1.2 studio materials: mirror stainless steel inner liner, movable stainless steel electropolishing shelf, tempered glass window,

1.3 Internal structure: Reasonable duct structure, air circulation design, fan forced circulation, to achieve all-round three-dimensional heating effect, to ensure that the working room has a good temperature uniformity, unique geometric cavity clean design.

1.4 thermal insulation material: high density glass fiber cotton, in front and rear sides of the box, the upper and lower layers are filled with heat insulation.

1.5 Sealing mode: High temperature resistant silicone rubber sealing strip is used in the door and studio to ensure the sealing of the studio. The inner plate of the door is made of stainless steel. A double-layer tempered glass observation window is arranged at the position of the box door, which is transparent and insulated to observe the change of the sample in the box. The back of the box body is provided with an air intake hole and a safety air vent, and the size of the air vent can be adjusted by a panel knob.

1.6 temperature measuring port: PT100 sensor enters from the rear of the box.

1.7 terminal:: the heating element is located at the bottom of the box.

1.8 controller: located on the left side of the box, with built-in control system.

1.9 heating element: stainless steel heater

2, temperature control system and characteristics

Personalized program design, LTDE programmable system, can be preset 30 segments of programmable, to achieve the pre-appointed temperature when running or step-by-step programming operation.

2.1PT100 high-responsiveness thermal sensor and environment scanning microprocessor chip constitute a high-precision, high-intelligence temperature control characteristics.

Built-in temperature corrector can adjust the small error of temperature. When the working temperature deviates from the set temperature, it can alarm automatically. It has automatic power-off protection for heater out of control.

2.2 has power-off recovery function, when the external power supply is restored to supply, the equipment can automatically follow the original set program for fast constant temperature. With parameter memory function, it can avoid tedious settings, automatic stop, timing operation, caller recovery, parameter memory, parameter password protection, temperature display correction.

Set the timing function, the period from 1 minute to 9999 minutes * 30 arbitrary set working time, the end of the timing will close the setting display window.

2.3 Setting parameters and actual parameters can be clearly displayed. LED clearly shows the setting temperature, measured temperature, timing time, the parameters are visible, with modular design of the upper limit of temperature tracking function, when the measured temperature deviates from the allowable range, the instrument sound (light) alarm and automatically cut off heating.

3. Wind circulation system

3.1 the circulating fan is located in the middle of the stainless steel heater in the back of the box.

3.2 Adopt long axis fan motor and multi-silk aluminum alloy blade to achieve horizontal convection-diffusion arc circulation of air in the box, so that the temperature in the box is uniform and stable all the time.

4. Heating system

4.1 stainless steel heater, located in the back of the box, is controlled by the PT100 sensor response system.

4.2 heating power output of heater is automatically controlled by microcomputer in automatic meter.
