Calibration Items including temperature point, wind speed, mesh sieve size, dust concentration.

 

Measurement method
No load: The measurement is carried out under no-load conditions. If there is a load, the load should be stated in the certificate.
Choose measure points: Measuring temperature should generally select the upper limit, lower limit and center point of the test chamber's use range, and the actual commonly used temperature points can also be selected according to user needs;
Location of measuring points: When the volume of the test chamber is less than 2m3, there are 9 temperature points; The test chamber volume is greater than 2m3, 15 temperature points. Use an anemometer to detect the wind speed inside the chamber.

 

The important notice after testing
1. Do not open the door of test chamber during the test;
2. If you hear any abnormal noise from the test chamber during operation, please stop the inspection and restart the machine after the fault is detected and resolved.
