Which brand is good for combustible gas detectors?
Thread Content
For petrochemical projects, acrylic acid, butyl acrylate, and acid purification units – which combustible gas detector is the best choice? RAE? DRAGER?
I’ve used those from Wuxi Shihe, and those from Yanshan in Beijing – both work fine. These products are all very good, and there are many manufacturers of them
DRAGER’s quality is quite good; it’s just too expensive
Our factory uses Anxinke from Sichuan, and it works fine
Imported Delge, Corey, and Xinyuzhou; domestic brands such as Huade, Meisan, and Tean
Anxinke, Anxinke. . How can one believe it? . . . . Hehehe. . . . . The most commonly used in factories is this Unicore, along with its alarm control system. No problems were detected in the previous years, but recently, a large number of units in use have revealed a rather basic issue: as soon as the temperature drops below minus 5 or 6 degrees, these alarms show error codes E001 or E002. The solution is to remove and reinsert the sensor at the installation site, and then the problem goes away. Yet such E001 error alerts occur whenever the temperature drops – how can this be trusted? . . .
Generally, a temperature of minus 20 degrees is fine
GreenTone is just average; it has many malfunctions
