JVH-2 portable kinematic viscometer is designed to meet the rapid detection requirements of outdoor sites. It is easy to operate and integrates an efficient automatic cleaning and automatic drying system. It can quickly measure the kinematic viscosity of transparent and opaque Newtonian liquids, including new lubricating oil and in-use oil, at multiple temperatures.
A Portable Kinematic Viscometer is a compact, field-deployable instrument designed to measure the kinematic viscosity of liquids—typically petroleum products, lubricants, fuels, and hydraulic oils—directly at the sampling site.
Kinematic Viscometer Core Function
A portable kinematic viscometer measures:
Kinematic viscosity at 40°C
Kinematic viscosity at 100°C
Sometimes calculates Viscosity Index (VI) automatically
Real-time temperature compensation
These values are critical for evaluating oil condition and compliance with industry standards.
Kinematic Viscosity Meter Measurement Principles
Portable models typically use one of the following technologies:
A. Capillary (Ubbelohde/Cannon-Fenske Principle)
Measures flow time through a calibrated capillary tube
Follows gravitational flow principle
Based on standards like ASTM International ASTM D445
B. Microfluidic/Pressure Differential Method
Uses pressure sensors to calculate viscosity
Faster and more automated
C. Vibrational (Oscillating Piston or Tuning Fork)
Measures damping characteristics of a vibrating element in fluid
Compact and rapid-response
Less sensitive to operator handling
Why "Portable" Matters
Traditional laboratory viscometers require:
Constant-temperature oil baths
Glass capillaries
Lab environment
Skilled technician
Portable units enable:
On-site lubricant condition monitoring
Immediate decision-making
Reduced downtime
Oil change optimization
This is especially valuable in:
Power plants
Marine engines
Mining operations
Aviation maintenance
Oil & gas fields
