About Standard Tar Visecometer

Electrical Heating with Immersion Heating Elements and Dimmer stat for controlling the temperature. Suitable for operation on 230 V, 50Hz, Single Phase, A.C. supply Complete with 10mm cup and valve. Cup, 10mm Ball Valve, 10mm.

Reliability and Standard Compliance

Manufactured as per IS: 1206, the Standard Tar Viscometer guarantees dependable and repeatable results for bitumen and tar viscosity analysis. Supplied with a calibration certificate, all key components are built with care-stainless steel for the bath and brass for the cup-meeting industry specifications and ensuring longevity in laboratory environments.

Precise Manual Operation

This viscometer operates in manual mode, utilizing a standard gravitational flow method for viscosity testing. A manual stopwatch enables efflux time readings down to 0.1 second resolution. With no digital interface, the instrument focuses on straightforward, reliable performance, with immediate response and hands-on control suited for laboratory technicians.

Built-In Safety and Ease of Use

Equipped with overheating protection in the stainless steel bath, the viscometer prioritizes operator safety. Accessories such as the receiver flask, valve key, thermometer, and stirrer are included, simplifying test setup and operation. The equipment's bench top design allows for convenient installation in standard laboratory settings.

FAQ's of Standard Tar Visecometer:

Q: How does the Standard Tar Viscometer measure tar and bitumen viscosity?

A: The viscometer measures viscosity by allowing a sample of tar or bitumen to flow through a brass cup with a standard 10 mm orifice at a controlled temperature. The efflux time (the time taken for 50 ml to flow out) is measured using a stopwatch, providing viscosity readings according to IS: 1206 standards.

Q: What is the correct process for conducting a viscosity test using this viscometer?

A: First, fill the stainless steel bath with water and heat it to the desired temperature using the built-in electric immersion heater. Fill the brass cup with 500 ml of the test sample, insert the thermometer and stirrer as supplied, and allow the sample to reach equilibrium. Open the valve and use the manual stopwatch to measure the efflux time for the sample to flow through the 10 mm orifice into the receiver flask.

Q: When should I recalibrate the Standard Tar Viscometer?

A: It is advisable to recalibrate annually or whenever there is any service, maintenance, or noticeable deviation in results. The equipment is supplied with a calibration certificate for initial verification, ensuring compliance with IS: 1206 requirements.

Q: Where can this viscometer be used?

A: This viscometer is designed for use in laboratories, particularly those engaged in quality control of road construction materials, research, or academic studies involving tar and bitumen. It is suitable for both governmental and private laboratory environments.

Q: What safety features are included in the viscometer?

A: The viscometer is equipped with an overheat protection mechanism in the stainless steel bath to prevent accidental temperature overshoots, ensuring safe operation during viscosity testing procedures.

Q: How accurate and fast is the measurement?

A: The viscometer provides immediate response as per the manual stopwatch reading, offering accuracy and resolution up to 0.1 second, which meets industry standards for viscosity testing of tar and bitumen.

Q: What are the key benefits of using this Standard Tar Viscometer?

A: Key benefits include compliance with recognized standards (IS: 1206), high-precision viscosity readings, ease of manual control, robust build quality, built-in safety, and inclusion of essential accessories for straightforward laboratory operation.
