Speciality

The testing chamber series is provided with a wider scope of temperature control and all performance indexes thereof reach technical condition of High & Low Temperature Testing Chamber National Standard GB/T10592. Low & high temperature experiments are applicable to the products as per GB/T2423. 1&2 Environmental Experiment of Electrician’s Electronic Product Experiment A: Method of Low Temperature Test, Experiment B: Method of High Temperature Test.
Temperature rise & fall properties:  
WGD42A
Performance & specialty:
 With adoption of imported parts as main parts, such product featuring excellent performance, beautiful appearance, and good reliability is an ideal choice for laboratory’s environmental equipment.
 A wider scope of temperature control is provided to meet customer’s various demands; digitally-displayed temperature is readable, visual, accurate and convenient;
 An Unique manner of equilibrium temperature regulation provided with stable and equilibrium heating capability is adopted for the implementation of high precise and stable temperature control;
 Turn-on function at high temperature is provided i.e. cooling machine can be started for the convenience of successive back-and-forth experiment implementations between high and low temperatures when temperature inside chamber rises to 130℃;
 Regulation of value of error can meet your experimental condition of better accuracy; the function of automatic selection of operating refrigeration circuit with set value of temperature is provided and easily operated;
 Test sample can be observed for experimental status at any time through large-area observation window incorporated with door of chamber; method of air cool is adopted for condensation in the refrigerating system.
