Box structure
  High and low temperature box using CNC machining, nice shape, and no reaction handle, easy to operate.
Imports of high grade stainless steel inner tank (SUS304) drawing board, box outside the gall A3 steel spray, increasing the appearance of texture and cleanliness.
Large observation window with bright lights to keep the box, and the use of heating element embedded glass, clear observation box at any condition.
The left side of the box with a 50mm diameter test holes for external test power line or signal line.
Control Systems
  High and low temperature import digital touch buttons, PID microcomputer programmable temperature controller SSR. Input data and test conditions, the controller has a locking function to avoid human touch and change the temperature. (Japanese chemical RKC Instrument)
With PID automatic calculation function can be immediately corrected temperature conditions, the temperature control is more precise and stable.
Optional printer.
Circulatory system
  High and low temperature chillers using original French "Taikang" closed compressor.
Refrigeration system using cryogenic unit or binary type loop system design.
Multi-wing powerful air circulation blower, to avoid any dead ends, make uniform temperature distribution within the test area.
Air duct return air circulation design of wind, air pressure, wind speed meet testing standards, and can open the door fast instantaneous temperature stabilization time.
High and low temperature heating and cooling system is completely independent to improve efficiency, reduce test costs, increase life and reduce the failure rate.
Standards compliant
