What are the key parameters to pay attention to when choosing a high and low temperature test chamber?

 high and low temperature test chamber For such an important equipment, what key parameters should we pay attention to when purchasing?

  1. Impact temperature high and low temperature test chamber. The impact temperature refers to the maximum range of temperature that the test area can actually run. Note that it is not the limit temperature of the preheating and precooling rooms.

  2. Test load. This parameter directly affects how many test items can be placed. Generally speaking, the larger the weight, the better.

  3. Return time. It refers to the time it takes for the test product to switch from one temperature point to another temperature point. Our common standard convention is ≤5min. The shorter this time, the better.

4. Defrost time. high and low temperature test chamber The longer the defrost interval, the better. The quotation of the high and low temperature test chamber is now written that the manufacturer can defrost once 1000 cycles, which is very ideal. The shorter the defrost interval, the worse the air tightness of the equipment!

5. Sensor placement location. The specification requires that the sensor must be placed inside the test area. Some manufacturers place the sensor inside the air duct. Although it is only 10cm away from the test area, the energy difference is quite large. And it cannot truly reflect the temperature change on the surface of the test product.
