Key Benefits: Precision, Efficiency, and Safety for Your Lab

Our Rapid Temperature Change Test Chamber is more than just a piece of equipment; it is a solution designed to address the real-world challenges you face daily. We have focused on core features that deliver tangible benefits, enhancing your lab's productivity and the reliability of your outcomes.

• Up to 20°C/min Linear Ramp: Compresses what would be a 3 to 5 hour gradual test into a much shorter cycle, without sacrificing the linear profile that standards require. This directly solves the common pain point of time-consuming test cycles, giving you faster results without compromise.

• Temperature Plus Optional Humidity: Run dry heat or cold cycling, or add humidity control from 20% to 98% R.H. without buying a second chamber. This engineering excellence is a hallmark of ASLi's 28 years of manufacturing experience. You can see their full capabilities at https://www.aslitesting.com/.

• ±0.5°C / ±2.5% R.H. Control Accuracy: BTHC-based control keeps both temperature and humidity stable, including during high-speed ramp events where drift usually appears, ensuring reproducible outcomes across every run.

• Four Standard Volumes, A~F Configurable: 150L, 225L, 408L, and 800L internal sizes, each configurable across A~F option levels, from basic cycling to full humidity control. This flexibility means one chamber series can serve multiple testing protocols, making it a cost-effective investment for your facility.

• Programmable Multi-Segment Cycling: Up to 100 programs, each with up to 100 segments, and maximum 999 cycles per program. Power-off memory resumes from where the program stopped after power loss, with 5-year memory backup.

• Comprehensive Safety Protection: Multi-layer protection includes fuse-free switch, compressor overload protection, high/low pressure coolant switch, over-humidity protection, over-temperature protection, fault warning system, and water shortage warning, ensuring a safe working environment.

Solving the Problems That Slow Lab Work Down

We know the frustrations that come with routine thermal cycling testing. The Rapid Temperature Change Test Chamber is built to eliminate them.

• Struggling with slow ramp rates extending test cycles? Linear control from 3 to 20°C/min and nonlinear control from 3 to 30°C/min let you match the ramp profile to your test standard, compressing test time without sacrificing accuracy.

• Concerned about inconsistent temperature and humidity affecting test validity? The BTHC control system maintains ±0.5°C and ±2.5% R.H. control accuracy, ensuring reproducible outcomes across every run, even during high-speed ramp events.

• Tired of time-consuming setup and monitoring? The LCD interactive touch-screen controller and programmable multi-segment cycling allow for precise parameter setting and unattended operation, streamlining your testing process.
