondary effluent for disinfection safety.
- Industrial circulating water system: chlorine dioxide cooling water disinfection monitoring to minimize microbiological growth and equipment damage, optimum disinfectant dosage.
- An overlimit alarm controller and real-time residual chlorine monitoring ensure pool/hot spring water hygiene and user satisfaction.
- Pure water preparation: residual chlorine/ozone monitoring before reverse osmosis membrane to prevent oxidant damage and equipment life.

Electrode diagram illustration

- After opening the packaging, check for mechanical damage to the electrode cap and electrode body;
- Select the corresponding electrode sleeve or cable head for installation according to different electrodes;
- The connection between the electrode wire and the electrode is not waterproof, please make sure to do a good job of waterproofing.
Wire stripping instructions

Attention
- Flow installation: The constant voltage residual chlorine electrode must be used in conjunction with a flow channel to maintain stable flow rate, and the flow rate should be controlled at around 30-60L/H.
Daily maintenance and precautions
Maintenance points
- When installing, choose matching protective sleeves or cable connectors to ensure that the threaded interface is tightly sealed and avoid water leakage.
- The connection between the electrode wire and the electrode is not waterproof, and waterproof treatment should be done to avoid moisture affecting signal transmission.
- When stripping the wire, it is necessary to peel off the metal mesh layer, thoroughly remove the conductive black skin on the outer layer of the transparent central axis, and there should be no additional contacts in the middle.
- Avoid electrode contact with sharp objects to prevent membrane damage; The installation location should be away from strong magnetic fields and mixers to ensure stable measurement.
- Before the first use, it is necessary to connect polarization with the host and complete zero and slope calibration according to the host calibration process to improve measurement accuracy.
Safety precautions
- Every three to six months, wash the surface with clean water to get rid of anything stuck on it. This keeps the membrane’s water moving.
- Clean, seal, and store the electrode somewhere dry if you’re not going to use it for a while. The barrier won’t break down because of this.
- It is important to check the cable link and make any changes that are needed to make sure the signal gets through if the test data changes.
- Heavy acid or alkaline liquids can damage electrodes over time, so don’t leave them in them for too long.
