Constant temperature and humidity test chamber is a kind of test equipment used to simulate different temperature and humidity environmental conditions. Here are some common problems you may encounter and calibration methods:

П&А
Temperature or humidity readings are inaccurate.

The temperature or humidity is unstable.

Уређај није равномерно загрејан или хлађен.

Уређај цури или је капацитет резервоара недовољан.

Метода калибрације
Калибрација температуре: Place the thermometer in the test chamber and set the chamber to a known temperature. После извесног времена, the thermometer reading is compared with the temperature reading displayed in the test chamber. Ако постоји разлика, потребно је подешавање калибрације.

Humidity calibration: Use a humidity calibrator to place it in the test chamber and set the test chamber to a known humidity. После извесног времена, compare the humidity calibrator reading with the humidity reading displayed in the test chamber. Ако постоји разлика, потребно је подешавање калибрације.

Калибрација униформности опреме: Place several thermometers or hygrometers inside the test chamber and set the test chamber to a known temperature or humidity. Након чекања одређеног временског периода, упоредите очитавања на свакој тачки мерења да видите да ли су конзистентна. Ако постоји разлика, потребно је подешавање калибрације униформности.

Калибрација капацитета резервоара опреме: Fill the tank in the test box with water and record the water capacity. Then set the test chamber to a certain humidity, мера за одређено време, а затим излити резервоар и забележити преостали капацитет воде. Subtract the remaining water capacity from the previously recorded water capacity to obtain the amount of water used by the test chamber at this humidity. Ако количина коришћене воде није у складу са капацитетом у спецификацији, потребно је подешавање калибрације капацитета резервоара.

To ensure accurate and reliable test results, the constant temperature and humidity test chamber needs to be calibrated and maintained regularly. Calibration and maintenance should be carried out by experienced technicians and in accordance with the equipment’s operating manual.

Common problem solving
Додатно, here are some ways that may help with common problems:

Inaccurate temperature or humidity reading: Check whether the sensor is damaged or needs to be replaced, check whether the sensor is in an appropriate position, and ensure that the sensor is the same temperature or humidity as the test chamber.

Unstable temperature or humidity: Check whether the equipment is disturbed by the external environment, ensure that there is not too much debris or samples inside the test chamber, and ensure that the test chamber is well sealed.

Uneven heating or cooling of the equipment: check whether the heating or cooling components are uniform, check whether the equipment needs to be cleaned or replaced, ensure that there is no excessive debris or samples inside the test box, and ensure that the test box is well sealed.

Equipment leakage or insufficient tank capacity: check whether the tightness of the test box is good, check whether the tank needs to be cleaned or replaced, ensure that there is not too much debris or samples inside the test box, and replenish the water in the tank in time.

Коначно, in order to maintain the performance and reliability of the test chamber, regular maintenance and maintenance are required. It is recommended to clean the inside of the test chamber regularly, проверите перформансе и стање грејања, хлађење, контролу, сензора и друге опреме, and replace or repair the faulty parts in time. Истовремено, it is recommended to follow the equipment operation manual and maintenance instructions provided by the manufacturer to maintain and maintain the test chamber for a long time.
