Difference: high and low temperature test chamber is mainly temperature change humidity constant environment, high and low temperature alternating test chamber is the temperature change and alternating hot and humid environment.
Similarity: can be applied to high temperature, low temperature, heat and humidity test test. Used for electronic and electrical components, automation parts, communication components, automotive parts, metals, chemical materials, plastics and other industries, the defense industry, aerospace, military industry, BGA, PCB base wrenches, electronic chips IC, semiconductor ceramic magnet, optical fiber, LED, crystal, inductors, PCB, batteries, computers, cell phones, and polymer materials of the physical changes in the livestock to test the material of the high and low temperatures of the repeated resistance to the tensile force And products in the thermal expansion and contraction of the output of chemical changes or physical damage, the Standard Group (Hong Kong) Limited? That it is necessary to comply with the standard:
"GB10592-89" high and low temperature chamber technical conditions;
"GB10586-93" hot and humid chamber technical conditions;
"GB2423.1-89 electrical and electronic products, the basic environmental test procedures": low-temperature test methods;
"GB2423.2-89 electrical and electronic products, the basic environmental test procedures": low-temperature test methods;
"GB2423.2-89 electrician GB/T2423.2-89 Basic Environmental Test Procedures for Electrical and Electronic Products: High Temperature Test Methods;
GB/T2423.4-93 Basic Environmental Test Procedures for Electrical and Electronic Products: Alternating Humidity and Heat Test Methods;
GB/T2423.3-93 Basic Environmental Test Procedures for Electrical and Electronic Products: Constant Humidity and Heat Test Methods.
Control system:
1. When there is a short circuit, leakage, studio over-temperature; compressor overpressure, overload, oil pressure, water and other abnormalities, the screen immediately and automatically display the cause of the failure and to provide the elimination of the method, and when found that the input voltage is unstable, with an emergency stop device.
2. Ln2 rapid cooling control system, simple operation mode, power on simple settings can run.
3. Fully automatic, high-precision system, any machine action, completely locked by the P.L.C processing.
4. With RS-232C communication interface device, can be connected to the computer control/edit/record and ten dynamic links to use convenient. When executing cold and heat shock conditions, you can choose the function of 2 Zone or 3 Zone.
