Low Temperature Constant Temperature Overflow Water Tank for Asphalt Mixture Density Test (±0.1℃ Precision)

Precise Temperature Control: Adopts a high-precision intelligent temperature control system with a temperature control range of 0℃~60℃ (low temperature range) and a precision of ±0.1℃. It can stably maintain the low-temperature environment required for asphalt density tests, avoiding data distortion caused by temperature fluctuations, and fully complies with industry standards such as JTG E20-2011 and JTG3410-2025.

Efficient Temperature Control System: Equipped with a 1000W heating device and a 550W refrigeration compressor unit, it features fast heating/cooling speed to quickly adapt to different test temperature requirements, meeting various asphalt density test conditions such as surface method, water weight method, and wax sealing method.

Stable Overflow Design: The built-in forced circulation system ensures uniform water temperature in the water tank; the automatic overflow device can stably maintain the test water level, ensuring a fixed water level for the specimen and basket when immersed in water, and guaranteeing the standardization of test operations and data repeatability.

User-Friendly Operation: The digital temperature control panel is easy to operate, supporting one-click temperature setting and independent control of circulation switch/heating/cooling, adapting to the high-frequency use needs of laboratories; the whole machine is made of wear-resistant and corrosion-resistant materials, with a flat and stable tabletop that can directly install a hydrostatic balance, matching the supporting use of conventional asphalt testing instruments.

Multi-Scenario Adaptation: In addition to asphalt mixture density tests, it can also be used for sample constant temperature tests in petroleum, chemical, biological and other fields, with one machine for multiple uses and outstanding cost performance.
