Style Name:NDJ-1 NDJ-1 Rotary ViscometerDigital Display Viscosity Meter Fluidimeter 220VHow To Use:1. Prepare the liquid and put it into a glass beaker or a right angle container with the diameter not smaller than 70 mm, height not smaller than 130mm, look after the liquid temperature2. Mount the protection bracket on instrument, turning right for mounting, turning left for removing3. Screw the selected rotor into connecting rod, turning right for mounting, turning left for removing4. When the reading data is too high or too low, the rotor or the rate can be changed, make sure the reading is between 20 and 805. Set range, coefficient, rotor and rate:5.1 Estimate approximately the viscose range, then select the rotor and the velocity based on the range table given below:For example, the viscosity of liquid is about 3000 mPa·s the settings should be as following:rotor 2 # with velocity of 6 rpm,rotor 3 # with velocity 0f 30 rpm5.2 If the viscosity of liquid can not be estimated, it should take a high value for real measurement5.3 Coefficient: the reading must be multiplied the specific coefficient in the coefficient table in order to get the absolute viscosity.That is: η=k · αη=absolute viscositycoefficientα = reading ( deflection angle)Specification:Power supply: 220V±10% ; 50Hz±10%Model: NDJ-1Measurement range: 1 ~1×105mPa.sMeasurement accuracy: ±5% (Newton liquid)Package Content:1 X NDJ-1 Digital Rotary Viscometer1 X Rotors 1#, 2#, 3# and 4#1 X Protection Bracket1 X Bracket3 X Adjusting Screw1 X Operation Manual1 X License1 X Wrench
