Installation instructions:

1. Please connect the electrode foot correctly, the wrong connection position will affect the normal work of the sensor; Sensors should avoid contact with organic solvents, paints, oils and high concentration gases; Do not use adhesive directly on or near the sensor to prevent breakage of the plastic casing.

2. Target gas is recommended for calibration. If cross-sensitive gas is used for calibration, the accuracy of calibration and measurement cannot be guaranteed.

3. Cross sensitivity can fluctuate by up to 30% and may vary with the production lot of the sensor and the life of the sensor.


What is hydrogen chloride gas?

Hydrogen chloride, chemical formula HCl, a hydrogen chloride molecule is composed of a chlorine atom and a hydrogen atom, is colorless and pungent odor of gas. Its aqueous solution commonly known as hydrochloric acid, scientific name hydrochloric acid. Hydrogen chloride is very soluble in water, at 0℃, 1 volume of water can dissolve about 500 volumes of hydrogen chloride. Hydrogen chloride is mainly used to produce dyes, spices, drugs, various chlorides and corrosion inhibitors.

What is a hydrogen chloride gas sensor?

Hydrogen chloride gas sensor is a kind of safety instrument used to detect the concentration of hydrogen chloride gas, also known as hydrochloric acid gas sensor, according to the electrochemical principle, using the measured gas in the sensor working electrode and the corresponding REDOX reaction on the electrode.

What does hydrogen chloride gas do?

1. It is understood that the role of hydrogen chloride gas is mainly for the production of dyes, spices, drugs, all kinds of chloride and corrosion inhibitors. In addition to these, there are several different production roles:

2. At 180℃ ~ 200℃ temperature and mercury salt (such as HgCl2) as catalyst conditions, hydrogen chloride and acetylene addition reaction, the formation of vinyl chloride, and then under the action of the initiator, polymerization into polyvinyl chloride.
