The programmable constant temperature and humidity test chamber is a kind of high precision constant temperature and humidity test equipment, which is often used in laboratories and production lines in the fields of materials, elektronika, chemiczny, żywność, medicine and so on. Oto kilka typowych problemów, które możesz napotkać, oraz metody kalibracji:

Q&A
Odczyty temperatury lub wilgotności są niedokładne.

Temperatura lub wilgotność są niestabilne.

Urządzenie nie jest równomiernie nagrzewane lub chłodzone.

Urządzenie przecieka lub pojemność zbiornika jest niewystarczająca.

An error occurred in program operation.

Metoda kalibracji
Kalibracja temperatury: Umieść termometr w komorze testowej i ustaw komorę na znaną temperaturę. Po odczekaniu pewnego czasu, the thermometer reading is compared with the temperature reading displayed in the test chamber. If there is a difference, a calibration adjustment is required. Calibration can be done through program Settings or by adjusting the sensor circuit.

Humidity calibration: Use a humidity calibrator to place it in the test chamber and set the test chamber to a known humidity. Po odczekaniu pewnego czasu, compare the humidity calibrator reading with the humidity reading displayed in the test chamber. If there is a difference, a calibration adjustment is required. Calibration can be done through program Settings or by adjusting the sensor circuit.

Equipment uniformity calibration: Place several thermometers or hygrometers inside the test chamber and set the test chamber to a known temperature or humidity. 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. Calibration can be done through program Settings or by adjusting the sensor position.

Equipment tank capacity calibration: Fill the tank in the test box with water and record the water capacity. Then set the test chamber to a certain humidity, 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 obtain the amount of water used by the test chamber at this humidity. 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 through program Settings or by adjusting the tank capacity.

Przypominamy: the programmable constant temperature and humidity test chamber needs to be calibrated and maintained regularly, and the program needs to be updated and maintained. Program error is one of the common problems. It is necessary to maintain the program in time to ensure the correctness and stability of the program. Ponadto, it is recommended to follow the equipment’s operating manual and

Maintenance guidance provided by the manufacturer to carry out maintenance, regularly clean the inside of the equipment, check the performance and condition of heating, chłodzenie, kontrola, sensors and other equipment, timely replacement or repair of faulty parts. Ponadto, you are advised to power off the device before maintenance and wait until the device cools down to ensure safety.

Precautions for use
In the process of using the programmable constant temperature and humidity test chamber, the following points should also be noted:

Reasonable arrangement of sample placement, to ensure that the sample can be subjected to uniform temperature and humidity distribution.

Do not accumulate too much debris or samples inside the test chamber to avoid affecting the operation of the equipment and the accuracy of the data.

According to actual needs, the temperature and humidity range and accuracy of the test chamber should be reasonably selected to avoid inaccurate test data due to mismatch of equipment parameters.

Przed testem, pre-heat or pre-cool to ensure that the equipment can meet the required temperature and humidity conditions.

In the process of using the equipment, the temperature and humidity changes and test data are recorded in time, and analyzed and processed as required.

W skrócie, the constant temperature and humidity test chamber and the programmable constant temperature and humidity test chamber play an important role in the laboratory and production line, ale w tym samym czasie, attention needs to be paid to the use and maintenance of the equipment to ensure the stability of the equipment and the accuracy of the test data.
