Regarding the measurement and verification method of the environmental test equipment of the high and low temperature test chamber, we should first grasp the characteristics and main uses
of the high and low temperature test chamber.
High and low temperature 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 test to carry out temperature and humidity detection, popularly speaking, that is to say, in the special temperature and humidity natural environment to be tested
.
The use of high and low temperature test chambers can reasonably test product quality and safety factor
.
The following is a scientific research discussion
on multiple measurement and verification problems of high and low temperature test chamber environmental test equipment.
New items, methods, measurements and calculations of the measurement verification of high and low temperature test chambers: (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 application of machinery and equipment restrictions, low limits and positioning points, but also according to the customer must select the actual common temperature and humidity points (3) measurement verification point parts: when the volume of machinery and equipment is less than 2m3, the temperature point is 9, the ambient humidity point 3 machine and equipment volume exceeds 2m3, the temperature point is 15, the temperature point is 4 According to the technical analysis, we can see that distinguishing a high and low temperature test box is a characteristic enough to reach the standard, The characteristics are not stable, if you refer to a number of performance parameters left and right
.
In addition, as a technical practical operation, grasping the technical basic common sense of the left and right is not only beneficial to the practical operation of the high and low temperature test chamber for proper scientific research, but also conducive to scientific research and maintenance of the machine and equipment
.
