Technical difference between high and low temperature impact test box and high and low temperature test box

The reason why the high and low temperature impact test box is not the high and low temperature test box

Technical difference between high and low temperature impact test box and high and low temperature test box

The difference between the high and low temperature impact test box and the high and low temperature test box is the temperature rise and fall rate.

The maximum temperature rise and fall rate of the high and low temperature impact test chamber is generally greater than the range specified by the national standard. The common temperature rise and fall rate is 6 degrees Celsius / minute to 15 degrees Celsius / minute, but its rate can be set arbitrarily through the instrument control like an ordinary test chamber Set its rate.

The temperature rise and fall rate of the high and low temperature test chamber is much slower,

Heating time of high and low temperature test chamber

-70 ℃ ~ 100 ℃ is less than 55 minutes; -40 ℃ ~ 100 ℃ is less than 45 minutes;

-20 ℃ ~ 100 ℃ is less than 35 minutes; 0 ℃ ~ 100 ℃ is less than 30 minutes;

Cooling time of high and low temperature test chamber

+ 20 ~ -70 ℃ less than 80 minutes, + 20 ~ -40 ℃ less than 55 minutes,

+ 20 ~ -20 ℃ is less than 35 minutes, + 20 ~ 0 ℃ is less than 20 minutes,

Through the above technical analysis, we can conclude that the temperature shock test chamber and the high and low temperature test chamber have different functions due to the different temperature rise and fall rates. In the process of purchasing, customers need to understand according to the actual requirements of their own tests to achieve a reasonable order.
