Best CO2 Leak Detector

The CO2 Leak Detector is used to monitor CO2 leaks in systems, instruments, fermentation, R&D, and process control. The unit has a sensitive resolution of 1ppm and a high range of 5000 ppm. This CO2 Leak Detector is designed with a built-in pump, making it excellent for detecting CO2 very fast and hence excellent to detect CO2 leaks. It also features an extendable probe for checking leaks in hard-to-reach places. The analyzer is built with a dual-channel NDIR CO2 sensor and a 32-bit microprocessor, ensuring accurate readings and user calibration. Its color screen, large digits, and real-time graphing make it easy to use and interpret. For those needing to detect higher concentrations of CO2, our 0-100% Carbon Dioxide Gas Analyzer is the more appropriate option.

Is CO2 Dangerous?

Yes it is.

A CO2 leak can be dangerous, especially in indoor confined rooms and spaces. CO2 gas can accumulate and increase in concentration. When that happens, the CO2 gas can displace oxygen and lead to asphyxiation.

In low concentrations, carbon dioxide is generally not harmful to humans. However, in enclosed or poorly ventilated areas, such as in buildings or confined spaces, a CO2 leak can cause the concentration of the gas to rise to dangerous levels. Breathing in high levels of carbon dioxide can result in symptoms such as dizziness, shortness of breath, headache, confusion, rapid breathing, increased heart rate, and in extreme cases, loss of consciousness or death.

Who Uses a CO2 Leak Detector?

CO2 leak detectors are a niche tools, but are used by various industries that employ CO2 gas. Here are some examples:

Industrial and manufacturing facilities: CO2 leak detectors are often utilized in industrial settings where carbon dioxide is produced, stored, or used. These include power plants, breweries, beverage manufacturing facilities, chemical plants, and food processing plants.
Restaurants and bars: Many restaurants and bars use carbon dioxide for carbonation in beverages such as soda and beer. CO2 leak detectors are employed to monitor storage areas, keg rooms, or any other spaces where carbon dioxide cylinders or systems are installed to prevent leaks and ensure a safe working environment.
Laboratories: Laboratories that handle chemicals, conduct experiments, or have controlled environments may use CO2 leak detectors to monitor CO2 levels. This helps maintain appropriate conditions and prevent the buildup of carbon dioxide in enclosed spaces.
Agricultural and horticultural settings: In certain agricultural practices, such as greenhouse cultivation or indoor farming, carbon dioxide is often supplemented to enhance plant growth. CO2 leak detectors can be employed to monitor CO2 levels in these environments and prevent excessive concentrations that may be harmful to humans or plants.

How to Test for a CO2 Gas Leak?

To test for a CO2 (carbon dioxide) leak, you can follow these general steps:

Ensure Safety: Before conducting any tests, ensure that you are in a well-ventilated area or wear appropriate personal protective equipment (PPE) if necessary. If you suspect a significant CO2 leak or are experiencing symptoms of carbon dioxide poisoning, evacuate the area and seek fresh air immediately. Don't forget that CO2 is heavier than air, so if you are in a shaft or confined space, take extra precautions.
Use a CO2 Leak Detector: Acquire a CO2 leak detector and use it at suspected leakage locations to pinpoint the increase in CO2 concentration. Leaks usually occur at gas lines, CO2 cylinders, junctions, and connectors.
Monitor the CO2 ppm Readings: Allow the CO2 detector sufficient time to sample the air and provide accurate readings. We recommend moving 1 inch per 2 seconds. Monitor the detector's display or indicators for any changes in carbon dioxide levels. If the detector has an alarm function, ensure that it is activated and set to an appropriate threshold.
Leak fixing: If as leak has been found. Take note of its location and tag the location. Ensure the breathable air does not exceed 5000ppm (otherwise evacuate). Address the leakage with an appropriate engineer or technician.

What Does A CO2 Gas Leak Smell Like?

CO2 gas is a colorless, odorless gas, so it does not have a smell. This makes it difficult to detect a CO2 gas leak without the use of specialized equipment such as a CO2 leak detector.

How to Test for a CO2 Gas Leak?

If you suspect you have a CO2 gas leak, you should use a tool such as a CO2 Leak Detector.

Begin by turning on the CO2 Leak Detector and allowing it to start operating after the countdown.
Next, perform a quick bump test to ensure the analyzer is functional. You can do this by breathing at the input port. The point here is to confirm the CO2 Leak Detector is indeed operating.
Once you have completed the bump test, take the CO2 Leak Detector and scan the area of interest, moving about 2 seconds per inch. Be patient and thorough to ensure you capture any CO2 gas.
Typical areas of leakage occur around connections, valves, line bends, and junctions. Make sure to check these locations.
Observe the detector's response. The units have a digital readout in PPM so it is very sensitive.
If you have confirmed a CO2 gas leak, ensure you take appropriate action to maximize safety.

How Long Does the CO2 Sensor Last?

The lifespan of a CO2 (carbon dioxide) NDIR (Non-Dispersive Infrared) sensor last between 5 to 15 years. Generally, CO2 NDIR sensors are designed to have a long operational life with stable performance. The sensor's lifespan is influenced by factors such as operating temperature, humidity, exposure to contaminants, and the frequency of calibration and maintenance.

How often should I test or calibrate my CO2 leak detector?

You should bump test before using the CO2 leak detector. Calibration should be performed between 6 to 12 months. Calibration can be done by our lab or you can perform the calibration yourself with our video tutorials.

Will a CO2 Gas Leak set off Carbon Monoxide Detector?

No, a CO2 gas leak will not set off a carbon monoxide (CO) detector. Carbon monoxide detectors are specifically designed to detect and alert occupants to the presence of carbon monoxide gas. Carbon monoxide and carbon dioxide are two distinctly different gases. Don't get confused.

How Does a CO2 Leak Detector Work?

A CO2 leak detector typically uses a sensing technology called NDIR to detect the presence of carbon dioxide gas in the surrounding environment. Here's a basic overview of how a CO2 leak detector works:

Infrared Light Source: The detector contains an infrared light source that emits a specific wavelength of infrared light, typically in the range of 4.2 to 4.4 micrometers. This wavelength is selectively absorbed by carbon dioxide molecules.
Gas Sample Collection: The detector collects a sample of the surrounding air or gas mixture through an inlet or sampling port. For the CO2 Leak Detector, the unit has a pump that forces the air in the chamber for a faster leak detection response.
Infrared Sensor: The detector incorporates an infrared sensor that consists of a detector element, typically made of pyroelectric or thermopile material. The sensor is designed to detect the infrared light after it has interacted with the gas sample.
Absorption Measurement: When the infrared light passes through the gas sample, carbon dioxide molecules absorb some of the light at the specific wavelength emitted by the light source. The amount of light absorbed is directly proportional to the concentration of carbon dioxide present in the sample.
Signal Conversion: The infrared sensor measures the intensity of the light that has passed through the gas sample and converts it into an electrical signal. The magnitude of the electrical signal corresponds to the amount of absorbed light and, in turn, indicates the concentration of carbon dioxide in the environment.
Threshold and Alarm: The CO2 leak detector is typically programmed with a predetermined threshold or alarm level for carbon dioxide concentration. If the detected concentration exceeds this threshold, the detector triggers an audible and/or visual alarm to alert individuals of the potential CO2 leak.

How Should I Store my CO2 Leak Detector?

To ensure maximum sensor life and accurate measurements upon operation, it is recommended to store the Sewer Gas Detector in a moderate environment with a humidity level of 50%RH and a room temperature of approximately 70F. The unit should be kept in the hard waterproof case it was sold with for optimal storage conditions.

Difference Between a CO2 and CO Leak Detectors?

CO and CO2 are two different gases. Often these two gases are confused and mixed up between people and can be dangerous. CO2 is carbon dioxide and CO is carbon monoxide. Our carbon monoxide leak detector is also available.

Conclusion

A CO2 leak detector is a device designed to find CO2 gas leaks along various gas lines and connections.
They help identify and locate potential CO2 leaks before they become a health hazard as CO2 can accumulate and deplete the oxygen in an indoor space.
A CO2 leak detector should be used with an appropriate pinpoint probe, built-in pump (to increase detection speed), and display CO2 concentration in ppm.
Be patient and slow when using a CO2 gas leak detector. It can take some time.
