Equipped with a rugged Advanced body, the FNDS3 model features a 2.8-inch impact-resistant color touchscreen, fast measurement modes, and storage for up to 250,000 readings. The instrument is ready to measure, IP65 rated, and includes built-in calibration tools—delivering reliable performance even under harsh field conditions.

DeFelsko Digital Multi Thickness Gauge PosiTector 6000 FNDS3

This multi-thickness gauge combines versatility and precision. With duplex mode, real-time statistics, Hi-RES resolution, and wide international standard compliance (ISO, ASTM, SSPC etc.), the PosiTector 6000 FNDS3 supports both routine checks and demanding inspection protocols. Its ergonomic, portable design makes it practical for shop, field, or remote work.

Features

01
Duplex Mode (Paint + Zinc Thickness)

In one reading, the FNDS3 probe measures the combined paint/zinc layer over ferrous substrate (magnetic method) and paint over zinc (eddy-current method), then computes the zinc layer by subtraction—efficient for duplex systems.

02
High Accuracy over Range 0-1500 µm (0-60 mils)

Coating range covers up to ~1.5 mm or 60 mils, with tight accuracy tolerances (e.g. ± (0.05 mil +1%) for thin paint layers). Great for both thin and moderately thick coatings.

03
Large Display & Fast Measuring Speeds

2.8″ impact-resistant color touchscreen plus redesigned keypad; FAST mode allows 90+ readings/minute, Advanced scan modes up to 180+ readings/min. Speeds up inspections significantly.

04
Rugged, Field-Friendly Construction

IP65 enclosure; wear-resistant probe tip; rubberized grip and holster; operates on 3 AAA batteries with long battery life. Built for durability in rough environments.

05
Extensive Data & Standards Compliance

Stores large number of readings (250,000 in up to 1,000 batches for Advanced version); supports real-time statistics (average, min/max, stdev); includes long-form calibration traceable to NIST/PTB; conforms to many international standards (ISO, ASTM, SSPC, etc.).
