What are the environmental requirements for microhardness testing HMV?

Microhardness testers (HMV) have certain requirements for the environment during testing; good environmental conditions help ensure the accuracy of test results and the normal operation of the equipment.
Regarding temperature, it is generally required that the testing environment temperature be maintained between 20°C-25°C, with a small range of temperature fluctuation. This is because temperature changes may affect the hardness performance of the material and also have a certain impact on the precision of the equipment, such as causing thermal expansion and contraction of components like the loading system and optical system, thereby introducing errors.
Regarding humidity, the environmental humidity should be controlled between 40%-60%; excessively high humidity may cause moisture on the sample surface, affecting the clear observation and measurement of the indentation; excessively low humidity may generate static electricity, causing damage to the electronic components of the equipment.
In addition, the testing environment should be kept clean and free of vibration, avoiding dust and debris from entering the interior of the equipment, which would affect its performance and service life.
