CO & CO2 Meters

Triplett offers CO and CO2 meters that help people assure indoor air quality by measuring CO, CO2, humidity, temperature, and dew points. They are widely used in restaurants, schools, offices, exhibition malls, and many public places. All our CO detectors and CO2 meters feature status indicators that change to depict good, normal, and poor along with the change in CO2 concentration in the room. All our indoor air quality meters feature a sensor that incorporates NDIR (non-dispersive infrared) waveguide technology and has a built-in CO2 automatic baseline calibration for long-term drift compensation. These meters are equipped with audio-visual alarms that inform people about abnormal concentrations. Our CO & Co2 sensors are backed with 1 -year warranty.

Maintaining indoor air quality is important to ensure the safety of people. CO and CO2 are two common gases produced as a result of human activities and various processes. These gases can have a detrimental effect on human lives.

Know More About Triplett CO and CO2 Meter

What is a CO and CO2 Meter?

The CO2 meters are devices designed to detect the carbon dioxide concentration of the area. Similarly, carbon monoxide meters are devices used to measure the presence of carbon monoxide in the air. These meters help prevent carbon monoxide poisoning.   

How do a digital Carbon Monoxide and Carbon Dioxide detector work?

The carbon Monoxide meter has a silicon microchip that sends an electric charge to other parts of the meter. A CO meter is a detector that produces an alarming sound when it identifies the CO gas concentration in the atmosphere. It measures the carbon monoxide components in parts per million (ppm). Indoor CO2 meters are usually measured with non-dispersive infrared (NDIR) or electrochemical energy. At Triplett, we provide handheld CO and CO2 measuring devices that are equipped with non-dispersive infrared (NDIR) sensors. These sensors feature an infrared source, a bandpass filter, a detector, and a light tube. The target gas, CO or CO2, gets identified through the filter wavelength. For instance, the wavelength for CO2 gas is 4.26 µm, and for CO gas is approximately 4.61 µm. Both these wavelengths are not commonly absorbed by other gases found in the atmosphere or moisture. This helps minimize the chances of cross-sensitivity. 

When the meter is in operation, the sensor detects the gas and pumps it to the light tube, which absorbs a certain wavelength. This absorption is converted into the electrical output, which alarms the user of the increased or normal concentration. The output is usually measured in parts per million (ppm). 

What is the purpose of the CO2 and CO Meter?

Co and CO2 measurement devices are advanced sensors that help in identifying the air quality. When carbon dioxide in the air rises, the quantity of volatile organic compounds (VOCs), odors, and other micro-organisms in the air also rise. The purpose of these sensors is to detect the amount of carbon dioxide and other harmful and poisonous gases present in the air.

What are the benefits of NDIR CO Detectors and CO2 Meters?

The following are the benefits of using NDIR CO and CO2 monitor. 

  • The NDIR sensors consume less power for operation, which perfectly meets the increasing demand for low power devices. 
  • Our Industrial CO testers and CO2 meters have fast stabilizing times, which is the minimal time needed for the sensor to switch from cold and hot conditions to take the measurement. 
  • Our indoor air quality meters can respond to high CO2 concentrations ranging from 500 ppm to 100% volume. 
  • These meters are compact sized and easy to carry around the areas where the gas is to be measured. 
  • These portable air quality meters assure long term stability as well as accuracy. 

Why is Carbon dioxide and Carbon Monoxide Detection Important?

Carbon monoxide is a toxic gas because it is combustible. Carbon monoxide poisoning has been one of the key concerns among employers across the world. Many people have already lost their lives due to carbon monoxide poisoning. The gas is generally produced by equipment and tools that are burnt on fossil fuels. High carbon monoxide concentration may lead to dangerous consequences. To avoid this, the Occupational Safety and Health Administration (OSHA) recommends employers take all necessary measures to protect the workers from carbon dioxide poisoning. Auto shops, mining areas, and ice rinks are common places where high concentrations of carbon monoxide are generally found. 

Carbon dioxide is used as a refrigerant in many industries. The gas is also naturally produced in the atmosphere by plants and by human bodies during respiration. A high concentration of carbon dioxide in an area will lead to depletion of oxygen, which will make it difficult for humans to breathe in. 

Triplett provides some of the best indoor quality meters that help measure the concentration of carbon monoxide and carbon dioxide in the air. Contact us today to know more. Our experts can help you choose the best suitable product for your application.
