Thermostatic test chamber TH series

climatichumiditytemperature

Overview
This TH series temperature and humidity test chamber features an inner operation door with a viewing/operation hole that enables inspection and limited manipulation of the test item without opening the main chamber door. The units deliver repeatable climatic conditions for industrial qualification and R&D across aerospace, automotive, electronics, materials and test laboratories. Multiple pre-engineered sizes and configurable options are available for different temperature/humidity ranges and ramp rates.

Key product features

• Inner transparent operation door with inspection/operation hole to observe or operate samples without disturbing chamber environment
• Energy-saving refrigeration design; option for electronic expansion valve
• PID control with touchscreen interface for precise setpoint management
• Wide temperature range options (low down to -70℃; high up to 150/180/200℃) and multiple humidity control ranges (5–98% R.H. options)
• Corrosion-resistant SUS 304 stainless steel interior for durability and easy cleaning
• Comprehensive protections: over-temperature, over-humidity, compressor overload, water-shortage warning and fault alarms

Applications

• Aerospace & Defense — environmental screening and qualification of avionics, sensors and components
• Automotive & EV — reliability and battery/environmental safety testing for ECUs, motors and cells
