3. Options:
①Enhanced ultra-low viscosity adapter（ULR）
Specially designed for measuring low viscosity fluids, there are two specifications to choose from: jacketed and non jacketed, with a minimum detection limit of 1cP, depending on the viscosity meter model used
② Temperature probe (temperature sensor)
usePt100rtd
Temperature measurement range:-20 – 300℃
Measurement accuracy:0.1℃
③ Data software
It is possible to control the viscometer through a computer and set various measurement parameters. Can display rheological curves of shear rate and viscosity.
The X-axis represents shear rate, and the Y-axis represents viscosity. For samples that undergo shear thinning, an increase in shear rate will cause a sharp decrease in viscosity.
④ Viscometer specific constant temperature bath DCW (N)series
Adopting high-performance single-chip microcomputer control, self-tuning PID regulation, imported Japanese platinum resistance,Imported Embraco（embrsco）Refrigeration compressorFast cooling, precise temperature control, and excellent temperature linearity throughout the entire temperature control range. Adopting a large backlit LCD display screen, all parameters are clear and concise, equipped with a thermocouple protection constant temperature liquid level protection device, which can effectively prevent instrument loss of control and heating tube burnout. The instrument works stably and reliably, and is easy to operate.
