Feature(may vary by option.)
●◆This device is mainly used to measure the dynamic viscosity of a fluid coating close to Newton fluid or Newton fluid, and can also be used according to the need to compare the measurement values.
●◆Correction coefficient: K value is the time after filling secondary standard oil with the temperature condition (20°C±0.1°C), flow time must be within 150 seconds and the K value should be within 1±0.03. Viscosity meter must be calibrated regularly within the frequency of use.
●◆ Place the viscosity cup in a horizontal bubble measuring coupling, adjust the horizontal screw on the base to match the bubble center. The capacity of the receiver cup is about 150ml, which is used for measuring liquid.
●◆Viscosity TND-4T viscosity meter is the viscosity of the condition, which means a certain amount of sample at temperature, and the viscosity of the set opening holes in seconds with time.

Description
The viscosity measured by the TNT-4T viscosity meter is a conditional viscosity that shows the time of a certain amount of sample running out of the hole in the specified opening in seconds. Convert the spill time (s) of the obtained sample to a dynamic viscosity value (mm²/s) by following forms:
t<23 s, t=0.514μ+11
23 s≦t≦150 s, t=0.23μ+6.0
During formula: t--spill time, s; μ--exercise viscosity, mm²/s
