Climate chamber TH series

thermostatictemperaturehumidity

Overview
The desktop stability test chamber provides controlled temperature and humidity conditions for performance evaluation of aerospace, defense, marine, automotive, electronics, instrumentation, materials and battery systems. Pre-engineered and custom sizes are available across the TH series with configurable temperature ramp rates, humidity ranges and a variety of standard and optional features for steady-state, thermal cycling and rapid-change testing.

Applications

• Aerospace & defense: environmental stress screening for avionics, sensors and components under extreme temperature and humidity.
• Automotive & EV: reliability tests for ECUs, motors and automotive electronics; battery testing with explosion-proof options.
• Electronics & semiconductors: stability and humidity testing for PCBs, ICs, connectors and consumer devices before mass production.
• LED & lighting: thermal performance and humidity resistance validation for modules, drivers and luminaires.
• Packaging & transport: damp heat and temperature cycling for packaging materials and products exposed to long-distance shipping.
• Photovoltaics & new energy: damp heat and cycling tests for solar cells, modules and energy storage components.
• Materials research: accelerated aging and environmental stability evaluation for polymers, composites, coatings and metals.
• Universities & testing labs: standard-compliant conditions for research, certification and R&D testing.
