A&D SV-10, Viscometers 0.3cP - 10,000 cP

SV-1A: 0.3..1000mPa..s (cP), SV-10A: 0.3..10000mPa..s (cP), SV-100A: 1000..100000mPa..s (cP)]. Simultaneous Measurements of Temperature and Viscosity It is widely known that viscosity is very temperature dependent (–2~–10%/°C). The SV-A series has a temperature sensor (0~160°C) right next to the viscosity sensor plates, enabling users to easily monitor the relationship between viscosity and temperature. Sample Temperature Control A water jacket is provided as standard to be used in conjunction with a commercially available constant heat water tank to heat the circulating system. This ensures that the sample remains at a constant temperature and that the temperature can be changed for viscosity measurement (0 ~ 100°C). Standard Windows Communication Tools WinCT-Viscosity and a Serial-USB Converter The graphing program RsVisco receives the viscosity and temperature data from the SV-A series and creates a graph on a personal computer in real time. As such, changes in viscosity and temperature over time as well as the correlation between viscosity and temperature can be observed visually. Example Applications: Measure the viscosity necessary for the correction of particle size distribution Control the viscosity of resist liquids, inks, coating materials, adhesives, etc. Control the viscosity of abrasives for semiconductors, ceramic materials, etc. Measure the cure processes of polymers, soldering flux, proteins, and gelation point, etc. Detect the cloud points of nonionic surface-active agents Measure viscosity variation due to changes in temperature of a lubricant, engine oil, food, etc. Quantify the physical properties of biological substances, such as blood, etc.   Tuning-fork Vibration Viscometer The tuning-fork vibration viscometer has a pair of thin sensor plates of the same natural frequency, which are driven with electromagnetic force to vibrate at the same amplitude. The viscidity produced between the sensor plates and the sample liquid is detected based on the amount of electronic current required to drive the sensor plates and maintain them at a constant amplitude. The vibration viscometer is accredited as a Japan Calibration Service System (JCSS) standard device by the National Institute of Technology and Evaluation (NITE), along with the capillary viscometer and the rotational viscometer. The sensor plates have very small thermal capacity and cause only minute displacement in the sample liquid, which prevents changes to the temperature and the physical properties of the sample. Since the two sensor plates vibrate in reverse phase, it is possible to measure the viscosity of a sample while flowing or being stirred.   Very Quick Measurement The initial viscosity coefficient will be indicated just 15 seconds after starting the measurement. The measured values will then be displayed in real time in response to the changes in viscosity. High Accuracy The SV-A series achieves an excellent repeatability of 1% of reading over its full measurement range. Low Viscosity Measurement No other viscometer is capable of measuring viscosity from as low as 0.3mPa..s.(SV-1A/10A) Easy Calibration Both one-point and two-point calibrations are possible using either viscosity standard liquids (optional) or samples of known viscosities. Simplified Calibration function, a one-key operation that utilizes purified water is also available for the SV-1A/10A. Clearly Visible Display Easy-to-read VFD for viscosity and temperature. Only 6 keys for simple operation. Portable Sensor Unit The sensor unit can be detached to perform measurements on location at a manufacturing factory, field research, etc. A portable carrying case is also provided as standard.
