The programmable constant temperature and humidity Test Chamber is a high-precision constant temperature and humidity test equipment, which is often used in laboratories and production lines in the fields of materials, electronics, chemicals, food, and pharmaceuticals. Here are some common problems you may encounter and how to calibrate them:
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.
An error occurred in program operation.
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. Calibration can be done by program setting or by adjusting the sensor circuit.
Humidity Calibration: Use a humidity calibrator to place 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 Test Chamber. If there is a difference, a calibration adjustment is required. Calibration can be done by program setting 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 whether the readings of each metering point are consistent. If there is a difference, a uniformity calibration adjustment is required. Calibration can be done by program setting or by adjusting the sensor position.
Equipment Water Tank capacity calibration: fill the Water Tank in the Test Chamber with water, and record the water capacity. Then set the Test Chamber 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 obtain 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. Calibration can be done through program settings or by adjusting the volume of the Water Tank.
NBCHAO reminds you: the programmable constant temperature and humidity Test Chamber needs to be calibrated and maintained regularly, and the program needs to be updated and maintained at the same time. 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. In addition, it is recommended that according to the operation manual of the equipment and
Carry out maintenance according to the maintenance guidance provided by the manufacturer, regularly clean the inside of the equipment, 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 cut off the power of the equipment before performing maintenance, and wait for the equipment to cool down before operating to ensure safety.
Precautions for use
In the process of using the programmable constant temperature and humidity Test Chamber, the following points need to be paid attention to:
Reasonably arrange the placement of samples to ensure that the samples can be subjected to uniform temperature and humidity distribution.
Do not accumulate too much sundries or samples inside the Test Chamber to avoid affecting the operation of the equipment and the accuracy of the data.
According to actual needs, reasonably select the temperature and humidity range and accuracy of the Test Chamber to avoid inaccurate test data due to mismatching equipment parameters.
Before testing, perform preheating or precooling to ensure that the equipment can reach the required temperature and humidity conditions.
During the use of the equipment, the temperature and humidity changes and test data are recorded in time, and analyzed and processed as needed.
In short, 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, but at the same time, attention should be paid to the use and maintenance of the equipment to ensure the stability of the equipment and the accuracy of the test data .
