The DHT®ThermalAir-5000A is a high-performance thermal measurement device, specifically designed for scenarios requiring high precision and complex thermal performance testing. It offers an extended temperature range, enhanced data processing capabilities, and supports more detailed temperature differential and heat flux testing.
Precise Temperature Control System: Equipped with a fast and precise temperature control system, the temperature range spans from -80°C to +225°C, meeting a variety of experimental requirements.
Ultra-Fast Temperature Transition Rate: The temperature transition rate is extremely fast, with a transition time of less than 10 seconds from -55°C to +150°C, and also less than 10 seconds from +150°C to -55°C, significantly improving testing efficiency.
High Temperature Precision: The device provides a high temperature control precision of ±1°C, ensuring temperature stability during testing and minimizing the impact of temperature discrepancies on experimental results.
Adjustable Airflow Speed: The airflow speed range is from 4 to 25 SCFM, allowing flexible adjustments based on different testing needs, ensuring the accuracy of heat flux measurements.
Multiple Operating Modes: Two operating modes are available. The manual mode is suitable for heat/environment/cold cycles, while the program operation mode allows for setting the sequence of hot and cold cycles, offering greater flexibility and convenience for various testing scenarios.
