Constant temperature and humidity testing machine specialized in manufacturing

1 Introduction: Walk-in constant temperature and humidity chamber suitable for aerospace products, information electronic instrumentation, materials, electrical and electronic products, a variety of electronic vitality at high temperature or humid environment, testing of its performance indicators. 2 Standard: This product complies with GB10592-89, GB10586-89, GB2423-1, GB / T2423.1-2001, GB / T2423.2-2001, GB2423.3-93 other national standards. 3 box structure: Walk-in constant temperature and humidity chamber chamber body base with 8 # channel welded into net framework, in order to be able to withstand the conditions in the horizontal body weight room and the staff of the specimen without generating chamber bottom surface irregularities uneven and cracking. Endurance 200kg / per square meter, the chamber body (test chamber body (housing)) is divided into six rooms and one pair of decent open the door to the chamber body, the size of 1800 × 2000 mm, chamber materials for high quality stainless steel liner (to prevent rust in the humidity of the inner wall of a long running state), outside the gall of quality steel (domestic brands), thermal insulation for polyurethane rigid foam medium heat, light resistance, fight, good insulation properties, Walk constant temperature and humidity chamber door material the same as the color steel plate, inside and outside the open door handle type, in order to test personnel from the closed interior freedom to open the door. 4 control system: temperature and humidity control instrument display using (Japan) all imported large screen (5.7-inch LED display), the screen is simple to operate, easy to edit programs, no key input, direct touch screen option. Accuracy: 0.1 ℃ (display range) Resolution: ± 0.1 ℃; temperature sensor: PT100 platinum resistance thermometer body; control: heat balance humidity thermostat mode; all appliances are used (Schneider) temperature and humidity control products using P .. I D + SSR system with coordinated control channel program with 10 groups, each group of 100 segments, each step can be recycled capacity of 999, each time setting a maximum of 99 hours, 59 minutes, 5 refrigeration system: compressor: Full German imports of semi-closed Copeland Refrigeration: cascade refrigeration, R22 single-stage refrigeration condensing mode: Wind cooling 6 Technical Specifications: Temperature range: -20 ℃ ~ + 100 ℃ (+ 150 ℃) Humidity range: 30 to 98% RH Temperature fluctuation: ≤ ± 0.5 ℃ temperature uniformity: ≤2 ℃ type and size (D * W * H mm): Model Studio Size Dimensions DEHP-4 4000 * 2500 * 2300 5100 * 2700 * 2550 / BJYSL- DHS-100
