What is a benchtop environmental chamber? It is a compact, high-precision environmental simulation system specifically designed for laboratories or workbenches with space constraints. Within a limited footprint, it can simulate a wide range of temperature and humidity conditions to test product or material performance, stability, and service life under specific environments.
Despite its smaller size (typically with an internal volume of 0.3 to 0.8 m³), the benchtop chamber offers precise environmental control and is widely used in electronics, electrical engineering, automotive, medical, materials science, and R&D applications.
As environmental simulation testing becomes an increasingly critical component in product reliability validation, benchtop chambers are gaining popularity in R&D labs, quality control departments, and academic institutions due to their compact size and integrated functions. Especially in scenarios where space is limited but high accuracy and stability are required, DHT®’s benchtop environmental chamber embodies the philosophy of “compact yet powerful,” striking an optimal balance between performance and form factor.
-
Precise Environmental Control: No Compromise on Core Performance
Equipped with DHT’s self-developed DHSPLCON™ intelligent control system, the chamber delivers excellent performance in temperature and humidity control, making it ideal for sensitive product testing in electronics, medical devices, and aerospace materials.
-
Wide temperature control range: Standard models cover -40°C to +150°C, with optional configurations extending to -70°C or higher.
-
Accurate humidity control: Relative humidity range from 20% RH to 98% RH, with fluctuation kept within ±2.5% RH.
-
Fast control response: Temperature change rates up to 1.0°C/min (heating/cooling), compliant with IEC, MIL, and other international standards.
-
Excellent uniformity: Optimized airflow circulation and high-precision Pt100 sensors ensure consistent environmental conditions with no dead zones.
These specifications allow the DHT® benchtop chamber to meet rigorous testing standards while remaining a compact and reliable alternative to traditional large-scale test chambers—ideal for tabletop use.
-
Compact and Modular Design: Space Saving Without Sacrificing Efficiency
Understanding the spatial limitations of modern laboratories, DHT® emphasizes structural integration and function modularity in its design philosophy.
-
Minimal footprint (<0.5 m²): The entire unit fits comfortably on workbenches, standard test tables, or instrument racks.
-
Modular system layout: Refrigeration, electrical control, and test chamber components are independently partitioned for easier maintenance and future upgrades.
-
Low-noise operation: Equipped with low-noise compressors and vibration-damping fans, the overall noise level is below 65 dB—suitable for quiet lab environments.
-
User-friendly interface: A 7-inch touchscreen display with intuitive programming and data export capabilities ensures smooth and accessible operation.
These thoughtful design features enhance user experience and ensure long-term reliability, even under high-frequency, high-load testing scenarios.
-
