Following a full round of performance testing on a sample unit, a manufacturer based in Uzbekistan confirmed a purchase of Temperature Humidity Test Chambers from LIB Industry. The customer's evaluation covered temperature accuracy, humidity recovery speed, and long-term stability, and the results reinforced LIB Industry's standing as a trusted supplier of precision environmental testing equipment for laboratories across Central Asia.
【LIB Industry's Temperature Humidity Test Chamber Delivers Precision Performance】
LIB Industry's Temperature Humidity Test Chamber is engineered to sustain relative humidity up to 100% alongside a broad temperature
range from –20 °C to +100 °C, meeting the needs of laboratories running condensation testing, biological sample storage, and accelerated corrosion studies where standard chambers capped at 95% RH fall short.
The chamber is designed to comply with IEC 60068-2-78 for steady-state damp heat testing, IEC 60068-2-30 for cyclic damp heat, ASTM E104 for humidity generation using saturated salt solutions, and GB/T 2423.3 for the Chinese national equivalent. Temperature control relies on PT100 Class A sensors with 0.001 °C resolution paired with PID regulation, holding stability within ±0.5 °C. Humidity is generated through a steam-injection or ultrasonic system combined with dew-point sensing, maintaining accuracy within ±2.0% RH even at the 100% RH ceiling, where condensation risk is highest. Centrifugal fans distribute air multi-directionally, keeping spatial variation under ±1.5 °C so that every sample position experiences equivalent conditions.
During the customer's own 72-hour internal trial, the chamber sustained these conditions without significant fluctuation, matching the specification sheet across repeated test runs at temperatures and humidity levels the customer's product line requires.

Beyond hardware performance, several factors shaped the customer's decision to standardize on LIB Industry equipment across their
facility.
Safety compliance stood out first. The chambers carry CE marking, meet IEC 61010-1 electrical safety requirements, and can be configured to CSA standards for markets requiring North American certification, giving the customer confidence for both regional use and potential export applications.
Testing precision matched expectations, with temperature held within ±0.5 °C and humidity within ±2.0% RH across repeated trial runs, even at the demanding 100% RH setting. Cost-effectiveness was another deciding factor: compared to importing chambers from Western manufacturers, the customer achieved comparable specifications at a significantly lower total cost, without compromising on build quality, as interiors use SUS304 stainless steel and exteriors use coated A3 steel for corrosion resistance.
Customization played a major role in the final agreement. LIB Industry offered free-of-charge customization up to 2000 L internal volume, adjusting shelving, port placement, and program presets to match the customer's specific sample types, all included in the base quotation with no added engineering fee. Combined with a 3-year warranty and lifetime service support, the customer felt fully covered for long-term operation. On-site training was arranged for their technical staff, covering program setup, routine maintenance, and calibration verification, which the customer described as a highly practical and people-oriented service experience.
"Seeing a customer run their own full performance evaluation before committing to five units tells us our chambers hold up under real scrutiny, not just on paper," said LIB Industry's Director of Global Sales. "Our goal is always to combine precise engineering with a service experience that gives customers confidence long after installation."
