Validate Product Reliability with
JCT Temperature and Humidity Chamber
A constant temperature and humidity chamber is a precision environmental testing chamber .It is engineered to simulate natural extremes of heat, cold, and damp-heat. It can help you to expose critical vulnerabilities—like moisture ingress, material swelling, and electrical short circuits—long before mass production.
Why Skipping Climatic Testing is a Costly Gamble?
Industrial and consumer products are shipped globally. If your products are not validated against extreme climates testing, you are facing into massive financial risks
Prevent Catastrophic Field Recalls
What it does:
Your Products shipped to tropical or freezing regions,will encounter environments that they were never tested for. Glues fail, screen edges peel, metals rapidly rust, and PCBs short-circuit, all the above will trigger a devastating brand crisis and massive warranty claims
The Benefit:
Our Environmental Test Chamber simulate these extreme environments in your lab, ensuring your product’s structural and electrical integrity before a single unit is shipped globally.
Cross Strict Supply Chain Thresholds
What it does:
You engineer a great product, but are locked out of lucrative Tier-1 automotive, aerospace, or military supply chains,just because you lack compliant environmental testing data.
The Benefit:
We can Provide traceable reliability testing reports based on IEC, ISO, or GB standards . Our temperature and humidity chamber can output exact, audit-ready thermal and humidity logs to secure your compliance.
Radically Compress R&D Cycles
What it does:
If Waiting for natural weathering ,it will take several years. Discovering a fatal material degradation flaw after 2 years of natural use ,that means your entire product generation is already compromised.
The Benefit:
By Utilizing extreme damp-heat environments (like the classic 85℃/85%RH test) in our Constant Temperature and Humidity Chamber to accelerate material aging, We will help you simulate years of natural environmental erosion in just a few weeks, exposing design flaws instantly.

Core Technology
The 4-System Dynamic Balance
Our Constant Temperature and Humidity Chamber maintain perfect environmental equilibrium through a dynamic interplay of 4 subsystems.Electric heating wires elevate temperatures,Imported mechanical compressors drive refrigerants to cool the zone.Steam generator injects precise water vapor for humidification, and the evaporator’s condensation effect will strip moisture from the air for dehumidification.A heavy-duty centrifugal fan forces this conditioned air into every corner of the workspace, completely eliminating dead zones.
Precision PID & PT100 Sensors
The core of our environmental test chambers lies in algorithmic control. High-precision PT100 platinum resistance sensors acutely capture the slightest thermal or moisture deviations. The smart PID controller instantly calculates and commands micro-adjustments across the heating and cooling systems, allowing the chamber to run continuously for months with ultra-low fluctuations (±0.5℃, ±2.0%RH).
Applications
semiconductor packaging
Semiconductor epoxy molding compounds (EMC) are highly hygroscopic. If a microchip absorbs too much atmospheric moisture before surface mount technology (SMT) assembly, the intense 260℃ heat of reflow soldering vaporizes the trapped water instantly. This extreme internal pressure causes the IC package to crack and shatter—known as the “Popcorning” effect. Our JCT constant temperature and humidity chambers allow you to execute strict pre-conditioning moisture soak tests (e.g., JEDEC standards), completely preventing catastrophic assembly-line failures
photovoltaic solar panels
Solar panels are expected to operate flawlessly for 25+ years outdoors, facing constant rain, humidity, and heat. The rigorous “Double 85” test (85℃ / 85% RH for 1000+ continuous hours) is mandatory for PV modules. It strictly verifies the moisture barrier capabilities of EVA encapsulant films and backsheets. By Using our JCT environmental test chambers ensures that damp-heat won’t cause severe delamination, busbar corrosion, or dangerous electrical leakage in real-world solar farms.
consumer electronics
High-density PCBs in smartphones and laptops are incredibly vulnerable to moisture. Prolonged exposure to high humidity triggers Conductive Anodic Filament (CAF) growth and ion migration between tight copper traces, leading to hidden micro-short circuits. Additionally, damp-heat causes smartphone screen adhesives to bubble or peel. Using our JCT environmental test chambers ensures consumer devices survive tropical climates without glitching or falling apart.
Automotive interior materials
A parked car in the summer sun acts like a greenhouse, trapping extreme heat and humidity inside the cabin. We can simulate these exact closed-cabin damp-heat environments to test automotive leather seats, dashboard plastics, and structural adhesives. By using our JCT constant temperature and humidity test chamber ,you can test whether interior materials will crack, become unpleasantly sticky to the touch, or release harmful VOC (Volatile Organic Compound) odors when baked at 85℃ and high humidity.
Lithium Batteries
Moisture is the ultimate enemy of lithium-ion batteries. If an EV battery pack’s sealant degrades and allows moisture to penetrate, the cells will suffer severe capacity degradation and internal short circuits, ultimately triggering catastrophic thermal runaway and vehicle fires.Our JCT temperature and humidity chamber performs strict moisture-proofing and seal integrity evaluations under alternating temp-humidity cycles, guaranteeing your battery packs remain 100% waterproof in all climates.
LED Outdoor Lighting
Heavy-duty streetlights and automotive headlights heat up during use and cool down rapidly in the rain, creating a vacuum that pulls external moisture into the housing. By using our JCT temperature and humidity chambers to testing the waterproof breathable valves ,it verifies that this external damp-heat and internal cold-hot cycling won’t cause condensation, fogging, or water pooling on the lenses, ensuring maximum visibility and preventing LED driver corrosion

FAQ
Q1: What exactly is a Constant Temperature and Humidity Chamber?
It is an environmental testing system that simulates specific extreme climatic conditions through dynamic heating, cooling, humidification, and dehumidification.
It provides an extremely stable and uniform artificial environment for the test specimens.
Its core function is to simulate long-term climatic stresses found in nature by maintaining (or alternating) specific temperature and humidity parameters over extended periods (such as the classic “double 85” test: 85°C, 85% RH).
.
Q2:What are the fundamental differences between it and high- and low-temperature test chambers and Rapid-Rate Thermal Cycle Chambers?
Constant temperature and humidity chamber can achive precise moisture control (active humidification and dehumidification). High/low temperature chambers only perform dry cold/dry heat tests
Constant temperature and humidity chamber focuses on steady-state long-term stability with gradual temperature transitions.
In contrast, rapid rate thermal cycle chambers or thermal shock chambers )inflict rapid thermal expansion stress using extreme ramp rates (e.g., 15°C/min to instantaneous transfer).
Q3: What types of reliability tests is this environmental test chamber used for?
High-Temperature High-Humidity Aging (85/85 Test): Evaluates the moisture vapor transmission resistance of encapsulation materials and solar modules.
Insulation Resistance Moisture Testing: Checks if printed circuit boards (PCBs) suffer from Conductive Anodic Filament (CAF) failure, ion migration, or short circuits in high-moisture environments.
Long-Term Stability Testing (ICH Guidelines): Monitors physical and chemical degradation (e.g., moisture absorption, emulsion separation) of pharmaceuticals and cosmetics over their designated shelf life.
Material Hydrolysis & Moisture Absorption: Validates the mechanical strength decay of plastics, coatings, and packaging materials after prolonged moisture exposure.
Q4: What is the famous "Double 85" test?
The Double 85 test requires the temperature and humidity chamber to run continuously at 85℃ and 85% RH ,for hundreds or thousands of hours (e.g., 1000 hours for solar panels). It is a brutal accelerated aging standard used globally to test material degradation
Q5: What is the lead time for a constant temperarute and humidity chamber?
Standard configurations of the JCT-CTH 112 (150L) and 122 (400L+) models typically ship within 15-20 business days. Custom sizing or specialized cooling upgrades will take approximately 3-4 weeks. Submit a request below for exact timing.
