NIRUN RDV-T1 digital display Rotational Viscometer is a viscosity temperature temperature control all-in-one machine, which integrates viscosity measurement and precise temperature control in one. It breaks through the existing market that has a constant temperature Water Tank, a viscosity measuring instrument, and a small amount of sample adapter to form a split machine.
1. The all-in-one viscosity measurement system is composed of a small sample adapter (SSR) cylindrical sample sleeve and SC4 rotor, which can be accurately measured at a certain shear rate. The sample volume only needs 2 to 16m, and the SC4 rotor is cylindrical The geometry provides very accurate viscosity measurements.
2. The small sample cylinder is easy to load and unload, which brings convenience to the cleaning work.
3. The small-volume sample cylinder is closely connected with the temperature controller, which can accurately keep the temperature of the sample.
4. The stirring action of the rotor, coupled with the small amount of sample, can minimize the inhomogeneity of the sample temperature. The constant temperature time is greatly shortened.
5. Controlling the temperature when measuring the viscosity helps to ensure the accuracy of the experimental results. Since the temperature controller is composed of a semiconductor and a built-in automatic optimization temperature program control, the temperature control accuracy reaches ±0.1°C.
6. The temperature control is operated by DV-T1 data acquisition and drawing analysis software, which has good operating performance and flexibility.
