  • 【Rugged Construction】: Crafted from a treated aluminum cup, it has a capacity of 100 ± 1 ml. The bottom features a small hole with a diameter of 4 or 6 mm + 0.02 mm. The nozzle is made of stainless steel and has a polished interior to ensure smooth liquid flow
  • 【Measurement Principle】: The flow characteristics of a liquid are measured by measuring the time (in seconds) it takes for a specific volume (100 ml) of liquid to completely flow out of the hole at the bottom of the cup. A longer time indicates slower flow
  • 【Portable Design】: The lightweight and portable cup design allows for quick use in various locations. The fixed 100 ml capacity and 4 or 6 mm hole ensure consistent measurement conditions and reliable results
  • 【Simple Operation】: Fill the cup with the sample to be tested, allowing the liquid to flow naturally from the standard hole at the bottom. The measurement result is measured from the start of flow to the complete emptying of the cup, with the measured seconds being the measurement result
  • 【Versatile Application】: Suitable for measuring the flow time of liquids such as inks, coatings, and paints. Designed for liquids with flow characteristics ranging from 100 to 500, it meets the needs of common industrial scenarios

  • 【Ingenious Design】The viscometer is equipped with 4 rotors for different viscosity scopes of samples. It features with premium lifting system and angle adjustment for less errores. You can adjust the knobs to get suitable height and position.
  • 【Rotation Rate Of Rotors】 According to the viscosity range of different test liquids, different rotors (1,2,3,4) can be selected and different speeds (60,30,12,6) can be set. The knob adjustment is straightforward with a coefficient table on the top for easy reference. You can unlock a more unknown liquid viscosity.
  • 【± 5% Accuracy】 The viscometer uses a measuring disc, and the viscosity values are measured by moving the rotor rotation through the spindle and spindle, has a large viscosity measurement range of 10-100,000 cps and the measurement error: ± 5%, give your determination enough to better control my processes.
  • 【Motor Driven】The machine adopts a stepper motor driven by high subdivision, and the top of the machine is equipped with a standard horizontal air bubble, which has high sensitivity measurement and perfect data acquisition, so the test result is accurate and reliable.
  • 【Application】 NDJ-1 is commonly used to determine and measure liquid viscosity in many applications such as grease, painting, plastics, pharmaceuticals, and adhesives. There are no restrictions on the liquid, just put the rotor in the liquid and test it. But the liquid you measure should NOT exceed 80 ℃.
