Constant temperature and humidity test chamber is a kind of experimental equipment used to simulate the performance and durability test of articles under constant temperature and humidity conditions. Similar to the constant temperature and humidity chamber, the constant temperature and humidity chamber can control the set temperature and humidity conditions to test the performance and durability of the item under these conditions. Constant temperature and humidity test chamber is usually used in scientific research, production and quality management fields.

Q&A
Citirile de temperatură sau umiditate sunt inexacte.

Temperatura sau umiditatea sunt instabile.

Dispozitivul nu este încălzit sau răcit uniform.

Dispozitivul are scurgeri sau capacitatea rezervorului este insuficientă.

Care sunt problemele comune ale casetei de testare a temperaturii și umidității constante? Cum se calibra?

Metoda de calibrare
Calibrarea temperaturii: Place the thermometer in the laboratory and set the laboratory to a known temperature. După ce a așteptat ceva timp, the thermometer reading is compared with the temperature reading displayed in the experiment chamber. Dacă există o diferență, este necesară o ajustare de calibrare.

Calibrarea umidității: Use a humidity calibrator to place it in the chamber and set the chamber to a known humidity. După ce a așteptat ceva timp, the humidity calibrator reading is compared with the humidity reading displayed in the experiment chamber. Dacă există o diferență, este necesară o ajustare de calibrare.

Calibrarea uniformității echipamentului: Place several thermometers or hygrometers inside the test chamber and set the chamber to a known temperature or humidity. După ce a așteptat o perioadă de timp, comparați citirile la fiecare punct de măsurare pentru a vedea dacă sunt consecvente. Dacă există o diferență, este necesară o ajustare a calibrării uniformității.

Calibrarea capacitatii rezervorului echipamentului: Fill the tank in the laboratory with water, and record the water capacity. Then set the experimental chamber to a certain humidity, măsura pentru o perioadă de timp, apoi turnați rezervorul și înregistrați capacitatea de apă rămasă. Subtract the remaining water capacity from the previously recorded water capacity to get the amount of water used by the test chamber at this humidity. Dacă cantitatea de apă utilizată nu este în concordanță cu capacitatea din specificație, este necesară o ajustare de calibrare a capacităţii rezervorului.

In order 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
în plus, here are some ways that may help with common problems:

Temperature or humidity reading is not accurate: 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 box.

Unstable temperature or humidity: Check whether the equipment is disturbed by the external environment to ensure that there is not too much inside the test chamber

Debris or samples, ensure that the test box is well sealed. 3. 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 not too much 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 seal 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.

In cele din urma, 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, verifica performanta si starea incalzirii, răcire, Control, senzor și alte echipamente, and replace or repair the faulty parts in time. În același timp, it is recommended to follow the equipment operation manual and maintenance guidance provided by the manufacturer to maintain and maintain the test box to ensure long-term stable work.
