Product Description
The Digital Small Sample Viscometer models YR05840, YR05841, and YR05842 from Kalstein stand out in the laboratory equipment market due to their precision and advanced technology. Designed for accurate measurements of viscosity across a wide range of values, these viscometers are an essential asset for any lab requiring reliable readings.
The measurement range varies by model, with the YR05840 measuring from 6.4 to 2 million mPa.s, the YR05841 from 12.8 to 4 million mPa.s, and the YR05842 from 51.2 to 16 million mPa.s. Each model supports 18 different speeds ranging from 0.5 to 100 r/min, using standard rotors No.21, 27, 28, and 29. An optional ultra-low viscosity adapter (rotor No.0) with a separate heating furnace is available for specialized measurements.
This product is distinguished not only by its precision—with a test error of ±2% for Newtonian liquids—but also by its excellent repetitive error rate of ±1%. The temperature control is precise to within 0.1℃, maintaining stable conditions to ensure the accuracy of results. Interfacing with other devices is straightforward thanks to the dual RS232 interfaces, making data transfer and integration seamless.
