Manufacturers of gas detectors
Thread Content
Does anyone know of any good manufacturers of gas detectors? How are Dräger’s gas detectors? What’s the cost-performance ratio?
1. Flammable, suitable for catalytic combustion; domestic and imported versions have similar performance, with domestic ones being cheaper; it is recommended to use domestic ones； 2. For infrared therapy, I’ve used Dräger, and the results are good ； 3. Flammable counter-type DETRONICS and Dräger models are available at different distances; care should be taken when selecting the appropriate model. These products are relatively expensive and come with SIL certification ； 4. Toxic gases: Organic gases can cause cross-interference with the detectors, especially in those designed for detecting toxic gases in the PPM range. Given the increasingly strict safety requirements and provided that the budget permits, imported detectors are considered as they offer better performance; at the same time, the cost of replacing the detectors in the future is taken into account, so the detectors are quoted separately in the bidding process.
Delge is expensive. Many domestic manufacturers use imported probes, which are cheaper; they can be considered if the requirements aren’t too high. There are also many good manufacturers these days, such as Henan Hanwei and Juguang Technology, and there are some excellent manufacturers in Shenzhen as well.
Shenzhen Te’an, Anxinke, Hanwei – all are quite good
Wuxi Meisan, Shenzhen Tean, Henan Hanwei, Honeywell
Delge’s products are definitely a good option. The problem is, does each unit cost over ten thousand yuan? Do you have that much money? In China, only companies like Shenzhen Te’an and Beijing Huàde offer relatively better products at the moment
