Summary
Precision temperature and humidity test chambers designed for stable, wide-range environmental testing in industrial and laboratory settings. Applicable for performance testing across aerospace, marine, defence, automotive, information electronics, instruments and meters, materials and electronic engineering products. ASLI offers configurable sizes and options to meet specific test requirements.

Product description
This constant temperature and humidity test chamber is engineered to evaluate product performance under controlled climatic conditions. ASLI provides standard and custom sizes, a wide range of temperature ramp rates, humidity levels and numerous standard and optional features including temperature cycling, steady-state testing and rapid change capability. Optional items include access ports, explosion-proof construction, silent mode, additional shelving, battery safety options, dry air purge, water filtration/demineralization system and more.

Applications

• Aerospace & Defence: environmental stress screening for avionics, sensors and components under extreme temperature and humidity conditions.
• Automotive & EVs: reliability testing for ECUs, motors and electronic components under thermal cycles and humid heat.
• Electronics & Semiconductors: stability and humidity testing for PCBs, ICs and connectors.
• LED & Lighting: thermal performance and moisture resistance validation for LED modules and drivers.
• Packaging & Transport: humid heat and temperature cycle tests for packaging materials and products exposed to long-distance shipping.
• Photovoltaics & New Energy: thermal cycling for solar cells, modules and energy storage components.
• Materials Research: accelerated ageing and environmental stability evaluation for polymers, coatings and metals.
• Universities & Laboratories: controlled test conditions for research projects and certification.

Common test standards
IEC 60068-2-1 (Cold); IEC 60068-2-2 (Dry heat); IEC 60068-2-78 (Damp heat, steady state); IEC 60068-2-30 (Damp heat, cyclic); ISO 139; ASTM D1776; MIL-STD-810; GB/T 2423. Final compliance depends on chamber configuration and selected standard version.
