Yüksek ve düşük sıcaklık odası, malzemeleri simüle etmek için kullanılan bir tür dayanıklılık test ekipmanıdır., elektronik, kimyasal, yiyecek, medicine and other products under high and low temperature environment. Here are some common problems you may encounter and calibration methods:

Q&A
The temperature reading is inaccurate.

The temperature is unstable.

The device is not evenly heated or cooled.

The device is leaking or the tank capacity is insufficient.

An error occurred in program operation.

Calibration method
Temperature calibration: Place the thermometer in the high and low temperature box and set the high and low temperature box to a known temperature. After waiting for some time, compare the thermometer reading with the temperature reading displayed in the high and low temperature chamber. If there is a difference, a calibration adjustment is required. Calibration can be done by adjusting the temperature calibration parameters in the controller.

Equipment uniformity calibration: place several thermometers inside the high and low temperature chamber and set the high and low temperature chamber to a known temperature. After waiting for a period of time, compare the readings at each measurement point to see if they are consistent. If there is a difference, a uniformity calibration adjustment is required. It can be achieved by adjusting the working mode and position of heating, cooling and fans, as well as adjusting the position of items inside the high and low temperature box.

Equipment tank capacity calibration: Fill the tank in the high and low temperature box with water, and record the water capacity. Then set the high and low temperature box to a certain temperature, measure for a period of time, and then pour out the tank and record the remaining water capacity. Subtract the remaining water capacity from the previously recorded water capacity to get the amount of water used by the high and low temperature tank at that temperature. If the amount of water used is not consistent with the capacity in the specification, a tank capacity calibration adjustment is required. It can be calibrated by adjusting the tank capacity parameters in the controller.

Size hatırlatıyoruz: the high and low temperature box needs to be calibrated and maintained regularly. Aynı zamanda, it is necessary to regularly clean the inside of the equipment, check the performance and condition of the heating, soğutma, kontrol, sensors and other equipment, and timely replace or repair the faulty parts. Ek olarak, it is recommended to maintain the device according to the operation manual and maintenance guidance provided by the manufacturer to ensure long-term stable operation of the device.

Matters needing attention
In the process of using a high and low temperature box, the following points need to be noted:

Arrange the position of the sample to ensure that the sample can receive uniform temperature distribution.

2. Do not accumulate too much debris or samples inside the high and low temperature box to avoid affecting the operation of the equipment and the accuracy of the data.

Gerçek ihtiyaçlara göre, the temperature range and accuracy of the high and low temperature chamber are reasonably selected to avoid inaccurate test data due to equipment parameter mismatch.

Testten önce, pre-heat or pre-cool the equipment to ensure that the required temperature conditions can be achieved.

In the process of using the equipment, temperature changes and test data are recorded in time, and analyzed and processed according to needs.

Kısacası, the high and low temperature box is a commonly used test equipment, but it is necessary to pay attention to the use and maintenance of the equipment during use to ensure the stability of the equipment and the accuracy of the test data.
