F.A.Q.

plus-icon
minus-icon

Is the PosiTector SPG TS traceable to PTB or NIST?

All PosiTector SPG probes including the PosiTector SPG TS are traceable to PTB.

plus-icon
minus-icon

Is the PosiTector SPG calibrated at the factory?

The PosiTector SPG arrives fully calibrated and ready to measure. A Long-Form Certificate of Calibration traceable to NIST or PTB is included, which documents actual readings taken by your instrument at our calibration laboratory on standards traceable to a national metrology institute. Beware of ‘Certificates’ or ‘Certificates of Conformance’ offered by competitors. These typically do not include actual instrument readings, and are often insufficient to meet common quality requirements.

Gage accuracy and correct operation can be verified using the included metal shim and glass zero plate.

plus-icon
minus-icon

Can I measure curved surfaces with the PosiTector SPG?

Yes. The PosiTector SPG OS is ideal for measuring the peak-to-valley surface profile height of convex abrasive blast cleaned surfaces such as pipes and tanks.

The PosiTector SPG OS probe features an integral V-groove and optional Large V-groove Adaptor to assist with proper probe positioning on cylindrical parts. Simply align the V-groove along the axis of the curved surface using the notches on the probe face and/or the indicator arrows on the face of the adaptor.

plus-icon
minus-icon

Can the PosiTector SPG be used on non-metallic substrates?

Yes! While primarily used to measure blasted steel, the PosiTector SPG can be used for many applications. The PosiTector SPG TS and PosiTector SPG CS also feature an extended range and larger radius probe tip to suit a wide range of applications:

  • The PosiTector SPG CS will quickly and accurately measure the surface profile of textured coatings.
  • The PosiTector SPG TS will quickly and accurately measure the surface profile of concrete.
plus-icon
minus-icon

Why are there 30˚ and 60˚ tips for the PosiTector SPG?

The PosiTector SPG uses a durable tungsten carbide tip for long life and continuous accuracy. If required, SPG probe tips can be replaced by the gage operator.

  • The 60° tip complies with most test standards including ASTM D 4417 B.
  • 30° tips are available for conformance to Australian standard AS 3994.5-C.
plus-icon
minus-icon

Can the PosiTector SPG be moved over the surface to provide a ‘scan’?

No. The PosiTector SPG is a surface profile gage which utilizes a depth-micrometer to quickly and accurately measure and record peak-to-valley surface profile heights on blasted steel, textured coatings, and concrete.

Like other instruments of this type, the PosiTector SPG is not dragged across a surface: the gage operator takes an individual reading in one location on a surface, lifts and places the gage on another location on the surface for another individual reading, and so on.

The PosiTector SPG comes complete with statistics mode and internal memory, allowing you to average a series of readings.

plus-icon
minus-icon

Does the PosiTector SPG measure pit depth?

No. Pit gages are a general category of instruments used to measure pits and other surface variations. The PosiTector SPG is specifically designed to measure and record peak-to-valley surface profile heights on a blasted steel surface.

plus-icon
minus-icon

Should I purchase the PosiTector RTR Replica Tape Reader or PosiTector SPG Surface Profile Gage for my application?

Both instruments conform to ASTM D4417 "Standard Test Methods for Field Measurement of Surface Profile of Blast Cleaned Steel".

The PosiTector SPG conforms to Method B of ASTM D4417. The PosiTector SPG measures quickly, and has no per-test cost. It keeps a digital record of each measurement, is less operator dependent, as no burnishing of replica tape is required. It also has a greater range than replica tape.

The PosiTector RTR conforms to Method C of ASTM D4417. It is used together with Testex Replica Tape, a widely used and respected method to measure surface profile. It has the ability to measure on curved surfaces, and gives the user the option to retain the replica tape; a physical replica of the tested surface.

plus-icon
minus-icon

How often should the PosiTector probe be recalibrated?

PosiTector probes include a Certificate of Calibration showing traceability to NIST or PTB included (Long Form) with each probe—with no expiry or end date. They have no shelf life, therefore the length of time in the field is not a good indicator for recalibration intervals. Many organizations with quality programs and recertification programs require annual recalibrations, and this is a good starting point for most users. DeFelsko recommends that customers establish calibration intervals based upon their own experience and work environment. Based on our product knowledge, data and customer feedback, a one year calibration interval from the date the instrument was placed in service is a good starting point.

plus-icon
minus-icon

Why does the finger grip sleeve on the PosiTector SPG OS feel loose?

The PosiTector SPG OS is designed with a self-leveling probe foot to ensure perpendicularity to the part being measured. The finger grip sleeve needs to have a loose fit in order for self-leveling to work.

plus-icon
minus-icon

What is the benefit of the optional Large V-groove Adaptor?

The Large V-groove Adaptor offers enhanced stability on 30 45 cm (12 18") OD pipes and helps with proper positioning and measuring technique. The adaptor should not be used on pipes greater than 46 cm (18”).

plus-icon
minus-icon

Can I compare readings from a PosiTector SPG OS with readings from a PosiTector SPG or SPG S?

On flat surfaces, the PosiTector SPG, SPG S, and SPG OS probes will measure similarly. However, measurements taken by the PosiTector SPG OS (or any depth micrometer surface profile instrument) on rounded surfaces should only be compared with measurements taken on surfaces with a similar radius. On flat surfaces, the probe foot contacts the substrate over its entire area, while on curved surfaces the probe foot contacts an increasingly smaller area as the radius decreases. This may cause a slight decrease in the reported peak-to-valley surface profile height, since the probe foot sits on fewer peaks as the contact area decreases.

plus-icon
minus-icon

Do your instruments require any formal training for use? Do you offer ‘demo’ models?

No. Our surface profile instruments are designed for simple operation, feature easy-to-use menus, instruction manuals, and helpful videos. In lieu of demonstration models, we provide unlimited technical support via telephone and/or email, and a limited 30-day money back guarantee.
