400×370×150 mm Size Bench Top Digital Rotational Viscometer with
ISO / CE Certifications
NDJ - 4 viscometer is suitable for determination of all kinds of
fluid viscosity and rheology, can determine mineral oil,
lubricants, adhesives, paint, fuel, printing ink, paint, cosmetics,
food, resin dynamic viscosity and structure viscosity and so on, it
is the petrochemical products, daily chemical, pharmaceutical,
food, fuel, adhesive and so on industry test fluid viscosity of the
NDJ - 4 viscometer working principle:
NDJ - 4 type rotary viscometer is suitable for determination of
various liquid and semiliquid absolute viscosity and rheological
properties. Widely used in the determination of oil, grease, paint,
food, medicine, cosmetics, adhesive, etc. Various kinds of fluid
viscosity. Is the new product development, product quality control
testing is used in the analysis of one of the most precise
1. Domestic other manufacturer rotational viscometer is completed
by straight rack/straight gear way, rack and pinion to work only a
tooth contact, if upward relaxed regulation; Will be down from
sliding, such as avoid from sliding, upward adjustment will be
difficult. And our rotary viscometer is adopt bevel gear way,
oblique rack and bevel gear worked three tooth contact, effectively
overcome straight rack/straight gear shortcomings, move convenient,
easy, and not from the slip. (oblique rack/bevel gear in the way of
processing requirements on cost than straight rack/gear way much
2. NDJ - 4 viscosity meter connection rotor outlet increased
Usually rotational viscometer rotor and the axis of rotation is
direct rigid connection, shaft different heart or rotor heart can
create different rotor in the test of rock, the impact test
precision. Axis sharp and fine and peak, is casual collision also
often cause pivot bending and even damage. After using the
universal interface can effectively reduce shaft and rotor
different heart bring test error, and protect pivot from impact and
damage. This kind of structure other domestic manufacturers also
no, only import high-grade viscometer seen the (universal joint
need import nc machine tool processing, precision requirements are
very high, the cost is also increased many).
3. NDJ - 4 viscosity meter change gear using high wear-resisting,
high performance engineering plastics pressing and become:
In order to make the rotational viscometer operation smooth,
measurement accuracy, the gear machining accuracy very high. At
present domestic other manufacturers viscosity meter used gear are
used in sheet metal processing into a tooth with other parts
riveting, due to the limitations of the processing methods, it is
difficult to meet the design requirements, make viscometer at work
doesn't run smoothly, such as jitter, shaking, pointer to beat,
etc., and noise. And our factory adopted high performance
engineering plastics (its performance is better than the metal)
will gear whole unit a pressing molding, because of the high
precision mold processing so as to ensure the gear fully meet the
design requirement, fundamentally solve the problem brought by the
metal gear, which makes the viscometer at work was very smooth,
improve the test precision.
4. NDJ - 4 viscometer processing fine, excellent performance:
Each component is carefully processing, elaborate debugging, and
strict quality control, as far as possible is the user happy to
buy, be at ease use.
