FAQs - Chlorine Gas Sensors
What is chlorine gas?
Chlorine gas is a simple substance formed from the element chlorine, and its chemical formula is CL2. It is a yellow-green toxic gas with a strong pungent odor.
Why is measuring chlorine gas important?
Chlorine is a toxic gas, excessive inhalation can lead to poisoning and death. Therefore, chlorine gas detectors should be installed in chlorine production, storage and use places for real-time monitoring. Once chlorine leakage is detected, timely measures will be taken. You can choose the right CL2 gas sensor according to your environment.
How do chlorine gas sensors work?
Most chlorine gas sensors measure the concentration of chlorine in the environment via electrochemical principles.
What are the types of chlorine gas sensors?
Depending on the use environment, chlorine gas sensor can be categorized into wall-mounted, duct type, portable and explosion-proof.
How accurate are Renke chlorine sensors?
Our chlorine gas sensor has a high measurement accuracy within ±10% and repeatability within 3%.
Where should a chlorine gas transmitter be installed?
The chlorine gas transmitter should be installed in a location free from impact, vibration, and strong electromagnetic interference, and easily accessible for maintenance. The clearance between the installation site and surrounding process piping or other equipment should not be less than 0.5m. It is recommended to install the device 0.3m to 0.6m from the bottom of the measuring space.
What industries use chlorine gas sensors?
Laboratory
Chlorine gas is one of the commonly used reagents in laboratories, and a leak could pose a serious threat to laboratory personnel and equipment. Therefore, the use of chlorine gas sensor in chemical laboratories can monitor the concentration of chlorine gas in time to prevent accidents.
Chemical Plant
Chlorine gas is widely used in chemical production, such as the production of plastics, dyes, disinfectants and so on. To prevent chlorine leakage, chlorine gas sensor needs to be installed for real-time monitoring.

The use of chlorine gas sensor can help wastewater treatment plants monitor chlorine concentrations to ensure safety during the disinfection process, while also protecting the health of staff.
Agriculture
Chlorine gas can be used in agriculture for disinfection and pest control, but too much chlorine can also damage crops and pollute the environment. The use of chlorine gas sensor can help agriculturalists monitor chlorine concentrations and minimize the impact on crops and the environment.
How do you calibrate chlorine gas sensors?
Our chlorine sensors are factory calibrated and ready for use. After long-term use, please contact technicians for calibration.
Where should a chlorine transmitter not be installed?
To ensure proper use of this equipment and prevent malfunctions, please do not install it in the following locations:
1. Locations directly affected by steam or fumes.
2. Locations with high airflow, such as near air inlets, exhaust fans, or doors.
3. Locations with high moisture content or water droplets (relative humidity ≥95%RH or locations where condensation may occur).
4. Locations exceeding the equipment’s operating temperature range.
5. Locations with strong electromagnetic fields.
How to wire this chlorine gas sensor?
