ISO 139 and ASTM D1776 Temperature Humidity Test Chamber for Textile is also called environment testing machine, used to test various types of materials for their tolerances of heat, cold, dry, humidity. It is applied for quality inspection for all types of electronic products, electric appliance, and products from communication, instrument, automobile, plastic, metal, food, chemical, building materials, medical and aerospace industries.
The constant temperature and humidity test chamber is widely used in the following industries for reliability, stability, and environmental testing.
Environmental stress screening for avionics, sensors, and aerospace components under extreme temperature and humidity conditions.
Reliability testing for ECU, motors, and automotive electronics under thermal cycling and damp heat exposure. Battery testing requires explosion-proof configuration; contact us for details.
Stability and humidity testing for PCBs, ICs, connectors, and consumer electronics before mass production.
Thermal performance and humidity resistance validation for LED modules, drivers, and luminaires.
Damp heat and temperature cycling for packaging materials, containers, and products exposed to long-distance shipping.
Damp heat and temperature cycling for solar cells, modules, and energy storage components.
Accelerated aging and environmental stability evaluation for polymers, composites, coatings, and metals.
Standard-compliant test conditions for research projects, academic studies, and third-party certification labs.
Final compliance depends on chamber configuration, test setup, and the latest version of each standard.
PID control and a 7" touch screen help maintain ±0.5℃ and ±2.5% R.H. control accuracy, reducing invalid tests and retests.
Electronic expansion valve system and high-density insulation support lower power consumption and long-term operating cost.
SUS 304# stainless steel interior resists corrosion, simplifies cleaning, and extends service life.
Choose 20–98%, 10–98%, or 5–98% R.H. to match different material and product test requirements.
Over-temperature, over-humidity, compressor overload, and water-shortage protection help protect operators and samples.
Standard USB, remote data access, multilingual display, and alarm history make reporting, troubleshooting, and audits easier.
