The equipment maintenance and care in a temperature calibration laboratory is a crucial step to ensure the long-term stable operation and calibration accuracy of the equipment.
For core calibration equipment, such as high-precision thermometers and temperature calibrators, regular calibration is an important part of maintenance. Calibrating according according to the specified calibration cycle can not only verify the accuracy of the equipment but also detect any possible drift or malfunction of the equipment in a timely manner. Between two calibrations, daily performance checks should be carried out, including checking whether the display of the equipment is normal, whether the button operation is sensitive, and whether the connecting wires are loose. For example, before using it every day, observe whether there is any abnormal display on the screen of the high-precision thermometer and check whether each interface of the temperature calibrator is firmly connected.
The cleaning and maintenance of the equipment cannot be ignored either. Impurities such as dust and oil may affect the heat dissipation, electrical performance, and measurement accuracy of the equipment. Regularly use clean and soft tools and cleaners to clean the surface of the equipment. For internal components such as circuit boards, compressed air can be used for blowing and cleaning, but be careful to avoid damaging precision elements. For example, clean the outer shell of the constant temperature bath every month and clean the internal circuit board of the temperature calibrator with compressed air once a quarter (under the guidance of a professional).
The environmental control equipment plays an important role in maintaining a stable environment in the laboratory, and its maintenance is also crucial. The air-conditioning system should be regularly checked for filters and replaced in a timely manner to ensure good ventilation; the humidity adjustment equipment should be checked for normal humidification and dehumidification functions, and the water tank and humidifying elements should be cleaned regularly. For example, check the air-conditioning filter every two months and clean the water tank of the humidity adjustment equipment every six months.
In addition, for the wearing parts and consumables of the equipment, an inventory management system should be established, and a certain number of spare parts should be reserved in advance so that they can be replaced in a timely manner when the parts are damaged, reducing the equipment downtime. At the same time, a detailed record of the maintenance history of the equipment should be kept, including maintenance time, maintenance content, replaced parts, etc. This helps to analyze the operating status of the equipment and predict possible malfunctions, providing a basis for formulating a more reasonable maintenance plan.
