Low pressure test chamber

Low pressure test chamber

Low pressure test chamber JOEO  Electrical,electronic,military industry and household products.According to GB,GJB and IEC standard,to do high low temperature,humidity thermal,low pressure and other environmental and reliability test.

JOEO altitude chambers,altitude test chamber is composed of test room formed by pressure-containing box shell and insulation structure, refrigeration system, add wet system,vacuum system and electric control system and other components.Low pressure test chamber JOEO is precision instruments support great extent electronics parts quality test than standard test chambers,for example - Military products.
Low pressure chamber are meet international standards DO160, ASTM, MIL-STD-781, -810 Altitude up-to 150,000 feet
Temperature range -70°C to +180°C, Humidity range 20 to 95%.

Description

1. Feature

Altitude Temperature Humidity Chamber Testing of avionics or other aerospace equipment to simulate actual conditions it might experience.
Simulation of high-altitude conditions like might be found in mountainous regions.

2. Structure

JOEO Low pressure test chamber have 13 process and 5 times quality control to ensure the accurate control of all details for altitude chambers,altitude test chamber,altitude testing chamber,temperature altitude chamber,high altitude test chamber,altitude test chamber manufacturers, composed pressure-containing box shell and insulation structure, refrigeration system, add wet system,vacuum system and electric control system and other components.
