Check Fluid Resistivity

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.
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:
•
•
1. Completely submerge the viscosity cup in the fluid.
2. Watch the stream of fluid coming from the bottom of
3. Record the fluid type, elapsed time, and size of the
4. If the viscosity is too high or too low, contact the
