Box Contents; Using The Gauge - Elcometer 103 User Manual

1 OVERVIEW
The Elcometer 103 Blast Nozzle Gauge
has been designed to provide a quick
and easy measurement of the orifice
size of an abrasive blasting nozzle.
Proper use of this gauge can determine nozzle
orifice wear which can cause low nozzle pressure
and decreased efficiency in the performance of
the nozzle's venturi.
This wear results in decreased productivity, increased abrasive
consumption and improper surface profile.

3 USING THE GAUGE

1 Unscrew the cap from the gauge body.
2 Remove the wax pencil from inside the gauge body.
3 Rub the wax pencil along the rounded side of the gauge body.
 An area from 3/16" to 5/8" should be marked with grease pencil.
4 Replace the wax pencil and screw the cap back on to the gauge.
5 Depressurise the blast system and remove the nozzle from the
blast hose coupling.
6 Insert the gauge into the back (threaded side) of the blast nozzle.
7 Rotate the gauge against the liner of the nozzle.
8 Remove the gauge and record the orifice size (in inches) at the
point where the lines have scratched in the wax mark.
The nozzle should be replaced when the orifice is worn more than
1/16" larger than the original orifice size, as this is the point that
performance begins to dramatically decline.
