Measuring Range: 0 - 40 mils / 0 - 1000 µm

The PosiTest DFT Coating Thickness Gage measures coatings on metal substrates. It is the economical choice that retains the uncompromising quality of PosiTest coating thickness and inspection instruments. Accurate and economical the DFT is the ideal instrument for Powder Coaters, Paint Applicators, Coating Inspectors... Easy-to-read oversized LCD display is reversible for reading when inverted.

Two Models

  • DFT-Ferrous
    measures non-magnetic coatings on steel.
  • DFT-Combo
    measures both non-magnetic coatings on steel AND non-conductive coatings on aluminum, brass, etc. Automatically recognizes the substrate and takes a measurement.

Ideal for

  • Powder Coaters
  • Paint Applicators and Contractors
  • Coating Inspectors
  • Automotive Detailers, Refinishers and Inspectors


  • Includes Long Form Traceable Calibration Certificate
  • Fast, repeatable measurements - 60+ readings per minute
  • Ready to measure - No adjustment required for most applications
  • Zero or 1 Point Calibration Adjustment for complex applications
  • Onscreen averaging for up to 99 readings
  • Strong, wear-resistant, ruby-tipped probe
  • V-groove in probe for positioning on cylindrical parts

FAQ's (Frequently Asked Questions)

When do I buy the PosiTest DFT instead of the PosiTector 6000?
The PosiTest DFT is a simple, economical solution for those who have no need for the innovative features of the PosiTector 6000 Standard or Advanced models including higher resolution and accuracy, internal memory, PosiSoft software compatibility and universal probe interchangeability. The PosiTector 6000 was designed for the harshest of environmental conditions. The impact resistant, high grade industrial strength housing is solvent, acid, oil, water and dust resistant. PosiTector 6000 Advanced models have additional features including increased memory storage, scan mode, SSPC PA2/PSPC-90/10 modes and WiFi wireless technology for connecting to mobile devices.

What does the PosiTest DFT offer that other low-cost gages don’t?
We’ve packaged PosiTector 6000 probe technology in a smaller, simpler, more economical platform. The PosiTest DFT is designed for users who don’t need memory or downloading features- just the quality probe technology that manufacturers are known for. Our reliable ruby-tipped probes are wear-resistant and measure accurately — both out-of-the-box and after extended use. There is no need for repeated calibration adjustments like with cheaper instruments. The PosiTest DFT is a simple gage that retains proven factory quality.

How can I make calibration adjustments with the PosiTest DFT?
For most applications, the PosiTest DFT is ready to measure right out of the box. When necessary, a Zero or 1 Point adjustment can be performed via the gage menu.

How is the PosiTest DFT calibrated at the manufacturer?
The PosiTest DFT is calibrated against known standards traceable to a National Metrology Lab. A long form Certificate of Calibration containing actual thickness measurements is included with every gage.

Can the PosiTest DFT store or print data?
No. The PosiTest DFT has a running average mode which provides the average for up to 99 measurements. The readings, however, are not stored in memory. Once the gage is powered off, the readings are erased. The PosiTest DFT cannot print readings.

How does the menu work?
The icon-based menu is easy to use. Simply press both the (-) and (+) buttons simultaneously to enter the menu. Press either button to move the cursor, and press both buttons to select an option.

Do your instruments require any formal training for use? Do you offer ‘demo’ models?
No. Our instruments are designed for simple operation, feature easy-to-use menus, both full and quick 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.

Is the PosiTest DFT calibrated at the factory?
The PosiTest DFT 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. ‍

Complete Kit

The DFT comes complete with built-in probe, wrist strap, plastic shims, Long Form Certificate of Calibration traceable to PTB, hard shell storage case, AAA battery, instructions, and two (2) year warranty.
