Two-box impact test chamber

-40℃~0℃ & 60℃~150℃

Heating rate of preheating zone(No load) 5 ℃/min (customizable for 10-25 ℃)
Cooling rate of pre cooling zone (No load) 2 ℃/min (customizable for 5-25 ℃)
Pre cooling area Pre cooling range-10℃~-55℃
Preheating area preheating range+60℃~+180℃
Temperature fluctuation≤1℃

The test basket of the double-chamber cooling and heating shock test chamber is mobile when conducting high and low temperature shock tests. The high and low temperature shock conversion is mainly completed by moving the test basket up and down in the high temperature zone and the low temperature zone. The impact recovery time of the double-chamber type is shorter than that of the three-chamber type.
