Overview
The NIRUN RDV-T2 digital Viscometer is an all-in-one viscosity and temperature control device that integrates viscosity measurement and precise temperature control. It uses a Small Sample Adapter (SSR) system consisting of a sample sleeve and an SC4 rotor. It requires only 2-16ml of samples to make accurate measurements at specific shear rates. Its cylindrical geometry ensures the accuracy of viscosity data and shear rates. The all-in-one design simplifies the complex structure of traditional split systems (thermostatic sink, Viscometer, adapter). The sample cartridge is easily loaded and cleaned, and it is tightly connected to the thermostat. Combined with the rotor Stir and a small number of samples, it can quickly even the sample temperature and significantly reduce the thermostatic time.
The device achieves precise temperature control (accuracy +/- 0.1 ° C) through semiconductor temperature control and built-in optimization program, and the lifting temperature is adjustable, which facilitates the study of sample performance through temperature changes. Viscosity measurement is operated by DV-T2 data collection and programmable analysis software, which supports rheological Linear dispersion analysis, improving experimental accuracy and operational flexibility.

Principle
The RDV-T2 digital Viscometer works on the principle of swirl/spin viscosity measurement. The instrument drives the SC4 rotor to swirl/spin in a small sample sleeve filled with samples. The viscosity of the sample is calculated by measuring the torque subjected to the rotor swirl/spin in the fluid. The process is carried out at a certain shear rate, and the cylindrical geometry ensures the accuracy of the shear rate. At the same time, the integrated temperature control system precisely heats or chills down the sample sleeve through semiconductor elements and a built-in optimization program. The sample temperature is controlled within the set range (-1 ° C to 150 ° C) with an accuracy of +/- 0.1 ° C. Stir action of the rotor combined with a small amount of samples accelerates heat transfer and makes the sample temperature uniform quickly. The measurement data can be processed by a microcomputer control system, and can be collected, programmed and analyzed by DV-T2 software.

Notice
Please use a power supply that meets the specifications (AC100-240V, 50/60Hz or DC17V 1.2A).
* When selecting the rotor model and setting the speed, ensure that the measurement value is within the instrument range (25~ 10,000,000 mPa · s).
* The sample volume should be controlled within the range of 2-16ml to ensure the measurement and temperature control effect.
When loading and unloading sample sleeves and rotors, be careful to avoid damage.
* When cleaning the sample sleeve and rotor, use a suitable solvent and ensure thorough drying.
The temperature setting must not exceed the range of -1 ° C to 150 ° C.
* Make sure that the sample sleeve is tightly connected to the temperature control part to ensure the temperature control accuracy.
When using DV-T2 software, ensure that the computer and instrument are connected correctly through the RS232 interface.
* The instrument should be placed on a stable working table to avoid vibration interference measurement.
Regularly check components such as the bearing system to ensure that the instrument is in good working condition.
