How to choose a safe and reliable gas detector and reactor oxygen content analyzer?
There are many manufacturers of gas detectors. The gas detectors produced by some businesses are explosion-proof and have no intrinsically safe and explosion-proof function, and they cannot pass the accuracy test from the National Formal Metrology Institute, so the appearance inspection certificate is used. The product accuracy testing certificate is used, and some merchants purchase the certificate from some loosely managed testing institutions in other places, and some merchants directly forge the testing certificates of some loosely managed testing institutions. If consumers buy such products, use In high-risk places, it will bring security risks.
Because of price and other factors, most products in the market currently use flameproof explosion-proof technology, and only a few products use intrinsically safe explosion-proof technology, all of which are explosion-proof. What is the difference between the two?
The explosion-proof type has the requirements of explosion-proof performance. It isolates the explosive and flammable mixture through the shell of the equipment. When the short-circuit components inside the equipment are damaged, electric sparks are generated or when the flammable and explosive mixture (gas However, due to the isolation and cooling of the shell, the explosion is prevented from extending outside the shell, thereby achieving an explosion-proof effect.
The intrinsically safe type is the intrinsically safe type. It starts from limiting energy and reliably limits the voltage and current in the circuit within an allowable range to ensure that the equipment is in normal operation or short-circuit components are damaged. The electric spark and thermal effect of the device will not cause the explosion of the dangerous gas that may exist around it, so the intrinsically safe explosion-proof type is the explosion-proof type of safety level.
So, how do we choose a regular, safe and reliable gas detector?
First of all, it depends on whether the manufacturer has an explosion-proof certificate. The purpose of explosion-proof certification is to eliminate the dangerous factors of facilities in explosion-hazardous places. Therefore, the gas detector only has the function of intrinsically safe explosion-proof and can be used in dangerous places only if it has issued the certification certificate issued by the organization.

Secondly, high measurement accuracy is also a requirement for gas detectors. The gas detector developed and produced by Nanjing Safeme Technology uses imported first-line big brand sensors. After our company's unique compensation algorithm and multi-stage standard gas calibration, it has the characteristics of sensitive response, high measurement accuracy, strong anti-interference, small size, Light weight, high safety and reliability, after measurement and verification, it has obtained the metrological verification certificate of Jiangsu Provincial Market Supervision and Administration Bureau, and has credibility.
How to choose a safe and reliable gas detector?
High-risk occasions are closely related to people's life safety. From the perspective of safety, you should choose to buy intrinsically safe explosion-proof gas detectors produced by regular manufacturers.
