PosiTector SPG

Does the $\text{PosiTector}$ $\text{SPG}$ $\text{measure}$ $\text{pit}$ $\text{depth}$?

No. The $\text{PosiTector}$ $\text{SPG}$ is explicitly designed as a $\text{surface}$ $\text{profile}$ $\text{gage}$ to measure the $\text{peak}$–$\text{to}$–$\text{valley}$ $\text{height}$ of an $\text{anchor}$ $\text{pattern}$ on a blasted surface, not the generalized depth of isolated $\text{corrosion}$ $\text{pits}$.

Can the $\text{SPG}$ $\text{be}$ $\text{used}$ $\text{on}$ $\text{non}$–$\text{metallic}$ $\text{substrates}$?

Yes. While often used for steel, specialized models like the $\text{PosiTector}$ $\text{SPG}$ $\text{CS}$ $\text{(Textured}$ $\text{Coatings)}$ $\text{and}$ $\text{SPG}$ $\text{TS}$ $\text{(Concrete)}$ offer extended measuring ranges and larger probe tips suitable for high-profile non-metallic surfaces.

Is $\text{the}$ $\text{probe}$ $\text{tip}$ $\text{replaceable}$ $\text{in}$ $\text{the}$ $\text{field}$?

Yes. The durable $\text{tungsten}$ $\text{carbide}$ $\text{tip}$ is $\text{field}$–$\text{replaceable}$, which is a major advantage for continuous operation. The standard 60∘ $\text{tip}$ is most common, but 30∘ tips are also available to comply with standards like $\text{AS}$ $\text{3894.5}$–$\text{C}$.

How $\text{is}$ $\text{the}$ $\text{PosiTector}$ $\text{SPG}$ $\text{calibrated}$ $\text{and}$ $\text{verified}$?

The gage is factory-calibrated and includes a $\text{Long}$ $\text{Form}$ $\text{Certificate}$ $\text{of}$ $\text{Calibration}$ traceable to $\text{NIST}$ $\text{or}$ $\text{PTB}$. Daily operational accuracy can be verified using the supplied $\text{glass}$ $\text{zero}$ $\text{plate}$ $\text{and}$ $\text{metal}$ $\text{check}$ $\text{shim}$.

Is $\text{the}$ $\text{PosiTector}$ $\text{SPG}$ $\text{suitable}$ $\text{for}$ $\text{round}$ $\text{surfaces}$ $\text{like}$ $\text{pipes}$?

The $\text{PosiTector}$ $\text{SPG}$ $\text{OS}$ model is specifically designed for $\text{curved}$ $\text{or}$ $\text{convex}$ $\text{surfaces}$. It features an $\text{integral}$ $\text{V}$–$\text{groove}$ and a $\text{self}$–$\text{leveling}$ $\text{probe}$ foot to ensure proper alignment and perpendicularity on surfaces with an $\text{OD}$ $\text{above}$ $\text{3}$ $\text{mm}$.
