JUNG CHECK
Falling Ball Viscosity Measuring Device
Features:
Benefits:
The viscosity meter consists of a metal tube, in which the liquid under inspection is filled. Both sides of the test tube get closed with transparent disks. Inside the tube a ball "falls" through the liquid upon inverting. The falling-time of the ball stands in direct relation to the viscosity of the liquid.
You read the actual temperature from the built-in thermometer, take the average falling time and calculate the viscosity at actual temperature according to the provided formula.
Total measuring range is covered by employing 3 different balls. Based on the falling time of one minute, measuring range for each ball divides in:
This corresponding falling time is based on a density of 0,9875 g/ml. and is applicable with common accuracy for fluids having a viscosity of more than 10 mm?/s at current measuring temperature. For different densities, please use the provided formula or contact your lube oil supplier who can provide you with a V-T diagram for the oil under inspection.
Features:
- measuring range: 10 - 999 mm?/s
- measuring time: about 5 min.
- accuracy: +/- 3 %
Benefits:
- quick determination of oil quality
- no consumable parts
- easy to use on site
- handy and time proven

Total measuring range is covered by employing 3 different balls. Based on the falling time of one minute, measuring range for each ball divides in:
| standard ball | (16,20 mm) | 60 cSt | (1s = 1,0cSt) |
| complementary ball | (15,87 mm) | 270 cSt | (1s = 4,5cSt) |
| complementary ball | (14,29 mm) | 4000 cSt | (1s = 65,0cSt) |
