Viscometer Automated Digital Model ZNN-D6C, ZNN-D12B (NRC-130, NRC-132), 6 and 12 speeds

Models NRC-130, NRC-132 electric viscometers are a new type direct indicating instruments, this is a doddle to control with its well-designed on-screen,the intelligence Single-Chip Computer system is commissioned in instruments which are available in 6 and 12 speed designs for use on either 50 Hz and 60HZ electrical power. The standard power source is 220 volts.

The Viscometer can measure all kinds of rheological parameter, draw flow curve according to the multipoint measure data, determine the flow pattern of liquid during flow behavior, choose the proper formula and take the comparatively accurate measurement for non-Newtonian fluid. It has the characters of simple operation and high accuracy. It applies to viscosity measurement of drilling fluid in all the big oil fields, scientific research institutions and laboratories and it also applies to geology, chemical industry, coal, wine making and etc.

The test fluid is contained in the annular space or shear gap between the cylinders. Rotation of the outer cylinder at known velocities is accomplished through precision gearing. The viscous drag exerted by the fluid creates a torque on the inner cylinder or bob. This torque is transmitted to a precision spring where its deflection is measured and then related to the test conditions and instrument constants. This system permits the true simulation of most significant flow process conditions encountered in industrial processing.

Direct Indicating Viscometers combine accuracy with simplicity of design, and are recommended for evaluating materials that are Bingham plastics.

Model ZNN-D6C (NRC-130) Viscometers are equipped with factory installed R1 Rotor Sleeve, B1 Bob, F1 Torsion Spring, and a stainless steel sample cup for testing according to American Petroleum Institute Specification RP 13B.

Model ZNN-D6B (NRC-132) Automated Digital Rheometer measures rheological properties of Newtonian and non-Newtonian fluids.

This rheometer is equipped with R1 Rotor Sleeve, B1 Bob, F1 Torsion Spring, and a stainless steel sample cup for testing according to American Petroleum Institute Recommended Practice.

Viscometer Models NRC-130, NRC-132 are designed instead of old ones: NRC-35D, NRC-12D.
