Product Specification

GM280F Film/Coating Thickness Gauge Introduction
This product adopts piezoelectric effect of artificial polarized ceramic for design. it is suitable for monitoring of all kinds of vibrating mechanical facility, specially the vibration measurement of rotating and reciprocating machinery. The unit can measure acceleration, velocity and displacement, which is widely used in mechanical manufacture, electric power metallurgy and general aviation etc. Field.

GM280F Film/Coating Thickness Gauge Features
• LCD displays measurement result and conditions directly
• Measures acceleration (m/s² peak), velocity (mm/s ms), and displacement (mm p-p)
• Selective vibration characteristic
• Uses hi-sense of vibration sensor, measuring accurately
• Equipped with two probes (S and L) to adapt the different measurement requirements
• Provides a magnetic probe to fit the condition uneasy hold on by hand
• Low battery indication
• Auto turn off function
• LCD back light function
• Maximum value hold function
• Temperature unit °C/°F selection
