A temperature calibration laboratory has strict requirements for environmental conditions. The primary one is temperature stability. The ideal laboratory environment should be able to control temperature fluctuations within a very small range. Usually, it is required that the temperature change does not exceed ±0.5℃ within a specific period, such as 24 hours. This requires the installation of a high-precision air-conditioning system or temperature adjustment equipment, which has good temperature control accuracy and rapid response ability to deal with the impact of external environmental changes.
Humidity control cannot be overlooked either. Excessively high humidity may cause problems such as equipment rusting and short circuits, while excessively low humidity may generate static electricity and interfere with the normal operation of calibration instruments. Generally, the laboratory humidity should be maintained within a relative humidity range of 40% - 60%. For this purpose, humidity adjustment devices such as humidifiers and dehumidifiers should be installed, and humidity sensors should be equipped for real-time monitoring and feedback control.
In addition to temperature and humidity, the laboratory also needs to consider air cleanliness. Dust and impurities may adhere to the sensors or other key components of temperature calibration equipment, affecting measurement accuracy. Therefore, an air filtration system should be installed to filter out tiny particles in the air and ensure that the laboratory air meets a certain cleanliness standard, such as the ISO 8 cleanliness standard, to maintain the normal operation of the equipment and the accuracy of calibration.
Moreover, the lighting conditions in the laboratory should also be appropriate, avoiding strong light direct irradiation or too dim light that may cause inconvenience for operators to read data and operate equipment. Good environmental control is the fundamental guarantee for the normal operation of a temperature calibration laboratory and the assurance of calibration quality.
