Key technical indicators
1. Studio size: 225L (0.5 * 0.6 * 0.75 m);
2. The range of temperature: room temperature to 300 ℃
3. The temperature uniformity: + / - 1 ℃ or less;
4. The temperature fluctuation degree, plus or minus 0.5 ℃ or less;
Air conditioning system
1. Air conditioning method: forced circulation ventilation and balance adjustment method. The method not only refers to the refrigeration system under the condition of continuous work, of the temperature control system according to the set point automatically by the PID operation output result to control the output of the heater, eventually reach a dynamic balance;
2. Air circulation device: built-in air-conditioner, circulating air duct and long axial flow ventilator. By improving the air flow, the air flow, heating and cooling capacity are improved, and the temperature uniformity of the test box is greatly improved.
Enclosure structure
1. Outer wall material: high quality carbon steel plate (1.5mm), surface electrostatic spraying powder treatment;
2. Inner wall material of the box: SUS304 imported a first-class brushed stainless steel plate (1mm);
3. The internal welding of the box has high strength reinforcement;
4. Insulation: can be used to produce rigid polyurethane foam;
Measurement and control system
1. Temperature measurement: high precision (A) thermocouple;
2. Control device: the main controller of the test box adopts the American honeywell IPC2000 high precision double-loop programmable temperature controller;
3. The instrument has the PID parameter self-tuning function;
4. Indicate accuracy: 0.1 ℃;
5. Equipment has independent working time accumulative timer;
Safety protection measures
1. Safe and reliable grounding protection device;
2. Heater short circuit;
3. Fan overload;
Equipment conditions
1. Power source: 380V plus or minus 10% V, 50Hz, three-phase five-wire system;
2. The environment temperature: 5 ~ 30 ℃;
3. Ambient humidity: less than 85% R.H;
A satisfactory test method
The equipment meets gb2423.1-89, gb2423.2-89 test B: high temperature test method, GB/t2423.3-93 test Ca: constant humidity and heat test method, gb10592-89 high cryogenic tank technical conditions and gb10586-93 humidity and heat test box technical conditions, etc.
