To choose a step-in high-temperature aging room, you must first understand its most basic technical parameters, so that you can find a more suitable equipment.
The first thing we think about is the size. If the equipment purchase is small, the test product can not enter the cabinet or affect the product test results; the equipment purchase is large, increase the capital cost, and reduce the equipment utilization. Therefore, we must first consider the size of the equipment when purchasing equipment. In general, the standard size is: 450 × 450 × 500 / 500 × 600 × 750 / 700 × 800 × 900 / 800 × 1000 × 1000 / 1000 × 1000 × 1000 corresponding volume is: 108L / 225L / 504L / 800L/1000L
The second is the temperature range, high and low temperature range: A, -20 ° C ~ 150 ° C, B, -40 ° C ~ 150 ° C, C, -60 ° C ~ 150 ° C, D, -70 ° C ~ 150 ° C, E, - 80 ° C ~ 150 ° C, the lower the temperature, the higher the equipment, because the number of compressors used in different temperatures is completely different.
Other technical parameters of walk-in high and low temperature aging room:
Temperature uniformity: ≤ 2 ° C (at no load)
Temperature fluctuation: ±0.5 °C (at no load)
Cooling rate: 0.7~1.0°C/min
Heating rate: 1.0 to 3.0 ° C / min
Time setting range: 1~9999H
The equipment can also be referred to the standard: GB/T2423.1-2008 Test A Low Temperature Test Method, GB/T2423.2-2008 Test B High Temperature Test Method
I hope that the above can help users who are preparing to purchase walk-in high and low temperature aging rooms.
