EXAMPLE OF MATERIALS NEEDED

FOR CALIBRATION OF A 

  

DIP-TYPE VISCOSITY CUP

*These are nominal values. For the actual centistoke value of the standard, refer to the value on the bottle label.
**NOTE: The 8mm ISO Cup is not available in the Dip version.

A.

One GARDCO Dip-Type Viscosity Cup

B.

The Conversion Grid sheet (for cup chosen) to convert seconds effl ux time (to nearest tenth of a

second) to centistoke viscosity. Every Gardco Cup is furnished with such a data sheet.

C.

One pint of certifi ed calibration oil (appropriate to cup chosen, see chart below)

D.

To insure highest accuracy of calibration, we recommend the use of ASTM mercury fi lled glass

type thermometers having an accuracy of 0.1°C (0.2°F). Use any of the following:

1.

Gardco Cat. No. VI-3130 glass mercury fi lled thermometer, 4-1/2" length, 20-30°C.
range.

2.

Gardco Cat. No. TH-02232 °C ASTM mercury fi lled glass thermometer, 10.8" length,
19-27°C. 

range.

3.

Gardco Cat. No. TH-02233 °F ASTM mercury fi lled glass thermometer, 10.8" length,
66-80°F. 

range.

E.

Container: 600 ml capacity glass beaker LA-2029060. LA-2029100 1000 ml glass beaker is

recommended for the Fisher Dip Cup.

F.

Gardco Cat. No. TM-AX705 digital electronic stopwatch, 0.01 second.

G.
