Elcometer 103 Blast Nozzle Gauge

The Elcometer 103 Blast Nozzle Gauge measures the orifice size of an abrasive blasting nozzle.

This gauge is used to determine the nozzle orifice wear which leads to low nozzle pressure and decreased efficiency in the performance of the nozzle's venturi. Nozzle orifice wear results in decreased productivity and increased abrasive media consumption.

To ensure your nozzle provides continuous high production, as a general rule, replace your nozzle when the orifice wears by 1 nozzle size.
