Overview
This stainless-steel environmental test chamber (TH series, models TH-80 to TH-1000) provides controlled temperature and humidity conditions for repeatable environmental testing. It is suitable for industrial and laboratory use where precise thermal and humidity profiles are required for R&D, quality control and qualification testing.

Key Features

• PID controller with 7" touchscreen for programmable profiles and stable control
• Control accuracy: ±0.5℃; ±2.5% R.H.
• Analytic accuracy / distribution uniformity: 0.1℃; 0.1% R.H. / ±2.0℃; ±3.0% R.H.
• Energy-efficient refrigeration with electronic expansion valve and high-density insulation
• Inner chamber: SUS 304# stainless steel; outer cabinet: stainless steel or painted cold-rolled steel
• Humidity options selectable: 20–98%, 10–98% or 5–98% R.H.
• Comprehensive protections: over-temperature, over-humidity, compressor overload, water-shortage alarms
• Optional accessories: access ports, inner door with operation hole, recorder, water purifier, dehumidifier, explosion-proof and battery-safety configurations

Applications

• Aerospace & Defense — environmental stress screening for avionics, sensors and aerospace components
• Automotive & EV — reliability and battery testing (explosion-proof configurations available)
• Electronics & Semiconductors — humidity and thermal stability tests for PCBs, ICs and connectors
