Three slot high and low temperature impact test chamberKey Features:

The inner box is made of SUS # 304 stainless steel plate, and the outer box is made of SEEC steel plate with electrostatic spraying or stainless steel drawing plate, which increases the appearance texture and cleanliness, and has a beautiful and elegant shape;

The insulation layer of the box adopts high-strength PU and insulation cotton to achieve excellent insulation effect;

The box is equipped with a test hole with a diameter of 50mm, which can be used for external testing power or signal lines. The aperture and number of holes can be customized according to customer requirements;

The bottom of the machine adopts high-quality fixed PU movable casters, which are easy to move;

It can independently set up three different conditions: high temperature, low temperature, and thermal shock, and has the function of a high and low temperature testing machine;

It can automatically preheat, pre cool and standby in the scheduled start-up time control, and can choose the starting position to start cycling or impacting from high or low temperature. It has the functions of setting the number of cycles and automatic defrosting;

Equipped with fully automatic and high-precision system circuits, any component action is locked and processed by P.L.C. The temperature control accuracy is high, and all are controlled by PID automatic calculation;

The air outlet and return air outlet are controlled by sensors, and the switching time of the wind direction gate mechanism is completed within 10 seconds. The recovery time of the cold and hot shock temperature is completed within 5 minutes;
