The constant temperature and humidity Test Chamber is an experimental equipment used to simulate the performance and durability tests of items under constant temperature and humidity conditions. Similar to constant temperature and Humidity Chambers, constant temperature and Humidity Chambers can control set temperature and humidity conditions to test the performance and durability of items under these conditions. Constant temperature and humidity Test Chambers are usually used in fields such as scientific research, production and quality management.
common problem
Inaccurate temperature or humidity readings.
Unstable temperature or humidity.
The device is heating or cooling unevenly.
The device is leaking or the Water Tank is insufficient.
Calibration method
Temperature Calibration: Place the thermometer in the chamber and set the chamber to a known temperature. After waiting for a period of time, compare the thermometer reading with the temperature reading displayed by the Test Chamber. If there is a difference, a calibration adjustment is required.
Humidity Calibration: Use a humidity calibrator to place it in the chamber and set the chamber to a known humidity. After waiting for a period of time, compare the humidity calibrator reading with the humidity reading displayed by the chamber. If there is a difference, a calibration adjustment is required.
Equipment uniformity calibration: Place several thermometers or hygrometers inside the test box, and set the test box to a known temperature or humidity. 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.
Equipment Water Tank capacity calibration: fill the Water Tank in the test box with water, and record the water capacity. Then set the test box to a certain humidity, 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 Test Chamber at that humidity. If the amount of water used is inconsistent with the capacity in the specification, a Water Tank capacity calibration adjustment is required.
NBCHAO reminds you: 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 performed by experienced technicians while following the equipment's operating manual.
Solutions to common problems
Also, here are some things that might help with common issues:
Inaccurate temperature or humidity readings: Check that the sensor is damaged or needs to be replaced, check that the sensor is positioned properly, and make sure the sensor is at the same temperature or humidity as the chamber.
Unstable temperature or humidity: Check whether the equipment is disturbed by the external environment, and ensure that there is no excessive humidity inside the chamber.
Debris or samples, make sure the test box is well sealed. 3. Uneven heating or cooling of the equipment: Check whether the heating or cooling elements are uniform, check whether the equipment needs to be cleaned or replaced, ensure that there are no excessive debris or samples inside the Test Chamber, and ensure that the Test Chamber is well sealed.
The equipment leaks water or the capacity of the Water Tank is insufficient: check whether the seal of the test box is good, check whether the Water Tank needs to be cleaned or replaced, ensure that there are no too many sundries or samples inside the test box, and replenish the water in the Water Tank in time.
Finally, in order to maintain the performance and reliability of the laboratory chamber, regular maintenance and maintenance are required. It is recommended to clean the interior of the test box regularly, and check the performance and condition of heating, cooling, control, sensors and other equipment, and replace or repair problematic parts in time. At the same time, it is recommended to carry out maintenance in accordance with the equipment operation manual and the maintenance instructions provided by the manufacturer to ensure the long-term stable operation of the test box.
