Electrochemical C2H4O gas sensor Introduction

Electrochemical C2H4O gas sensor is a gas detection instrument which uses electrochemical detection principle to detect the concentration of ethylene oxide gas in the air. Electrochemical C2H4O gas sensor can detect ethylene oxide gas in the concentration range of 0-100ppm or 0-500ppm, with good selectivity, stability, built-in temperature sensor for temperature compensation. The ethylene oxide sensor also has a digital output, easy to use, is a mature electrochemical detection technology and sophisticated circuit design, design and manufacture of ethylene oxide gas module. It is widely used in various occasions and equipment that need gas detection.

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 ethylene oxide?

Ethylene oxide, an organic compound with the chemical formula C₂H₄O, is a toxic carcinogen previously used to make fungicides. Ethylene oxide is flammable and explosive, not easy to transport long distance, so there is a strong regional. It is widely used in washing, pharmaceutical, printing and dyeing industries. It can be used as starting agent for cleaning agent in chemical industry.

What is an ethylene oxide gas sensor?

Ethylene oxide sensor is suitable for all kinds of environment and special environment of volatile organic compounds ethylene oxide gas concentration and leakage, hazardous site operation safety has a warning role, this instrument adopts the electrochemical sensor and microcontroller technology imported, with stable signal, high precision, good repeatability and other advantages.

What are the uses of ethylene oxide?

Most of the ethylene oxide is used to make other chemicals, mainly ethylene glycol. The main end use of ethylene glycol is the production of polyester polymer, also used as automotive coolant and antifreeze. Secondly, it is used to produce ethoxy compounds, ethanolamine, ethylene glycol ether, ethylamine, diethylene glycol, triethylene glycol, polyethylene glycol, hydroxyethyl cellulose, choline chloride, glyoxal, ethylene carbonate and other downstream products. Ethylene OXIDE IS mainly used IN the manufacture of ethylene glycol (polyester fiber raw material), synthetic detergent, non-ionic surfactant, antifreeze, emulsifier and ethylene glycol products, also used in the production of plasticizers, lubricants, rubber and plastics.
