The Elcometer 456 Coating Thickness Gauge sets new standards; providing reliable and accurate coating thickness measurements; helping you to become more efficient.

The Elcometer 456 dry film thickness gauge is available in three different models. Each coating thickness gauge provides the user with increasing functionality - from the entry level Elcometer 456 Model B, to the top of the range Elcometer 456 Model T.

Integral coating thickness gauges are ideal for single handed operation as the wide footprint of the Bigfoot™ internal probe provides greater stability during coating thickness measurement - allowing for consistent, repeatable and accurate dry film thickness results.

Separate coating thickness gauge models, with their wide range of probes, provide even greater dry film thickness measurement flexibility.
Compatible with ElcoMaster® software and ElcoMaster® Mobile App, individual coating thickness measurements can be transferred via USB or Bluetooth® to PC or a mobile device for analysis and instant report generation.
