Products fail in the field because they were never tested under the conditions they will actually face. The Temperature Humidity Chamber recreates those conditions in a controlled enclosure, cycling through temperature and humidity profiles that reveal weaknesses before a product reaches a customer. This Temperature Humidity Chamber is built for electronics manufacturers, automotive suppliers, aerospace laboratories, and material testing facilities that need programmable, repeatable environmental stress testing without settling for a chamber that drifts or underperforms.

Key Benefits: Programmable Environmental Stress Without Constant Supervision

Wide Temperature Range for Diverse Test Profiles

The Temperature Humidity Chamber offers temperature options from -20°C down to -60°C and up to +150°C. Whether you are testing electronics for tropical humidity, automotive components for winter cold starts, or aerospace avionics for rapid altitude shifts, the chamber reaches and holds the conditions your standard requires.

Programmable Control for Unattended Cycling

The touch screen controller stores up to 120 program groups with 100 sections each, and links programs together for complex multi-stage profiles. Each operation can cycle up to 9999 times. You set the profile once, and the chamber runs the full sequence without an operator adjusting setpoints between stages.

Tight Humidity Control Across the Full Range

Humidity is controlled from 20% to 98% RH with ±1% RH accuracy and ±2% RH uniformity. For THB (temperature-humidity-bias) testing of PCBs or stability testing of packaging materials, the chamber holds the moisture level your test protocol specifies rather than drifting toward ambient.

Multiple Chamber Volumes for Different Sample Loads

Six test space options run from 80L to 1000L. A small R&D lab can start with the 80L unit for component-level screening, while a production quality department can run full assemblies in the 1000L chamber. The control platform is consistent across sizes, so test profiles transfer between units.

Solving the Problems That Slow Reliability Testing Down

Struggling to run multi-stage temperature and humidity profiles without babysitting the chamber?
The programmable controller stores 120 program groups and links them in sequence. Each group can run 100 sections and cycle up to 9999 times. Set the profile, start the run, and the chamber executes without intervention.

Concerned about humidity drift during long THB tests?
Humidity control holds ±1% RH accuracy and ±2% RH uniformity across the 20% to 98% range. The chamber maintains the setpoint rather than letting ambient conditions pull the reading off target.

Tired of chambers that take too long to reach temperature?
The GT-C52 heats from room temperature to 150°C in approximately 45 minutes and cools to -20°C in the same timeframe. Test cycles complete faster, and the chamber spends less time in transition.

Need a chamber size that matches your sample without overbuying?
Six volumes from 80L to 1000L let you match the chamber to the load. You do not need to fill a 1000L chamber with small components, and you do not need to split large assemblies across multiple runs.
