Electrochemical HCN gas sensor Introduction
Electrochemical HCN gas sensor is a gas detection instrument that uses electrochemical principle to detect hydrogen cyanide gas in the air. Electrochemical HCN gas sensor adopts three-electrode structure design, the product performance is significantly improved, has good selectivity, stability. Electrochemical hydrogen cyanide sensor also built-in temperature sensor, temperature compensation, with digital output, easy to use. It is a universal gas module designed and manufactured by combining mature electrochemical detection technology with excellent circuit design.

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 cyanide gas?
Hydrogen cyanide is an inorganic compound, HCN, in its standard state, liquid. Hydrogen cyanide is easy to be evenly dispersed in the air, and can be burned in the air. When the content of hydrogen cyanide in the air reaches 5.6%~12.8%, it is explosive. Hydrocyanic acid is highly toxic. The clinical manifestations of acute hydrogen cyanide poisoning are obvious bitter almond taste in the exhaled breath of patients, and the mild poisoning mainly shows chest tightness, palpitation, rapid heart rate, headache, nausea, vomiting and blurred vision.
The use of hydrogen cyanide
Appearance and Properties: Colorless gas or liquid, bitter almond taste.
Main Applications: Used in the manufacture of acrylonitrile and acrylic resins and pesticides.
Dangerous characteristics: this product is flammable, its vapor and air can form an explosive mixture, in case of open fire, high heat energy caused by combustion explosion; Long-term placement due to moisture and polymerization, the polymer itself has autocatalytic effect, can cause explosion.
What is a hydrogen cyanide gas detector?
Hydrogen cyanide gas detector, using high precision, long life of imported electrochemical hydrogen cyanide sensor, accurate detection work, widely used in various chemical plants.
