Stop Measuring Viscosities the Hard Way Are you struggling with an expensive rheometer that only produces unstable results when testing low viscosity (e.g. below 100 mPa •s) samples? Drawing on A&D’s proven sensor technology for high-resolution analytical balances, the RV-10000A Tuning Fork Vibro Rheometer is a breakthrough alternative to conventional methods in the research of non-Newtonian fluid properties, especially for ease and precision in low viscosity measurements. Tuning Fork Vibro Rheometer Principle of Operation Spring Plate Displacement Sensor Electromagnetic Drive Temperature Sensor...

Advantages Wide Continuous Measurement Range—From 0.3 mPa • s The RV-10000A has a single viscosity detection system that can measure from very low to high viscosity without interruption (max. 0.3 to 25,000 mPa • s), which realizes high versatility and allows measurement of various types of fluids with just one instrument. It also allows continuous monitoring of viscosity variation with time, temperature as well as shear rate. ■ Extremely High Sensitivity The sensor sensitivity heightened through sharp resonance phenomena even detects viscosities around the level of water with unparalleled precision....

Easy Setup and Very Quick Measurement Compared with conventional methods, it takes much less time for you to set the sample fluid, start measurement, and obtain the viscosity value (the RV-10000A requires only 20 seconds to stabilize). Moreover, since the sensor plates have a very small thermal capacity, they cause minimal temperature change to the sample fluid upon immersion, also contributing to fast and stable viscosity measurement. It is very easy to clean the sensor after measurement as well – all you need to do is wipe off the sample residue with alcohol.* 2 In the case of sample fluid sticking...

RV-10000A – Main Section Water Jacket Positioning Stopper A water jacket is provided as standard to be used in conjunction with a commercially available temperature control tank to control the sample fluid temperature. This stopper both protects the thin sensor plates from accidental dropping and helps bring them to a uniform height quickly to start a measurement. Titanium Sensor Plates and Temperature Sensor The X-Y-Z stage allows fine positioning of the sample cup in three directions so as to set the sensor plates correctly in the sample fluid every time. The titanium is anti-corrosive and resistant...

Auto Mode Program Mode Measurement Examples Purified water (Auto mode - Quick) In Auto mode, the sensor plate amplitude automatically goes from 0.07 mm to 1.2 mm and back to 0.07 mm again according to one of three preset types of measurement conditions: Quick, Standard and Fine modes, from which you can make a choice of how finely to change the amplitude (8, 13 or 114 levels) and how long to take for the measurement (7.5, 25 or 60 minutes in total). Auto mode helps when you want to take a quick scan of the physical properties of the sample fluid. Program mode allows you to more freely design the measurement...

Also available... Tuning Fork Vibro Rheometer - Basic Model The sensor plate amplitude is alterable to eight levels (0.07 / 0.1 / 0.2 / 0.4 / 0.6 / 0.8 / 1.0 / 1.2 mm) by manually pressing a key on the display unit. The viscosity and temperature data can be sent to a PC for real-time graphing* 5 using the provided “WinCT-Viscosity” software (as the basic model comes with no special controller). * 5 The amplitude/shear rate cannot be used as an axis variable.
