the safety function of the gas detector is obvious, and the national inspection of security inspection is also increased accordingly. in the future, more and more chemical manufacturers will buy and use gas detectors. for the uneven gas detectors on the market, what aspects can we consider?

1, whether the production qualification is complete;

2, whether the identification coefficient is standardized.

3, brand and certificate model.

4, after-sales service and guarantee.

First of all, let's analyze it from the perspectives of "whether the product qualification is complete" and "whether the product nameplate coefficient is standardized.

Whether the product qualification is complete;

For example, Yiyuntian Company has carried out a lot of research and development and innovation in products. All products have passed the authorization of the State Administration of Work Safety, the national testing and inspection agency and the national legal measurement unit explosion-proof certification.

Yiyuntian has more than 50 safety and explosion-proof products in the two major series of industry and coal mines, which meets the one-stop demand for safe production.

Whether the nameplate coefficient meets the specifications.

the nameplate of the gas detector is just like a person's ID card, recording all kinds of information of this alarm, so that users can clearly understand the functions and parameters of the equipment. Therefore, the nameplate of the gas detector must be specified in detail, and the product number, explosion-proof certificate number and explosion-proof mark must be recorded on the nameplate.

Many manufacturers do not attach importance to the use of product nameplates on the surface, in fact, some non-standard marks on the nameplate are used to cover up the quality and safety of the equipment.

Some non-standard nameplate graphics on the market are listed below.

analysis:

(1) the national production safety law stipulates that the product nameplate for inspecting gas detectors must have explosion-proof mark, explosion-proof certificate number and production number. there is no mark of the first two in the figure. the mark of the nameplate is not standard enough, it is difficult to understand the product information from the nameplate, and the product concept is vague.

on the marking of the measuring range, the nameplate only writes the routine and does not mark the specific data, which is very inconvenient for some new customers, and the average person does not know how the manufacturer's routine is defined, and the data is not transparent enough.
