Control System: Adopts black aluminum plate to connect temperature sensor and adopts black board temperature meter to control heating so as to ensure more stable temperature.
The radiometer probe is fixed so as to avoid the frequent installation and disassembly.
The radiation quantity adopts the special UV irradiatometer with high-precision display and measurement.
The radiation intensity is not more than 50W/m2.
The illumination and condensation can be controlled independently or alternating and circularly.
Box structure
Box with CNC machine tool processing molding, nice shape, two-way clamshell lid, easy to operate.
Box liner imported high-grade stainless steel plate, box outside the gallbladder with A3 steel spray, an increase of the appearance of texture and cleanliness.
Heating tank liner type heating, heating up fast, uniform temperature distribution.
Drainage system uses the eddy-type and U-type sedimentation device drainage, user-friendly cleaning
