Abstract

The invention discloses an anti-explosion hygrothermograph which comprises a shell, a temperature and humidity circuit board is arranged in the shell, a temperature probe and a humidity probe are arranged on the outer side of the shell and are connected with the temperature and humidity circuit board through wires respectively, an exhaust hole is formed in one side of the shell, an exhaust valve is arranged at the exhaust hole. An inflation box is arranged on one side of the shell and communicated with the shell through an inflation pipe. The anti-explosion hygrothermograph has the advantages that the circuit board of the explosion-proof hygrothermograph is fixed in the shell, generated electric sparks cannot be transmitted to the outside, the explosion-proof hygrothermograph is suitable for being used in flammable and explosive places, cooling is very convenient, the internal temperature is kept appropriate, the anti-explosion hygrothermograph is suitable for normal work of the internal circuit board, and the service life is indirectly prolonged.

Description

technical field [0001] The invention relates to the technical field of thermo-hygrometers, in particular to an explosion-proof thermo-hygrometer. Background technique [0002] The temperature and humidity meter is used to measure the temperature and humidity of the environment to determine the environmental conditions of product production or storage. It is also used in people's daily life. The application is more extensive. However, the thermo-hygrometer in the prior art can only be used in common occasions, and there are potential safety hazards when used in inflammable and explosive places. Contents of the invention [0003] The object of the present invention is to propose an explosion-proof thermo-hygrometer in order to solve the shortcomings in the prior art. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] An explosion-proof thermometer and hygrometer, including a housing, a temperature and h...
