CANNON MANNING / FENSKE VISCOMETER
HT-715
Reference Standards: IS 1206 (Part II & III)
This viscometer system is used for determining absolute and kinematic viscosity of bitumen and petroleum products using capillary flow under controlled temperature and vacuum conditions.
The method involves measuring the time taken for a liquid to flow through a calibrated glass capillary tube. The viscosity is calculated using flow time and calibration constants.
The system is widely used in advanced laboratories for high-precision viscosity measurement.
Key Features
- Dual functionality (absolute & kinematic viscosity)
- Vacuum-assisted testing
- Multi-sample bath (up to 4 tests)
- Digital temperature control
- High accuracy and repeatability
Technical Specifications
- Temperature range: -20°C to 300°C
- Vacuum: Up to 650 mm Hg
- Bath: Double layer with stirrer
- Power: 230V

Note: Viscometer tubes can be ordered separately in various sizes at additional cost.
Solvent Recovery Unit
On-flammable solvent liquids used for the binder extraction test can be successfully recovered using the solvent recovery unit.
The recovery unit consists of two stainless steel chambers, one for the dirty used solvent and the other for the cleaned recovered solvent. Solvent in the left-hand side chamber is distilled by an electrical heater and then passes through a water cooling system and drops into the second chamber ready for re-use. A temperature switch automatically stops the heating elements when the recovery process is completed. The unit is supplied complete with 10 m plastic tubing, tube clamps, sieve insert 0.6 mm opening and one lid.
The solvent recovery unit is supplied complete with:
- Plastic tubing, 10 m
- Sieve insert, 0.6 mm
- Tube clamps
- Lid

STANDARD TAR VISCOMETER (4 mm & 10 mm)
HT-713 & HT-714
Reference Standards: IS 1206 (Part I), IP 72, BS 2000
The Standard Tar Viscometer is used to determine the viscosity of bitumen, tar, and cutback bitumen by measuring the time taken for a fixed volume of sample to flow through a standard orifice.
The test is based on gravity flow principle, where viscosity is proportional to the time required for efflux through the orifice. The apparatus includes a heated bath, test cup with valve, and temperature measurement system.
This equipment is essential for evaluating flow characteristics and application behavior of bituminous binders in road construction.
Key Features
- Chrome plated copper bath
- Electric heating with dimmerstat
- Precision orifice cups (4 mm or 10 mm)
- Stirrer with insulated handle
- Stable structure with leveling
Technical Specifications
- Temperature range: Ambient to 200°C
- Cup sizes: 4 mm or 10 mm
- Heating: Electric
- Power: 230V
