    Features
    • Top-exhaust design with a compact, balanced layout that makes better use of space, reduces installation constraints, and limits the impact on ambient temperatures.
    • Advanced noise reduction measures keep sound levels below 57 dB(A), similar to the volume of a normal conversation.
    • Wide operating range for temperature and humidity with consistently reliable performance.
    • High-precision control: temperature fluctuation within ±0.5 °C, temperature deviation within ±1.5 °C, and humidity deviation within ±3.0% RH.
    • Incorporates industry-leading ELV electronic expansion valve technology, allowing intelligent compressor power adjustment that cuts energy consumption by about 30% compared to traditional thermal expansion valves while extending compressor lifespan.
    Construction and Components
    • Stainless steel rack can be repositioned to fit samples of different heights. For heavier loads, optional reinforced shelves are available, supporting up to 80 kg per tier.
    • Side-mounted cable ports on both walls allow flexible connections for power or instrumentation from any direction. Multi-port configurations can also be customized to handle setups requiring a larger number of cables. Durable soft rubber plugs maintain a tight seal across a wide temperature range and have a long service life.
    • A large, clear observation window with multi-layer tempered glass and an anti-condensation heating element makes it easy to monitor samples throughout testing without fogging.
    • The interior is precision-welded with automated equipment and sealed using high-integrity gaskets to keep the chamber airtight.
    • For water supply, a dual tank system combines a fixed reservoir and a removable handheld tank that can be refilled during operation without interrupting the test process.

    Condensing method Air-cooled/water-cooled

    For air-cooled models, performance specifications are based on an ambient temperature of +25 °C and relative humidity of ≤85% measured with the chamber empty. For water-cooled models, reference conditions are an ambient temperature between +15 °C and +35 °C, relative humidity of ≤85%, and cooling water temperature of ≤+28℃, also measured without test samples inside the chamber.

    Start by thinking about the materials you need to test and the exact conditions you plan to recreate. Once you share those details with us, our team can suggest a test chamber that matches your testing process and performance targets.

    Yes. To maintain stable operation, it’s important to use purified water with controlled levels of resistivity, conductivity, and total dissolved solids (TDS). This helps avoid mineral buildup and keeps humidity readings accurate.

    Of course. If you need official verification, we can arrange calibration reports issued by certified third-party labs to confirm the test chamber’s performance.

    Both cooling methods are effective, but your choice depends on your facility layout and utility connections. If you’re unsure which one fits your environment best, our specialists will walk you through the pros and cons of each option.
