1.0 Introduction:

BGD 151 Rotary Viscometer is used in measuring viscosity friction and absolute viscosity of liquid. It

has four rotors of NO.1-4 and can be chosen to use in accord with viscosity of the liquid to be determined

rotation speed. It is widely used to determined viscosity of various liquid such as oil, paint, plastic, food

medicine, adhesive, etc. It is widely applied in the field of petro chemistry , medicine, food, light industry,

textile industry, scientific research, etc.

2.0 Main Technical Parameters:

◆ Range of Measurement of Viscosity: 10-100,000mpa.s(cP)

◆ Rotors to be used to measure: four rotors of NO.1-4

◆ Rotate speed: 6r/min¡,12r/min,30r/min,60r/min

◆ Meter-age error ±5%(Newtonian fluids)

◆ Electrical power: 220V/50Hz

◆ Weight: 7.9Kg

◆ Dimensions: 410×350×440mm(L×W×H)

3.0 Test Environment:

3.1 When installing the viscometer, locate the instrument on a sturdy bench apart from environment of

strong draught ﹑ strong magnetic field ﹑ strong electrical field ﹑ strong electromagnetic pulse

disturbance.

3.2 Be sure that it is safer for an operator, attach the power cord to the appropriate power source

(grounded outlet).

3.3 Testing Environment: 23℃±2℃, relative humidity should not be over 75%.

3.4 Sample temperature should be 23℃±2℃.

4.0 Operation and Usage:

4.1 Take the instrument out from the box, put it on the worktable.

4.2 Adjust the two bolts(in the bottom base of machine) till the machine is level(the bubble is in the

middle of the circle)

4.3 Attach the power cord to the appropriate power source

4.4 Pour the sample into the container and stir it uniformly(the diameter of container is not less than

70mm).Control the temperature of the liquid accurately.

4.5 Install the protection shelf on the viscometer(revolve towards right is installing and towards left is

unloading )

4.6 Install the selected spindle on the connecting screw(revolve towards left is tighten and towards right

is loose )

4.7 Whirl the rise-fall knob and make the machine fall slowly. The spindle is immerged till its sign is level

with the surface of tested liquid .

4.8 Turn on the viscometer power switch which is on the side of viscometer and the spindle begin to

whirl in the liquid. After 20-30 seconds or the finger is steady ,read the value of finger.

Note: If the speed of whirl is too fast to read the value of finger, you can put down the

controlling pole and turn off the power switch.

4.9 It is better that containing the value of finger is between 30 to 90.
