Length Comparator With Gauge

Length Comparator With Gauge About

The Length Comparator with Gauge is a precision laboratory instrument used for measuring the length change (expansion or shrinkage) of cement mortar, concrete, and other construction material specimens. It is widely used in construction material testing laboratories to assess the dimensional stability and durability of cement-based products.

This apparatus consists of a rigid frame fitted with a high-accuracy dial gauge or digital gauge, which measures minute changes in specimen length with high precision. It is designed to provide reliable and repeatable readings during long-term testing of specimens.

Manufactured using robust and corrosion-resistant materials, the Length Comparator ensures stability, accuracy, and long service life. It is suitable for routine laboratory testing as well as advanced research applications in civil engineering.

Key Features:

• High-precision dial/digital gauge for accurate readings
• Rigid and stable frame construction
• Measures minute expansion and shrinkage changes
• Corrosion-resistant and durable body
• Easy setup and operation
• Suitable for long-duration testing

Applications:

• Cement and mortar testing laboratories
• Civil engineering research institutes
• Construction material quality control departments
• Infrastructure development projects
• Academic and training laboratories

Working Principle:

The comparator measures the change in length of a test specimen over time using a high-sensitivity gauge system. Any expansion or shrinkage is recorded to evaluate the dimensional stability of the material.

Precision Measurement for Laboratory Testing

This length comparator excels at providing highly accurate measurements with its dial gauge, ensuring readings down to 0.001 mm. Designed for use with cement, mortar, and concrete specimens, it is essential for laboratories conducting compliance and quality assessments.


Robust Build and Reliable Alignment

Engineered with a heavy-duty cast iron frame and powder-coated finish, the instrument withstands rigorous laboratory conditions. Fine knurled screws and adjustable specimen supports ensure secure alignment and repeatable measurements every time.


Manual Operation, No Power Needed

Operated entirely by hand with a manual lever and precise dial gauge, this length comparator eliminates the need for a power supply. Its rapid response and instant measurement capability make it reliable for time-sensitive tests.
