|product name:||Aniline gas alarm|
|Measurement object:||Aniline in the air|
Aniline is also called Anilin, Anilin oil, aminobenzene, colorless oily liquid. Aniline is one of the most important amines. It is mainly used in the manufacture of dyes, drugs, resins, and can also be used as a rubber vulcanization accelerator. It can also be used as a black dye by itself. Its derivative, methyl orange, can be used as an indicator for acid-base titration. Aniline gas alarm is a fixed type instrument that can continuously detect the concentration of aniline gas in the working environment. Aniline gas alarm is a natural diffusion method to detect the gas concentration. It uses imported electrochemical sensors with excellent sensitivity and excellent repeatability. It will activate the audible and visual alarm signal or drive the exhaust system immediately after the preset alarm point; International Standard 4- The 20mA signal can be directly connected to the factory DCS system or RS485 digital signal to connect to the factory host computer; the instrument uses embedded micro-control technology, which is simple to operate, complete in function, high in reliability, and the overall performance of the machine ranks domestically leading. Aniline gas alarm has the characteristics of excellent performance, stable and reliable operation, and convenient installation and maintenance. It greatly meets the requirements of industrial field safety monitoring for high reliability and stable operation of equipment; it has been widely used in petroleum, chemical, metallurgical, refining, Gas transmission and distribution, biochemical medicine and water treatment industries.
