Common faults and solutions
Refrigeration system failure: If the test chamber is unable to maintain the required low temperature, it may be due to a failure of the refrigeration system. At this time, the pressure of the refrigeration system and the supply of refrigerant should be checked, troubleshooting and refilling refrigerant.

Failure of the heating system: If the test chamber is unable to maintain the required high temperature, it may be due to a failure of the heating system. At this time, the heating element, temperature controller and relay should be checked, troubleshooting and repair or replacement.

Humidity control system failure: If the test chamber is unable to maintain the required humidity, it may be due to a malfunction in the humidity control system. At this time, the humidity sensor, humidity controller and humidifier should be checked, troubleshooting and repair or replacement.

Control system failure: if the temperature and humidity control of the test chamber is not stable, it may be due to the failure of the control system. At this time, the temperature and humidity sensor, temperature and humidity controller and relay should be checked to troubleshoot and repair or replace.

Maintenance methods
Regular cleaning: The test chamber should be cleaned regularly to prevent the accumulation of dust and impurities. Use a clean soft cloth to wipe down the internal and external surfaces and clean the door seal to prevent leaks.

Pay attention to ventilation: the test chamber should be placed in a well-ventilated place, not near walls or other objects. Keep the temperature and humidity of the surrounding environment stable to ensure the temperature and humidity control accuracy of the test chamber.

Regular inspection: The parts and components of the test chamber should be inspected regularly to ensure that they are in normal operation. Check heating elements, refrigeration systems, humidity sensors and temperature and humidity controllers to prevent failure.

Maintenance of refrigeration system: The refrigeration system should be regularly maintained, including cleaning condensers and evaporators, checking refrigerant supply and pressure, etc. If the refrigeration system is found to be faulty, it should be repaired in time.

Regular calibration: The temperature and humidity sensors and controllers of the test chamber should be calibrated regularly to ensure their accuracy and reliability.

Common faults and solutions of constant temperature and humidity test chamber

In case of failure, maintenance and replacement of parts should be carried out in time to ensure the normal operation of the test chamber. In addition, the following are some practical tips for maintaining the constant temperature and humidity test chamber:

Before the long time test, it should be excellent to carry out the no-load test to ensure the normal operation of the test chamber.

At the end of the test, clean the test chamber, cut off the power supply and turn off all switches.

Do not place items in the inside of the test chamber to prevent affecting air circulation and affecting test results.

When placing samples in the test chamber, it should be avoided to block the air circulation port.

The test chamber should be calibrated regularly to ensure the accuracy and precision of the temperature and humidity control.

Common faults and solutions of constant temperature and humidity test chamber

When using the constant temperature and humidity test chamber, the operation specification in the operation manual should be followed to ensure the normal operation of the test chamber and extend its service life.

In short, for the maintenance and maintenance of constant temperature and humidity test chamber, regular inspection and repair should be carried out to ensure its normal operation and extend the service life. At the same time, the operator should operate in accordance with the specifications in the operation manual to avoid damage to the test chamber and affect the test results.
