Accurate climate simulation is required to verify the dependability of modern industrial products in harsh circumstances. The Temperature Humidity Chamber is an important tool for businesses in a variety of industries including electronics, automotive, pharmaceutical and materials research. These environmental test chambers simulate temperature and humidity changes precisely, to evaluate product resistance to thermal shock, humidity and combined climate cycling. Whether you're testing electronic components for moisture resistance, or assessing polymer degradation rates, a quality product provides the controlled environment that allows for repeatable, standards-compliant testing, helping to prevent costly field failures.

Most temperature and humidity test chambers perform adequately at standard conditions but fail at challenging specifications like 10°C/20%RH. This capability defines equipment class. We deploy Electronic Humidity Sensor & Dew Point Control technology instead of outdated wet-bulb methods that lose accuracy below 15°C. Our advanced dew point PID algorithm maintains ±2.5% RH stability even during low-temperature low-humidity cycles—the most demanding operational envelope.
Your temp humidity chamber should never compromise test integrity through humidity fluctuation. Our independent boiler generates pure steam delivered through insulated pipework, providing instantaneous humidity response without the lag, overshoot, and mineral contamination inherent to shallow-pan evaporation systems. This architecture ensures your climatic chamber maintains target conditions throughout programmed cycling.
Sample contamination from condensate dripping ruins expensive prototypes and invalidates test runs. We engineered four protection layers:
· 45° Sloped Drip Tray: Directs ceiling condensation to collection channels, preventing droplet fallback onto specimens
· SUS304 Fully Welded Interior: Rivet-free, seamless construction eliminates rust and moisture penetration pathways
· Hermetic Scroll Compressor: German-engineered sealed unit with R404A/R23 refrigerant sustains 1,000+ hour continuous operation at 35°C/85%RH without performance degradation
· Double-Layer Magnetic Door Gasket: Creates airtight barrier preventing ambient humidity infiltration during testing
Your programmable temperature humidity chamber meets critical verification protocols:
· IEC 60068-2-78: Damp Heat, Steady State
· IEC 60068-2-30: Damp Heat, Cyclic
· JIS C 60068-2-78: Japanese Moisture Testing (supplier audit requirement)
· ISO 16750-4: Automotive Electronics Environmental Validation

Unusual chamber dimensions, custom port configurations or unique programming requirements? Our engineering team creates temperature humidity environmental chamber systems appropriate to your test methods and facility limits.
Q: Why does my temperature moisture chamber show humidity overshoot during heating cycles?
A: Built-in pan systems cannot modulate fast enough. External boiler humidification with proportional steam injection solves this.
Q: What water type should I use in the temp and humidity test chamber?
A: Always use deionized or distilled water (resistivity >500 Ω·m). Tap water causes sensor fouling and heater scaling.
Q: How is temperature ramp rate calculated?
A: Per IEC 60068-3-5, it's the average linear change rate. Verify whether specs cite average or peak minute rates.
Q: Can the chamber test powered electronic devices?
A: Yes, but you must calculate device heat dissipation. Refrigeration capacity must exceed internal load to maintain setpoint temperatures.
Q: How often does sensor calibration occur?
A: Capacitive humidity sensors require annual recalibration. Our built-in verification feature simplifies this compliance requirement.
