Is the thermometer subject to mandatory inspection? What is its inspection cycle? Which department should conduct the inspection?

Thermometers do not fall within the scope of compulsory inspection. The inspection cycle is generally 12 months and can be verified by qualified inspection departments, such as quality and technical supervision departments.

Whether the thermometer is subject to mandatory inspection depends on where it is placed. If it is on a test/measuring instrument, it should be subject to mandatory inspection. If it is just on general equipment, there is no need for mandatory inspection.

When the thermometer is used as a safety accessory, it is a compulsory inspection equipment and shall be inspected by a statutory agency.
