Thermo Scientific HAAKE Viscotester 7R plus

Thermo Scientific HAAKE Viscotester 7R plus

Version R: 20 - 40.000.000 mPas in 126 ranges (21 speeds with 6 spindles)

R for medium-viscous sub stances is the ”standard” viscometer for 80% of all viscosity measurements. It is especially suited for the medium viscosity range extending from
sewing machine oil up to PVC plastisols or whipped cream.
The measuring range is from 20 - 40 000 000 mPas

The Thermo Scientific HAAKE Viscotester 7 plus units can be used for tests and
comparative measurements for quality control according to recognized standards.

Measuring principle
The HAAKE Viscotester is a classical rotational viscometer that measures the resistance of a test substance against a pre set speed. The resulting torque or resistance measures the viscosity of the fluid. The higher the torque, the higher the viscosity. Due to the standardized geometry, the shear rates generated can only be determined precisely for Newtonian substances.

Compatibility
The basic ISO 2555 standard describes the design and the characteristic measuring technique of a viscosity measuring instrument (torque, speed, rotor geometry). If a rotational viscometer meets these requirements – as the HAAKE Viscotester 7 plus does – the results comply with the Brookfield method and are 100 %-compatible as long as comparable viscometer versions are used.

• Ready to go package – unpack, switch on and start measuring viscosity
• Digital display of viscosity, % torque, speed, spindle, upper viscosity limit
• Integrated automatic diagnostic functionality
• Visual and acoustic signals at critical measuring conditions

The Thermo Scientific HAAKE Viscotester 7 plus is supplied as a complete measuring unit consisting of the basic instrument, set of spindles with and a stable carry case

Serial No 390200709302

This instrument is on totally pristine condition, even no signs of wear on the case, as such we believe it may have been unused by the original owner. 3 Additional Brookfield spindles as per close up image.

Calibration is out of date at present, we can have the instrument calibrated and supplied with certificate for additional £220.00
