Temperature Humidity Test Chamber GAG-E201 / GAG-E202

Temperature humidity test chamber GAG-E201 (with humidity control) and GAG-E202 (temperature only) simulate combined climate conditions to verify how your product behaves before your customer ever sees it. Six standard working volumes from 100 L to 1000 L, three temperature range options down to −70°C, and humidity from 20% to 98%RH make the series a fit for electronics, automotive parts, rubber and plastics, chemicals, building materials and food products. Every chamber is built and tested in our own factory and can be customized in size, range and cooling configuration.

Key Advantages of the GAG-E Temperature Humidity Test Chamber

Stable, Accurate Climate Control

Temperature fluctuation is held at ±0.3°C, with deviation within ±1.0°C up to 100°C and ±1.5°C up to 150°C. Humidity is controlled from 20%RH to 98%RH (10%RH available as an option) with a uniformity better than ±3%RH and 0.1%RH resolution, so your test reports stay defensible in customer and third-party audits.

International Brand Core Components

The refrigeration section uses Tecumseh and Copeland compressors, and the control system is a color touchscreen programmable controller with fixed-point, programmable and curve modes. Test data can be exported through USB or network port for report filing. Components are chosen for availability: when a spare part is needed years from now, it can be sourced locally in most countries.

SUS 304 Stainless Working Space

The interior is full SUS 304 stainless steel with silicone door sealing and an observation window with interior lighting. The exterior shell is Fe360B steel with a high-temperature resistant coating. This combination resists corrosion in high-humidity testing and keeps the chamber presentable after years of daily cycles.

Factory-Direct Customization

Beyond the six standard volumes, the inner dimension, temperature range, cooling rate and humidity floor can all be customized. Cooling rates of ≥3°C/min or ≥5°C/min (down to −70°C models) are available for labs that run thermal cycling schedules instead of steady-state soaks. Tell us your test standard and sample size, and we configure the chamber around it.

Performance Parameters

Construction and Control System

Chamber Body

Inner chamber: SUS 304 stainless steel, argon-arc welded and pressure checked. Outer shell: Fe360B steel plate with high-temperature powder coating. Between them lies 100 mm of insulation that keeps the outer surface cool even at 150°C setpoints. The observation window uses multi-layer heated glass to stay frost-free during low-temperature runs, and a 50 mm cable port (diameter customizable) brings power and signal lines to your samples under test.

Touchscreen Programmable Controller

The color LCD controller supports fixed-value running, multi-segment programming (up to 120 segments, 999 cycles) and real-time curve display. Setpoints, alarms and test data can be downloaded via USB or RS-232/485 and exported as curves for quality records. Multi-point temperature monitoring channels are standard, so you can verify deviation with your own sensors, not only the controller's.

Refrigeration and Humidification

Tecumseh (France) and Copeland (USA) compressors form the cascade refrigeration stage on −40°C and −70°C models. The humidification system uses a stainless steam boiler with low-water protection and automatic water supply connection. All wiring follows CE practice, and every chamber runs a no-load temperature and humidity verification before packing.

Applications: What Can You Test in This Chamber?

• Electronics and electrical appliances. Damp heat and thermal cycling for PCBAs, modules and finished units, referenced to IEC 60068-2-78 (steady state damp heat), IEC 60068-2-30 (cyclic damp heat) and IEC 60068-2-2 (dry heat).

• Batteries. High-temperature storage and temperature cycling preparation for UN 38.3 (T2 to T3 conditioning) and cell-level climate checks before abuse testing.

• Automotive and motorcycle parts. Combined temperature and humidity endurance for sensors, connectors, dashboards and control units.

• Rubber, plastics and polymers. Heat aging and humidity-driven degradation studies, hardness and tensile retests after exposure.

• Chemicals and building materials. Stability and storage conditioning of adhesives, coatings, cement samples and composite panels.

• Food and packaging. Shelf-life conditioning and transit climate simulation for sealed packages and labels.

Which Model Should You Choose?

A practical rule: the sample plus fixtures should not exceed one fifth of the working volume, and airflow needs at least 100 mm clearance around every specimen. Bench-scale electronics fit the 100 L or 150 L. Complete assemblies and small appliances fit 252 L to 408 L. Battery modules, cartons and multi-tray loads need 800 L or 1000 L. If your schedule includes fast thermal cycling (for example −40°C to +85°C in under 90 minutes), specify the ≥3°C/min or ≥5°C/min cooling option; a standard 1°C/min machine will stretch each cycle into hours.
