The temperature and humidity control box is a kind of equipment used to control the humidity and temperature of the environment, which is often used in pharmaceutical, food, chemical, electronic and other industries. Here are some common problems you may encounter and how to calibrate them:
common problem
Inaccurate temperature or humidity readings.
Unstable temperature or humidity.
The device is heating or cooling unevenly.
The device is leaking or the Water Tank is insufficient.
An error occurred in program operation.
Calibration method
Temperature or Humidity Calibration: Place a thermometer or hygrometer in the temperature and Humidity Chamber, and set the temperature and Humidity Chamber to a known humidity or temperature. After waiting for a period of time, compare the thermometer or hygrometer reading to the temperature or humidity reading displayed by the humidifier. If there is a difference, a calibration adjustment is required. Calibration can be done by adjusting the temperature or humidity calibration parameters in the controller.
Equipment uniformity calibration: Place several thermometers or hygrometers inside the temperature and humidity control box, and set the temperature and humidity control box to a known humidity or 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 climate chamber.
Equipment Water Tank capacity calibration: fill the Water Tank in the temperature and humidity control box with water, and record the water capacity. Then set the temperature and humidity control box to a certain humidity or temperature, after measuring for a period of time, pour out the Water Tank and record the remaining water capacity. Subtract the previously recorded water capacity from the remaining water capacity to obtain the water volume used by the temperature and humidity control box at the humidity or 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.
The north and south tides remind you: the temperature and humidity control box needs 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.
In the process of using the temperature and humidity control box, you also need to pay attention to the following points:
Reasonably arrange the placement of samples to ensure that the samples can be subjected to uniform temperature and humidity distribution.
Do not accumulate too much debris or samples inside the temperature and humidity control box, so as to avoid affecting the operation of the equipment and the accuracy of the data.
According to actual needs, reasonably select the temperature or humidity range and accuracy of the temperature and humidity control box to avoid inaccurate test data due to mismatching equipment parameters.
Before testing, it is best to preheat or precool the equipment to ensure that the equipment can reach the required temperature and humidity conditions.
During the use of the equipment, the humidity and temperature changes and test data are recorded in time, and analyzed and processed as needed.
In short, the temperature and humidity control box is a commonly used device to control the humidity and temperature of the environment, but it is necessary to pay attention to the use and maintenance of the device during use to ensure the stability of the device and the accuracy of the test data.
