Constant Temperature Waterbath for Marshal Test with Digital Controller: An In-Depth Description

Overview

The Constant Temperature Waterbath for Marshal Test with Digital Controller (Model: EIE-174) is a sophisticated laboratory apparatus explicitly designed to comply with both national and international standard procedures for the Marshal test, an essential method in asphalt testing. Precision-engineered by EIE Instruments, this waterbath showcases a state-of-the-art design and incorporates a suite of advanced features to ensure optimal performance, reliability, and ease of use.

Key Features

Double-Walled Construction

The waterbath features a double-walled construction, ensuring excellent thermal insulation and durability.

• Inner Chamber: The interior of the waterbath is crafted from mirror-polished stainless steel (SS-304 Grade), providing a smooth surface that is corrosion-resistant and easy to clean.
• Exterior Body: The outer body of the waterbath is fabricated from robust mild steel material, powder-coated in attractive shades to enhance aesthetic appeal and provide resistance against environmental factors.

Glass Wool Insulation

To prevent thermal heat loss and enhance energy efficiency, the gap between the inner chamber and the exterior body is packed with high-quality glass wool insulation. This feature ensures that the heat remains well-contained within the bath, maintaining a consistent temperature and conserving energy.

Temperature Control

Precision temperature control is a hallmark of this waterbath.

• Temperature Range: The equipment supports a temperature range from 5°C above ambient to 100°C.
• Temperature Accuracy: This range is maintained with an impressive accuracy of ±0.5°C, ensuring repeatable and reliable test results.
• Digital Controller: The microprocessor-based auto-tune digital temperature controller cum indicator is a standout feature, allowing users to set and monitor the temperature effortlessly with pinpoint accuracy.

Uniform Temperature Distribution

To ensure uniform temperature distribution within the bath chamber, a constant speed stainless steel stirrer is integrated into the design. This stirrer continuously circulates the water, eliminating hotspots and maintaining a consistent temperature throughout the chamber.

Dimensions and Capacity

• Working Size: The waterbath has a working dimension of 15" x 15" x 6", providing ample space for test samples.
• Test Accommodation: It is designed to accommodate at least three 6" diameter (150 mm) Marshal moulds, along with the breaking head assembly on its heavy-duty platform.

Compliance and Standards

The Constant Temperature Waterbath for Marshal Test with Digital Controller meets rigorous national and international standards, ensuring that it is suitable for a wide range of laboratory environments and procedural requirements.

Applications

This waterbath is specifically tailored for Marshal testing in asphalt laboratories, making it an indispensable tool for quality control and research in the field of civil engineering and road construction. Its robust construction, precise temperature control, and uniform heating capabilities make it suitable for other laboratory applications that require controlled thermal environments.

Safety and Maintenance

For added safety, the equipment is designed with user-friendly features that facilitate ease of use and maintenance:

• Safety Features: The sturdy construction and high-quality materials used in fabrication ensure durability and long-term performance.
• Ease of Maintenance: The polished stainless steel inner chamber is easy to clean, preventing contamination and ensuring consistent test results.
