Accurate Measurement for Bituminous Materials

Designed to deliver precise viscosity readings of tar and bitumen, this viscometer features a standard 10 mm orifice and a single specimen capacity of 50 ml. The thermostatic water bath ensures uniform test conditions, complying with IS:1206, essential for consistent laboratory results in material testing.

Robust Construction for Longevity

Quality materials, such as the stainless steel orifice cup, mild steel frame, and brass orifice, coupled with a powder-coated finish, provide excellent corrosion resistance and long service life. The bench-top design makes it suitable for any standard laboratory environment.

Easy-to-Use Manual Control

Manual operation via adjustable valve and stopwatch timing allows users to closely monitor each test. The instrument features a bubble level indicator to ensure proper alignment, promoting repeatable results and straightforward setup for lab technicians.

FAQ's of Tar Viscometer:

Q: How is the viscosity of tar and bitumen measured using this viscometer?

A: The tar viscometer measures viscosity by allowing a 50 ml sample to flow through a standard 10 mm orifice cup under gravity. The time taken for the sample to pass through is recorded with a stopwatch, providing a viscosity reading according to IS:1206 specifications.

Q: What materials are used in the construction of the Tar Viscometer for durability?

A: The viscometer is constructed with a stainless steel orifice cup, mild steel frame, and brass orifice. Its powder-coated finish enhances corrosion resistance, extending the instrument's operational life in laboratory settings.

Q: When should this viscometer be used in testing procedures?

A: This viscometer is ideal for use when determining the viscosity of road tar and bitumen in laboratory quality control and research applications, especially where accurate compliance with IS:1206 is required.

Q: Where is the Tar Viscometer typically installed for operation?

A: The device is designed for bench-top installation within laboratories that test bituminous materials. Its compact form and 15 kg approximate weight facilitate easy placement and secure operation.

Q: What is the process for conducting a test with this equipment?

A: Start by preparing a 50 ml tar or bitumen sample and filling the orifice cup. Set the water bath to the desired temperature using the thermostat. Use the valve key to release the sample and measure the flow time with a stopwatch. Record data for analysis.

Q: How does the thermostatic control benefit the testing process?

A: Thermostatic control maintains precise and uniform water bath temperature during testing. This is crucial for reproducibility and accuracy, ensuring that viscosity readings are reliable and consistent across multiple specimens.

Q: What are the advantages of using manual control for this viscometer?

A: Manual control offers flexibility and direct supervision of the testing process, allowing users to adjust the valve for uniform gravity flow and monitor timing exactly. This hands-on approach ensures dependable and repeatable measurement outcomes.
