PosiTest DFT Ferrous and Combo Gauges

PosiTest DFT Ferrous and Combo Gauges

Measures Coatings on all Metals


The PosiTest DFT measures coatings on all metal substrates and comes in two models: ferrous and combination (ferrous & non-ferrous). It is an economical solution for those who have no need for the innovative features of the PosiTector 6000, but still retains the uncompromising quality of DeFelsko coating thickness and inspection instruments. Fast, repeatable measurements with 60+ readings per minute and is ready to measure with no adjustment required for most applications. Features zero or 1 point calibration adjustment for complex applications and a strong, wear-resistant, ruby-tipped probe. 

It is ideal for Powder Coaters, Paint Applicators and Contractors, Coating Inspectors, and Automotive Detailers, Refinishers and Inspectors.
