Heating and Humidity Chamber FAQ and solutions

Humidity chamber is a commonly used test equipment, which is used to simulate the heat resistance, moisture resistance, corrosion resistance and other properties of items under various environmental humidity and temperature conditions. Here are some common issues you may encounter and how to fix them:

common problem

1. Inaccurate temperature or humidity readings.

2. Unstable temperature or humidity.

3. The device is heating or cooling unevenly.

4. The device is leaking or the Water Tank is insufficient.

5. An error occurred in program operation.

Solution

1. Temperature or Humidity Calibration: Place a thermometer or hygrometer in the humid heat chamber and set the humid heat chamber to a known humidity or temperature. After waiting for a period of time, compare the thermometer or hygrometer reading with the temperature or humidity reading displayed by the humid heat chamber. 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.

2. Calibration of equipment uniformity: Place several thermometers or hygrometers inside the humid heat box, and set the humid heat 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 humid heat chamber.

3. Equipment Water Tank capacity calibration: fill the Water Tank in the humid heat tank with water, and record the water capacity. Then set the humid heat 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 get the amount of water used by the humid heat chamber at that 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 northern and southern tides remind you: the humid heat 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 long-term stable operation of the equipment.

Precautions

In the process of using the humid heat box, you need to pay attention to the following points:

1. Reasonably arrange the placement of samples to ensure that the samples can be subjected to uniform temperature and humidity distribution.

2. Do not accumulate too much sundries or samples inside the humid heat box, so as not to affect the operation of the equipment and the accuracy of the data.

3. According to actual needs, reasonably select the temperature or humidity range and accuracy of the humid heat chamber to avoid inaccurate test data due to mismatching equipment parameters.

4. Before testing, it is best to preheat or precool the equipment to ensure that the equipment can reach the required temperature and humidity conditions.

5. 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 humid heat 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.
