Defelsko The positector SPG Surface Roughness Gauge, model number Standard SPG1-E, is the standard model of the SPG series and is a built-in stylus typeSurface profile roughness measuring instrument.Standard SPG1-EThe roughness gauge is designed to test sandblasted steel, to measure and record the surface profile roughness,SPG1Roughness measuring instrumentThe thickness range of measurement is 0~500 microns.




Complies with standards ASTM D4417-B, SSPC-PA17, AS 3894.5-C (with optional 30° tip angle), U.S. Navy NSI 009-32, SANS 5772, etc
1) Simple
With a fast measurement speed of more than 50 readings per minute, it is suitable for fast and accurate measurement of the surface roughness of large, flat surface areas
Enhanced one-handed menu navigation
The reset function enables an immediate factory reset
2) Durable
Alumina wear surface and tungsten carbide stylus tip for long life and continuous accuracy – field replaceable
Resistant to solvents, acids, oils, water and dust – weather-resistant
Rugged, outdoor/indoor instrument - excellent for use in the field or factory
Shock-absorbing rubber protective holster, belt clip and wrist strap
The main unit and probe are guaranteed for two years
3) Precise
Built-in temperature compensation ensures accurate measurements
The calibration certificate is traceable to the PTB
