The constant temperature oil bath has a relatively high temperature during operation. During the operation process, attention should be paid to preventing burns. The operator should wear personal protective equipment such as heat-insulating gloves and protective glasses to avoid direct contact with the high-temperature oil liquid and the surface of the oil bath.

When adding heat transfer oil or performing other operations related to the oil bath, be careful to prevent the heat transfer oil from splashing out and scalding the skin. At the same time, ensure that the workplace is well-ventilated to avoid the accumulation of volatile gases from the heat transfer oil and cause safety accidents.

Both the standard thermometer and the calibrated thermometer are precision instruments. They should be handled with care during use to avoid violent vibration or collision, so as not to damage the internal structure of the thermometer and affect the measurement accuracy.

The insertion and removal of the thermometer should be carried out when the temperature of the oil bath is relatively stable, and the operation process should be slow to prevent the thermometer from being damaged due to a sudden change in temperature. At the same time, pay attention to keeping the temperature-sensing part of the thermometer always immersed in the heat transfer oil to avoid exposure to the air and cause measurement errors.

To ensure the accuracy of the calibration results, attention should be paid to the temperature uniformity in the constant temperature oil bath. During the heating process of the oil bath, the temperature in each part of the oil bath can be made as uniform as possible by appropriately adjusting the stirring speed and the distribution of heating power.

When measuring the temperature, if possible, multiple thermometers can be inserted at different positions in the oil bath to measure and compare the temperature differences at each point. If the temperature uniformity is found to be poor, it should be timely checked whether the stirring device and heating element of the oil bath are working normally, and if necessary, repair or adjust them.

The calibration cycle of the constant temperature oil bath should be comprehensively determined according to factors such as its usage frequency, accuracy requirements, and equipment stability. Generally, it is recommended to calibrate regularly, such as at least once a year. For the constant temperature oil bath with frequent use or high accuracy requirements, the calibration cycle can be appropriately shortened to ensure that its measurement accuracy always meets the work requirements.
