Check Fluid Resistivity
Graco Part No. 722886 Resistance Meter and 722860
Probe are available as accessories to check that the
resistivity of the fluid being sprayed meets the require-
ments of an electrostatic air spray system.
Follow the instructions included with the meter and
probe. Readings of 25 megohms-cm and above provide
the best electrostatic results.
Check Fluid Viscosity
To check fluid viscosity you will need:
• a viscosity cup
• a stopwatch.
1. Completely submerge the viscosity cup in the fluid.
Lift the cup out quickly, starting the stopwatch as
soon as the cup is completely removed.
2. Watch the stream of fluid coming from the bottom of
the cup. As soon as there is a break in the stream,
shut off the stopwatch.
3. Record the fluid type, elapsed time, and size of the
viscosity cup.
4. If the viscosity is too high or too low, contact the
material supplier. Adjust as necessary.
WARNING
Fire, Explosion, and Electric Shock Hazard
Check the fluid resistivity in a non-hazard-
ous area only. Resistance Meter 722886
and Probe 722860 are not approved for use
in a hazardous area.
Failure to follow this warning could cause
fire, explosion, or electric shock and result
in serious injury and property damage.
