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 DeFelsko is 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 DeFelsko 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 DeFelsko?

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.
