Input digital correction system, built-in thermocouple and thermal resistance nonlinear correction form, accurate and stable measurement. With bit adjustment and AI artificial intelligence adjustment function 0.2 level accuracy, multiple alarm modes. Heating, cooling, humidifying, dehumidifying independent, unique BTHC balance temperature and humidity adjustment. The refrigeration system adopts fully closed inlet compressor unit, mechanical single stage refrigeration or overlay low temperature loop system, automatic control and safety protection coordination system. Stainless steel fin heating tube is used for heating. Product description: High and low temperature constant temperature and humidity box FR-1208 small constant temperature and humidity test box has the advantages of small shell case and large use space. The box body is machined with NC machine tool, the shape is beautiful and generous, the new and no reaction handle is adopted, and the operation is simple. Main functions: The equipment is mainly for the electrical, electronic products, and its original devices, and other materials in the high temperature, low temperature environment, storage, transportation, and use of the adaptability test. The test equipment is mainly used for the product in accordance with national standards or user requirements, at low temperature, high temperature, conditions, the physics of the product and other related special. Environmental simulation test, after testing, by testing, to determine the performance of the product, whether it can still meet the requirements for product design, improvement, identification and factory inspection. Main features: 1, the refrigerator uses the French original "Taikang" completely closed compressor. 2. The refrigeration system is designed by unit or binary low temperature loop system. 3. Multi-wing fan is used for strong air supply cycle to avoid any dead angle, and the temperature distribution in the test area is uniform. 4. The design of return air, wind pressure and wind speed are in accordance with the test standard, and the time of temperature stabilization can be faster at the moment of opening the door. 5, heating, cooling, complete independence of the system can improve efficiency, reduce test costs, increase life, reduce failure rate. 6, the temperature control adopts the all-import touch-key instrument, the operation setting is simple. 7. After input of data and test conditions, the controller has the function of locking, avoiding human touch and changing the temperature value. 8. With the function of P.I.D automatic calculation, the temperature change condition can be corrected immediately, and the temperature control can be more accurate and stable. Criteria met: 1.
