The overflow-type multi-functional low-temperature water bath is a constant temperature device designed specifically for highway laboratories.It is particularly suitable for compacted asphalt mixture density testing(surface-dry method)and asphalt mixture theoretical density testing(vacuum method).

Laboratory Circulating Water Bath

Model:LQJHY-1

I.Product Introduction

This equipment employs advanced circulating temperature equalization technology to achieve stable and uniform temperature distribution and precise control.Its overall performance meets the requirements of the Ministry of Transport's JTG E20-2011 standard,and its design and performance evaluation reference ASTM E715,"Standard Specification for Gravity-Convection and Forced-Circulation Water Baths."This equipment is widely used in highway engineering,building materials testing,petrochemicals,and other fields,and is particularly suitable for asphalt mixture density determination and isothermal testing requirements.

II.Product Feature

Transparent Water Tank Design:Equipped with two large 265mm×265mm observation windows for easy real-time observation of sample status during experiments.

Omnidirectional lighting system:Built-in water tank lighting eliminates blind spots and ensures the accuracy of experimental data.

Dual-circulation pump system:The equalization circulation and overflow circulation are independently controlled to avoid temperature fluctuations and ensure that there are no temperature dead zones in the water tank.Temperature non-uniformity≤±0.1℃,high temperature control accuracy.

Composite Sealing Top Cover:Employs a three-tiered sealing structure for effective insulation and reduced heat loss.

Modular Accessories:Can be combined and disassembled to form various specialized constant temperature water tanks to meet different experimental needs.
