Monitoring the blasting process – enhancing safety and surface quality
During blasting, parameters such as pH, salt or chloride contamination, and the condition of the nozzle are critical for surface cleanliness and the adhesion of the subsequent coating.
Why control these parameters?
Contaminated media or worn nozzles lead to reduced cleaning quality, increased corrosion risk, and higher abrasive consumption – especially when media are recycled. Timely inspection prevents future coating failures.

- Elcometer 138 Abrasive Soluble Salt Test Kit – ASTM D4940 – determines salt concentrations in abrasive material or rinse water to avoid contamination. (elcometer.com)
- Elcometer 134A / 134W Test Kit – measures chloride levels in abrasive media or water to identify harmful chloride contamination. (elcometer.com)
- Elcometer 103 Blast Nozzle Gauge – measures the nozzle orifice diameter and detects wear that could reduce blasting performance. (elcometer.com)
- Elcometer 102 Needle Pressure Gauge – measures the actual nozzle pressure, which can be affected by worn nozzles or long hoses. (elcometer.com)
Practical tip:
Before each job, quickly check salt or chloride levels, measure nozzle diameter, and record pressure – this helps identify wear or contamination before they jeopardize coating performance.
