The high-low Temperature Test Chamber is a kind of experimental equipment that can provide high temperature or low temperature environment, which is used to test the performance and durability of items at different temperatures. The equipment can simulate various extreme environments, such as high temperature, low temperature, humid heat, etc., so as to conduct comprehensive and systematic testing and evaluation of items.
The high-low temperature test box is usually composed of a heating system, a refrigeration system, a control system, a working room, and an inlet and outlet device. Heating and cooling systems heat or cool the air to maintain a set high or low temperature environment. The control system can precisely control parameters such as temperature, humidity, and time to meet the needs of different experiments. The design and construction of the studio and the feeding and discharging device will also vary according to different usage scenarios and experimental requirements.
common problem
The temperature reading is inaccurate.
The temperature is unstable.
The device is heating or cooling unevenly.
The device is leaking or the Water Tank is insufficient.
An error occurred in program operation.
Solution
Temperature calibration: Place the thermometer in the high-low temperature test box, and set the test box to a known temperature. After waiting for a period of time, compare the thermometer reading with the temperature reading displayed by the Test Chamber. If there is a difference, a calibration adjustment is required. Calibration can be performed by adjusting the temperature calibration parameters in the controller.
Equipment uniformity calibration: Place several thermometers inside the test box and set the test box to a known temperature. After waiting for a period of time, compare whether the readings of each metering point are consistent. If there is a difference, a uniformity calibration adjustment is required. This can be done by adjusting how and where the heating, cooling and fans work, and by adjusting the position of items inside the chamber.
Equipment Water Tank capacity calibration: fill the Water Tank in the test box with water, and record the water capacity. Then set the test box to a certain temperature, after measuring for a period of time, pour out the Water Tank and record the remaining water capacity. Subtract the previously recorded water volume from the remaining water volume to get the amount of water used by the chamber at that temperature. If the amount of water used is inconsistent with the capacity in the specification, a Water Tank capacity calibration adjustment is required. It can be calibrated by adjusting the Water Tank capacity parameter in the controller.
North and South Chao reminds you: high-low Temperature Test Chambers need to be calibrated and maintained regularly. At the same time, it is necessary to regularly clean the interior of the equipment, check the performance and condition of heating, cooling, control, sensors and other equipment, and replace or repair problematic parts in time. In addition, it is recommended to carry out maintenance according to the operation manual of the equipment and the maintenance instructions provided by the manufacturer to ensure the long-term stable operation of the equipment.
Precautions for use
In the process of using the high-low temperature test box, the following points should be paid attention to:
Reasonably arrange the placement of the samples to ensure that the samples can be subjected to a uniform temperature distribution.
Do not accumulate too much sundries or samples inside the test box to avoid affecting the operation of the equipment and the accuracy of the data. 3. According to actual needs, reasonably select the temperature range and accuracy of the test box to avoid inaccurate test data due to mismatching equipment parameters.
Before testing, preheat or precool the equipment to ensure that the equipment can reach the required temperature conditions.
During the use of equipment, record temperature changes and test data in time, and analyze and process them as needed.
In short, the high-low Temperature Test Chamber is a commonly used environmental simulation 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.
