How to choose need a thermometer?

Thermometer can vary, application is very wide also, so, how to choose need a thermometer? Today let's talk about according to the characteristics of all kinds of different types of thermometer. Pressure type thermometer with a bulb small volume, fast response, high sensitivity, reading the characteristics of intuitive, almost set the glass rod thermometer, bimetallic thermometer, gas pressure thermometer all advantages, it can be made into shock, anti-corrosion type, and can realize remote contact signals, heat resistance, 0 10 ma, or 4 20 ma signal. Is currently the most widely use scope, performance is one of the most comprehensive mechanical thermometer table. Bimetallic thermometer is the most widely used a thermometer, it can display temperature field, intuitive and convenient; Safe and reliable, long life; High sensitivity; 0 - The accuracy is + / - 250 c within 1%. Bimetallic thermometer is a kind of field detection instrument suitable for measurement of low temperature, can be directly used to measure the liquid, the temperature measurement of the gas pipelines and other industrial equipment. In today's more developed science and technology, electronic thermometer is more convenient, it features a lot of: (1) small volume, no space inside, thermal inertia, small measuring hysteresis; (2) readings intuitive; (3) can bend, easy to install; (4) it is the main characteristic of high accuracy, stable performance, it is not only widely used in industrial temperature measurement, and is made into standard benchmark instrument; When the choose and buy, can according to the characteristics of all kinds of thermometer, choose the required thermometer.
