Brief introduction: VM4000 series vibrating string viscosity/density meter based on the current international the most advanced in the field of viscosity measurement method for measuring the vibration of the string, can simultaneously measure the density and dynamic viscosity and kinematic viscosity of liquid, the high precision, fast measurement speed, less sample weight etc, and is suitable for all kinds of fluid, such as lubricating oil, frozen oil, coolant, refrigerant, all kinds of organic compounds, etc., especially suitable for volatile liquid and high pressure measurement. Features: 1. Based on the most advanced international viscosity measurement in the field of Vibrating strings (Vibrating Wire) measurement method; 2. At the same time measuring liquid viscosity and density; 3. Don't need in the process of measuring fluid flow; 4. Simple structure, less dosage of samples; 5. Suitable for low temperature, high pressure measurement conditions, the measurable temperature range 272 ~ 272 ℃, pressure can reach 1 GPa; 6. With high measurement precision, short measuring time, easy to seal, etc; 7. Measurable viscosity range is bigger, change the radius of the vibrating wire or material, can be measured 10-3 to 103 mPa, s within the scope of the viscosity. 8. Volatile liquid and is especially suitable for high pressure measurement. Technical parameters: Measuring range: the kinematic viscosity: 0.1 ~ 2500 was/s Dynamic viscosity: 0.1 ~ 100 mPa, s The accuracy of the quasi: plus or minus 2.0% After sex now: plus or minus 2.0% Pressure range: 15 mpa Pressure control: optional (0.1 ~ 15 mpa) Temperature range, the standard room temperature (optional temperature liquid environment module) Temperature measuring accuracy: plus or minus 0.01 ℃ Pressure measuring accuracy: plus or minus 0.1% Measuring time: 5 min Sample usage: 200 mL Data transfer: USB Operating system: doing/Windows 7 / Vista/XP / 2003 Power source: 220 v, 50 hz
