Carbon dioxide can generally be produced by high-temperature calcined limestone or the reaction of limestone with dilute hydrochloric acid. Mainly used for refrigerating perishable food (solid), refrigerant (liquid), manufacturing carbonized soft drink (gaseous state) and solvent for homogeneous reaction (supercritical state), etc. Regarding its toxicity, research shows. Low-concentration carbon dioxide is non-toxic, while high-concentration carbon dioxide can poison animals. Carbon dioxide, a carbon-oxygen compound, has a chemical formula of CO2 and a weight of 44.0095. It is a colorless, odorless or colorless and odorless gas under normal temperature and pressure. And its aqueous solution is slightly acidic gas. It is also a common greenhouse gas. One of the components of air (0.03%-0.04% of the total volume of the atmosphere). The following introduces the function of the Jingxun Changtong fixed carbon dioxide sensor and the function of the fixed carbon dioxide sensor.
Description of fixed carbon dioxide sensor
The fixed carbon dioxide sensor is a gas sensor specially developed to detect the concentration of carbon dioxide in certain harsh environments. The CO2 sensor adopts a cast aluminum explosion-proof housing, the probe is placed in a special metal probe compartment. And the electrical part is isolated from the probe. The carbon dioxide sensor can collect changes in the concentration of carbon dioxide in the environment in real time online 24 hours a day. The change is converted into an electrical signal and transmitted to the supporting controller. The explosion-proof carbon dioxide sensor is specially developed for some harsh environments. Cast aluminum type explosion-proof housing, the probe is placed in a special metal probe compartment. And the electrical part is isolated from the probe.
Adopt professional test carbon dioxide concentration sensor probe as the core detection device. It has a wide measuring range, high precision, fast response and long life. Good linearity, good versatility, easy to use, easy to install, long transmission distance, moderate price and other characteristics. Note that the sensor is used for air detection, and the customer should test in the application environment to ensure that the sensor meets the requirements.
