If you’re seeking a small, reliable, and affordable environmental test chamber that doesn’t occupy your entire lab, the LIB industry TH-50 and TH-80 Desktop Climatic Test Chambers are the perfect solution. These hot-selling units are designed for laboratories and R&D centers requiring precise temperature and humidity control, combining compact size, stability, and ease of operation.
With a temperature range from –70 °C/–40 °C/–20 °C to +150 °C and humidity control from 20% to 98% RH, stability of ±0.5 °C and ±2% RH ensures repeatable results. Its benchtop design enables efficient testing in limited lab space, ideal for small-batch R&D, calibration, and accelerated environmental simulations.
Unlike bulky walk-in environmental chambers,by fitting directly on a workbench, the desktop climatic test chamber enables efficient testing without occupying large laboratory areas.
A compact desktop climatic chamber TH-50 is testing electronic components in the customer's lab.
The LIB industry portable climatic test chamber is versatile, supporting multiple laboratory applications while complying with international standards:
Calibrate temperature and humidity sensors, thermometers, and hygrometers.
Standards: IEC 60068-3, ISO 17025.
Simulate controlled environmental conditions to assess product or material stability over time.
Standards: ASTM D4332, IEC 60068-2-1/-2-2.
Prepare materials or components under defined temperature and humidity before main testing.
Standards: ISO 554, IEC 60068-2-78.
Support microbial, biochemical, or material conditioning processes under controlled climates.
Standards: ASTM E104, ISO 11133.
Conduct accelerated environmental tests to evaluate durability and performance under temperature and humidity cycles.
Standards: IEC 60068-2-38, ASTM D4332.
This structured approach allows laboratories to immediately understand the chamber’s capabilities and compliance, making it suitable for R&D, QA, and lab standard compliance.
The precision of temperature and humidity control in a small climatic test chamber comes from the synergy of high-accuracy environmental sensors, intelligent control systems, uniform airflow, and rapid cooling mechanisms. These elements ensure stable conditions, delivering reliable results for stability testing.
Key factors contributing to precision include:
Combines a PT100 platinum resistance thermometer with an advanced humidity sensor in a single unit. Detects temperature fluctuations as small as ±0.001 °C.
Maintains humidity accuracy within ±2% RH.
Enables real-time monitoring of environmental conditions for consistent test results.
