About the low temperature constant temperature and humidity test chamber measurement calibration appropriate way

Regarding the measurement and verification method of the environmental test equipment of the low temperature constant temperature and humidity test box, we should first grasp the characteristics and main uses
of the low temperature and constant temperature and humidity test chamber.

Low temperature constant temperature and humidity test chamber is the key machine and equipment for temperature and humidity detection, according to the scientific research operation of the machine and equipment, the other half of the detection of temperature and humidity detection, popularly speaking, that is to say, in the special temperature and humidity natural environment to be tested
.

The use of low temperature and constant temperature and humidity test chamber can reasonably test product quality and safety factor
.

The following is a scientific research discussion
on multiple measurement and verification problems of low temperature and constant temperature and humidity test chamber environmental test equipment.

New items, methods, measurements and calculations of low temperature and constant temperature and humidity test chamber measurements1, basic concepts: (1) Undulations: The main
parameters of the indoor space positioning point in the work of the environmental test equipment change with time under stable conditions.

(2) Precision: Under stable conditions, the difference
between the test cases (temperature and humidity) of the indoor space in the working room at a certain time under stable conditions.

(3) Deviation: Under the stable condition of machinery and equipment, the evaluation value measured by each control point of the indoor space in the work and the left and right deviations
of the evaluation low value and the tolerance value.

2, measurement verification characteristics: temperature and humidity deviation, temperature and humidity fluctuations, temperature and humidity uniformity 3, measurement verification method :(1) measurement verification is carried out
under the full load standard.

If it contains a load, the load status
should be indicated in the qualification certificate.

(2) Measurement and verification of turbid environment humidity points should usually be selected for the limitations, low limits and positioning points of the application of machinery and equipment, and can also be selected according to the customer's actual common temperature and humidity points (3) the parts of the measurement verification point: when the volume of machinery and equipment is lower than 2m3, the temperature point is 9, the ambient humidity point 3 machine and equipment volume exceeds 2m3, the temperature point is 15, and the temperature point is 4 according to the technical analysis of about the right, which we can see, Distinguishing a low-temperature constant temperature and humidity test chamber is a characteristic enough to meet the standard, the characteristics are not stable, if you refer to a good number of performance parameters around it
.

In addition, as a technical practical operation, grasping the technical basic common sense of the left and right is not only beneficial to the actual operation of the low-temperature constant temperature and humidity test chamber for proper scientific research, but also conducive to scientific research and maintenance of the machine and equipment
