Thermometer factory group, a surface protection and use of the temperature and pressure

Nowadays in many chemical plants are used to a body surface temperature and pressure, the device can not only test pressure can also test the temperature at the same time, the function is very powerful, so how to protect in the use? 1, the thermometer factory group, a surface appearance, temperature and pressure at the time of use must ensure that it is straight, it is best to use when installation of 17 mm wrench, pull (thread do tighten processing, for watchcase, don't tough twist, in the process of transporting, appear not to knock against. 2, for the use of the environment, temperature and pressure of a surface surrounding the use of the environment temperature must be - Range from 25 to 55 ℃, regardless of the temperature is too high, or the temperature is too low, when using can create table error or even damage. 3, choose the appropriate range, in the process of use to avoid overpressure caused by the pressure indicator is not zero. 4, in the end, for the use of a surface model, temperature and pressure to do between the upper limit for anywhere between a third and two-thirds.
