magnetic flap thermometer in addition to the basic performance advantages, generally in the use of temperature time and they are widely used in industrial production in chemical industry of the corrosive medium level measurement requirements, it is very important for the masses of users. According to the material on the market at present four fluorine with stainless steel inner liner, four fluorine, 316 l stainless steel, stainless steel inner spray polypropylene ( PP) Or PVC ( PVC) Wait for a few kinds. Strongest anticorrosion performance is the most widely type stainless steel lined with ptfe, but the price of stainless steel lining four fluorine thermometer is highest, because four fluorine material price is high and not only at high temperatures can produce poisonous gas, production process requirement is high, if not special needs, and working temperature below 90 ℃, suggest to choose PP or PVC type, it can be used in hydrochloric acid, sulfuric acid, nitric acid, sodium chloride, sodium hydroxide, such as acid, alkali liquid, half price is cheaper than four fluorine lining, the use of the same effect but let you of the investment cost is greatly reduced, the industry is very competitive, if slightly slow development speed, will be left behind.

the development of measuring instrument and meter industry also restricted by the objective environment. A heavy taxes; 2 departments to develop measurement products industry important understanding insufficiency, support is not enough; Three lack of support for the development of national industry procurement policy. Magnetic flap with the ordinary thermometer thermometer has very obvious advantages, the life has very obvious increase, this is one of the biggest characteristic, measured by the general environment, has strong corrosion, high temperature, fully sealed environment and so on.
