Instrument High and low temperature test chamber has the ability to accurately simulate complex natural environments such as high temperature, low temperature, and hot and cold climates, and is used to test and determine the environmental temperature changes of industrial materials or finished products and other semi-products for testing at constant temperature The final parameters and performance It is the heat resistance, cold resistance and dry resistance of the national defense industry, automation cAerospace industry components, marine parts, auto parts, electronic and electrical components, plastics, chemical industry, food industry, pharmaceutical industry and related products Ideal equipment for testing.
The range of degrees can be selected from the following:
1, high and low temperature range : A: 0℃, B: -20℃, C: -40℃, D: -60℃, F: -70℃～+150℃2, Temperature fluctuation: ±0.5℃
3, Temperature uniformity: ≤2℃
4, Heating and cooling rate: 0.7~1℃/min
5, volume and corresponding width, height and Tiefe selectable: 80L: width 40x height 50x depth 40cm; 150L: 150L: width 50x height 60x depth 50cm; 225L: width 50x height 75x depth 60cm; 408L: width 60x height 85x depth 80cm; 800L: width 100x height 100x depth 80cm ; 1000L: width 100 x height 100 x depth 100 cm.
Instrument high and low temperature test boxStructural features:
The test box is mainly composed of a box heating system , a cooling system, an air circulation system and a control system.
The outer casing of the test box is made of high-quality SUS304 stainless steel oil-hair plate or cold-rolled Baosteel steel plate electrostatically sprayed. and the inner tank is made of 100% high-quality SUS304 stainless steel sheet. Large-area observation window, equipped with observation lights to let users see the test situation of the sample clearlycan see.
The refrigeration The system uses a fully enclosed imported compressor unit, mechanical single-stage refrigeration or cascade low-temperature circulatory system, fully automatic control and safety protection coordination system.
Heating system made of panel-shaped Stainless steel nickel chrome electric heater (overshoot is small).
The overall appearance is beautiful and generous. The insulating layer is made of rigid polyurethane foam plus a small amount of ultra-fine glass wool, which has the characteristics of high strength and good heat retention.
The main temperature controller of the test box adopts the Japanese OYO9256P intelligent touch screen temperature and humidity controller, the operation method of humanized design, easy to learn and use, and the instrument operation of different functional degrees is compatible The input uses a digital correction system, a built in commonThermocouple and a non-linear thermal resistance correction form, the measurement is accurate and stable Precision, multiple alarm modes Cool down, rise. Temperature, independent and efficient BTHC balance temperature adjustment method.
