Advantages of the Benchtop Environmental Chamber
1. Compact, Space-Efficient Benchtop Design: With overall dimensions of 820 × 1160 × 950 mm, the TH50 benchtop environmental test chamber fits easily beside laboratory benches or beneath fume hoods. Its compact footprint helps laboratories optimize valuable floor space while still delivering full environmental testing functionality. The small form factor does not compromise performance, making it suitable for both research and industrial applications.
2. Wide-Range Temperature and Humidity Control: This small benchtop test chamber provides comprehensive environmental simulation, covering temperatures from –86 °C to +150 °C and humidity levels from 10 % to 98 % RH. A high-performance compressor-based cooling system combined with electric heating enables accurate testing under extreme cold, high heat, and high-humidity conditions. It is ideal for electronics, materials, and battery testing in realistic operating environments.
3. High Precision and Excellent Uniformity: Equipped with PT100 Class A sensors offering a resolution of 0.001 °C, the chamber ensures highly accurate control of temperature and humidity. Advanced PID algorithms maintain temperature stability within ±0.5 °C and humidity within ±2 % RH. A centrifugal airflow system evenly distributes conditioned air, eliminating hot or cold spots and ensuring consistent exposure for all test samples.
4. Fast Thermal Cycling Capability: The chamber supports cooling rates of up to 1 °C/min and heating rates of 3 °C/min, allowing faster test cycles and improved productivity. Programmable controllers enable hundreds of steps to be stored in a single test profile, reducing setup time and streamlining complex testing procedures for higher throughput.
5. Robust Construction and Integrated Safety Protection: The interior chamber is manufactured from SUS304 stainless steel, providing excellent corrosion resistance in high-humidity environments. The exterior features a 4 mm A3 steel frame with durable powder coating for long-term industrial use. Multiple safety protections—including leakage current protection, grounding, phase monitoring, and over-temperature shutdown—ensure safe and reliable operation throughout demanding test cycles.
6. Ultra-Low Noise Performance: The benchtop environmental chamber operates at ≤60 dBA, producing less noise than typical office equipment. Even during intensive temperature and humidity cycling, it maintains a quiet working atmosphere, minimizing interference with precision experiments, collaborative discussions, and online meetings. This low-noise design makes it an excellent choice for laboratories, research centers, and cleanroom environments where acoustic stability is essential.
