From 22L Benchtop to 8,000L Walk-In — Complete IEC 60068, MIL-STD-810 & ISO 16750 Coverage

Temperature & Humidity Test Chambers are precision climatic instruments that recreate, accelerate, and amplify the temperature and humidity conditions products encounter in real-world service — compressing years of field exposure into days or weeks of controlled laboratory testing. Every electronic device, automotive component, pharmaceutical product, aerospace part, packaging material, building product, and consumer item must perform reliably across a range of climatic conditions. By holding samples at precisely controlled temperatures and humidities (or cycling them rapidly through extremes), a modern test chamber reveals how a product will perform under desert heat, arctic cold, tropical humidity, freeze-thaw cycles, and the rapid thermal transitions that distinguish robust products from premature failures.

Qualitest offers one of the most comprehensive Temperature & Humidity Test Chamber portfolios available worldwide — covering the full spectrum from 22-liter benchtop chambers for compact R&D laboratories through 8,000-liter floor-standing landing-type chambers for full-system testing, plus walk-in chambers in six standard sizes (and customizable) for automotive battery packs, aerospace components, and large product assemblies. 

The portfolio's temperature capability ranges from −85 °C ultra-low-temperature cryogenic testing through +180 °C elevated-temperature qualification — supporting every climatic test method specified in IEC 60068, MIL-STD-810, ISO 16750, ICH Q1A, ASTM D2247, and dozens of other international standards.

The Qualitest portfolio includes five distinct platforms engineered for specific applications: the Quali22L™ Benchtop Environmental Chamber for compact electronics-QC testing with IEC 60068, ISO 16750, MIL-STD-810, JIS Z 0202, ANSI/TIA/EIA 455-162, ASTM D2247, and BS EN 61300-2-48 compliance; the QWIC-Series Walk-In Test Chambers with energy-saving VRF control and IEC 60068-3-5/3-6 performance values for full-product reliability testing; the Ultra Low Temperature Test Chamber with US-made R508 refrigerant and automatic refrigeration switching for cryogenic-zone applications; the Large-Capacity Landing-Type Chambers from 1,000L to 8,000L for relatively large products and full-system assemblies; and the flagship Platinum-Series energy-saving chambers covering −85 °C to +180 °C with world-class engineering at cost-effective prices.

Why Choose Qualitest for Your Temperature & Humidity Testing Needs

Qualitest is a globally recognized supplier of advanced climatic and environmental-testing instruments, serving customers worldwide with one of the most comprehensive Temperature & Humidity Test Chamber portfolios available — engineered to meet the full range of IEC, MIL-STD, ISO, ICH, and ASTM climatic-testing standards that modern industries demand.

Five-Platform Portfolio — One Trusted Source

From the compact 22L Quali22L™ Benchtop, through the QWIC-Series Walk-In Test Chambers, the Ultra Low Temperature Test Chamber for cryogenic applications, the Large-Capacity Landing-Type Chambers up to 8,000L, to the flagship Platinum-Series energy-saving chambers — Qualitest offers a coordinated portfolio matching every test volume, temperature range, and application demand.

Full Temperature Range: −85 °C to +180 °C

Qualitest temperature & humidity chambers span the complete operational spectrum from cryogenic Ultra Low Temperature Chambers reaching −85 °C with US-made R508 refrigerant and automatic refrigeration switching, through standard ambient/elevated chambers, to high-temperature platforms reaching +180 °C — covering every IEC 60068, MIL-STD-810, ISO 16750, and ICH Q1A test condition required for global product qualification.

Capacity From 22L to 8,000L

Whether you need a compact 22-liter benchtop chamber for individual electronic components, a six-standard-size walk-in chamber for automotive battery packs, or an 8,000-liter landing-type chamber for full-vehicle subsystems and large aerospace assemblies, Qualitest delivers the precise capacity match for your test program — eliminating wasted energy on oversized chambers and undersized work-volume frustrations.

Energy-Saving Platinum-Series & VRF Control

The flagship Platinum-Series chambers are designed with energy efficiency as a core engineering principle — delivering world-class quality and performance at substantially lower operating costs than legacy chamber designs. The QWIC-Series walk-in chambers add VRF (Variable Refrigerant Flow) control for the most efficient large-volume climate management available, with 4″ (100 mm) polyurethane foam panel insulation minimizing heat loss across long-duration tests.

Comprehensive International Standards Compliance

Every Qualitest chamber is engineered for full compliance with the world's leading climatic-test standards — IEC 60068 (full series including 60068-2-1, 60068-3-5, 60068-3-6), MIL-STD-810, ISO 16750, ICH Q1A, ASTM D2247, JIS Z 0202, ANSI/TIA/EIA 455-162, BS EN 61300-2-48, and many more — ensuring every test result is universally accepted, audit-ready, and defensible in customer certifications and regulatory submissions.

Built for Long Service Life

Stainless-steel interiors (Ultra Low Temperature Chamber), prefabricated panel systems with interlocking tight seals (QWIC walk-in), automatic refrigeration switching for efficient operation, durable industrial-grade construction, serviceable design, and proven refrigeration components combine to deliver year-after-year reliability — minimizing downtime, reducing total cost of ownership, and protecting your laboratory investment over an extended service life.

Cost-Effective Value & Global Support

Qualitest delivers premium temperature and humidity test chamber performance at a transparent, competitive price point — backed by global service, training, IQ/OQ/PQ qualification support, calibration services, and stocked spare parts worldwide. With worldwide presence, expert installation, operator training, and ongoing service are always within reach.

Simulate the World. Qualify with Confidence.

Every product in service will eventually face the worst weather, the harshest temperatures, the most punishing humidity its operational environment can throw at it — and the manufacturers who reliably deliver durable, regulator-compliant products are the ones that simulate those conditions in the laboratory before customers ever do. A poorly qualified electronic module fails in summer heat; an under-tested pharmaceutical product loses potency on the shelf; a battery pack fails the thermal-cycling specification; an automotive component triggers a costly recall. The companies that consistently launch reliable, durable, customer-trusted products are the ones equipped with temperature and humidity chambers built for precision, repeatability, and full international-standards compliance — and the Qualitest portfolio gives you exactly that.

Whether you are qualifying automotive electronics for thermal-shock cycling, supporting pharmaceutical stability testing under ICH Q1A guidelines, running EV battery-pack walk-in chamber testing, qualifying aerospace components across MIL-STD-810 temperature profiles, or running fundamental materials-science research, Qualitest has the temperature and humidity test chamber engineered to meet your exact needs. From the compact Quali22L™ Benchtop and the QWIC-Series Walk-In platforms, through the Ultra Low Temperature Chamber and the Large-Capacity Landing-Type Chambers, to the flagship energy-saving Platinum-Series, every Qualitest chamber delivers world-class climatic-testing performance backed by industry-leading service and support.
