Elcometer 456 Model E - 20 Probe Technical Specifications

20 PROBE TECHNICAL SPECIFICATIONS (EBST)
Available in a number of designs and scale ranges, all probes are supplied with an
Elcometer test certificate and a set of calibration foils appropriate to the scale range.
Ferrous probes measure non magnetic coatings on ferro-magnetic substrates. Non-
ferrous probes measure non conductive coatings on non-ferrous metal substrates. Dual
FNF probes measure both ferrous and non-ferrous applications with automatic substrate
detection.
