When products are exposed to rapid climate shifts, humidity changes, or mechanical shocks, the only way to validate long-term durability is through precise simulation. Real-world testing is not always feasible, but a laboratory chamber that can reproduce extreme conditions with repeatable accuracy gives manufacturers the assurance they need before launching products.
LIB's Thermal Cycling and Vibration Chamber integrates temperature, humidity, and vibration testing into one solution. With programmable precision, international standards compliance, and built-in reliability features, it is engineered for industries where safety, performance, and certification depend on accurate environmental data-such as automotive, aerospace, electronics, defense, and renewable energy.
How Does a Thermal Cycling and Vibration Chamber Ensure Accurate and Realistic Temperature, Humidity, and Vibration Testing?
【Your Core Thermal Cycling & Vibration Essentials】
Standards Compliance
Meeting strict standards ensures that your results are valid worldwide:
IEC 60068: Environmental testing for electrical/electronic equipment.
ISO 16750: Road vehicles-environmental conditions and tests.
IEC 61730: Safety and weathering tests for photovoltaic modules.
ASTM D2247: Practice for testing coatings in controlled humidity.
IEC 60068-2-6 & 2-27: Sinusoidal vibration and mechanical shock testing.
Test Precision & Repeatability
LIB chambers achieve stable and traceable results with:
Wide Range: –70 ℃ to +150 ℃, programmable in 0.1 ℃ steps.
Low Deviation: ± 0.5 ℃ temperature fluctuation; ± 2.0 ℃ max deviation.
Humidity Accuracy: 20 %–98 % RH within ± 2.5 % RH.
Ramp Rates: Heating up to 3 ℃/min, cooling at 1 ℃/min.
Sensors: PT100 Class A sensors (± 0.001 ℃ precision) and chilled-mirror humidity sensors.
Vibration Load: 240 mm shaker platform, up to 500 kg, supporting vertical and horizontal modes.
These precise tolerances mean that whether you are performing Accelerated Life Testing (ALT) on circuit boards or validating safety electronics against thermal cycling stress, you can trust that data drift will not compromise results.
Operational Efficiency
7-inch Touchscreen Controller: Stores 120 programs × 100 steps each for complex multi-stage profiles.
Connectivity: USB and Ethernet ports enable real-time monitoring and automated report export.
Airflow Uniformity: Dual centrifugal fans and precision baffles eliminate hot/cold or wet/dry zones.
Water-Saving: Closed-loop recovery recycles up to 80 % condensate, lowering operating costs.
Beyond Vibration, LIB Thermal Cycling Chambers with RF Shielding and CO₂ for Accurate Simulation
Modern applications demand more than just temperature and humidity control. LIB chambers expand testing capability with advanced add-ons:
RF Shielding
Attenuation: 60–90 dB across 30 MHz–6 GHz.
Standards: Compatible with IEC and ISO EMI requirements.
Ideal for testing 5G modules, IoT sensors, automotive ECUs, and other devices requiring protection from electromagnetic interference.
CO₂ Environmental Control
Range: 0–20 % CO₂, ± 0.4 % accuracy.
Applications: Tissue culture, microbial growth, seed germination.
Standards: Supports ISO 187 and ASTM D2247 protocols.
With these integrated modules, LIB's chambers simulate multi-factor stress environments-temperature cycling combined with vibration, humidity, RF isolation, or biological CO₂ regulation-making them versatile for research labs, certification agencies, and high-tech manufacturing floors.
How to Maintain a Thermal Cycling and Vibration Chamber
Keeping chambers in top condition is essential to maintain compliance and minimize downtime.
Routine Checks
Inspect door seals, hinges, and cable holes quarterly.
Check drains, water piping, and electrical connectors.
Calibration & Performance Validation
Verify ramp rates (3 ℃/min heating, 1 ℃/min cooling).
Confirm humidity stability within ± 2 % RH.
Conduct multi-point uniformity tests for temperature mapping.
Consumables & Components
Replace filters, tubing, and float switches periodically.
UV lamps (5,000 h) and xenon arc filters (1,600 h) require scheduled replacement.
Safety Systems
Test over-temperature, over-current, refrigerant pressure, and leakage protection.
Automatic shutdown prevents specimen or equipment damage during overload.
Durability by Design
Interior: SUS304 stainless steel-corrosion resistant and easy to clean.
Exterior: Powder-coated A3 steel for impact resistance.
Visibility: Full-height tempered-glass observation window with LED lighting.
Mobility: Lockable castors and leveling feet for easy repositioning.
