Mode Scan
When the Scan Mode* is selected users can slide the Ultra/Scan probe over the entire surface area. As the probe is lifted off the surface the gauge displays the average coating thickness value, the highest thickness and the lowest thickness values. Each set of three readings (average, high and low) can be displayed on the run graph and stored into the memory.

During each scan the Elcometer 456 displays the live thickness reading together with an analogue bar graph which graphically indicates the thickness relative to both the nominal tickness and any user-defined limits.

* Scan and Auto Repeat Modes require an Elcometer 456 Model T gauge with Ultra/Scan Probe.
Coating Thickness Gauge - Scan


Auto Repeat Mode
When the Ultra/Scan Probe is slid over the coated surface in Auto Repeat Mode*, a reading is taken approximately every half a second. Each individual reading is stored into the memory.

With a reading rate in excess of 140 readings per minute the Auto Repeat Mode can significantly speed up the inspection of large coated areas.

* Scan and Auto Repeat Modes require an Elcometer 456 Model T gauge with Ultra/Scan Probe.
Coating Thickness Gauge - Auto repeat


Ultra/Scan Probe
Featuring a highly durable ‘snap on’ replaceable probe cap, the Elcometer 456 Ultra/Scan Probe is a revolutionary design which allows users to take individual readings or rapidly scan large surface areas - without damaging the probe or the coating.

When used in conjunction with the Elcometer 456 Scan or Auto Repeat Modes* the Ultra/Scan Probe enables users to significantly reduce inspection times without affecting accuracy.

The Ultra/Scan Probe uses the Elcometer 456’s patented offset feature**, ensuring that any cap wear during use*** is incorporated within the calibration process. The gauge even informs the user when to replace the cap.

** Patent Number US6243661
*** When tested on smooth surfaces probe end caps have been scanned in excess of 50km (30 miles).


Counted Average Mode
The Elcometer 456 Model S and Model T are supplied with the Counted Average Mode. Once the user has defined the number of induvidual gauge readings to be taken within a spot measurement, the gauge stores the average of the individual gauge readings into the memory. Coating Thickness Gauge - Counted average
Counted Average and Fixed Batch Sizes
can be used with all Elcometer 456 probes


Fixed Batch Sizes
The Fixed Batch Size feature within the Elcometer 456 Model T allows users to define the maximum number of reading in each batch. On ce the maximum number of readings has been reached the gauge automatically opens up a new
batch which is linked to the previous batch (name-1, name-2, etc.).


Working with Standards and Test Methods
International Standards and test methods often describe the number of individual gauge readings
to be taken in a spot measurement and/or the number of spot measurements required over a defined surface area.

SSPC PA2 requires a minimum of three gauge readings to be taken per spot measurement and five spot measurement over 10m2 (~100ft2).

The Elcometer 456 Model S or Model T can be set with a counted average of three and a fixed batch size of five to meet these requierements. Each batch defines an area of measurement.

When the Ultra/Scan Probe is connected to the Elcometer 456 Model T with Auto Repeat Mode
selected, SSPC PA2 (or similar test methods) can be completed more than 40% faster.

Integral & Separate model range
Coating Thickness Gauge The Elcometer 456 is available in four different models. Each gauge provides the user with increasing functionality - from the entry level Elcometer 456 Model E, to the top of the range Elcometer 456 Model T.

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

Separate models, with their wide range of probes, provide even greater measurement flexibility.

Probe Range
All Elcometer 456 probes are fully interchangeable and are available in a number of design and scale ranges to meet your specific application.
Straight Probes Waterproof Probes
Measures coating on both fiat and curved surfaces Sealed for use underwater at depth, even in diving gloves
Mini Probes High Temperature Probes
Ideal for measuring coatings on edges, narrow pipes or small surface areas For use on hot coated materials up to 250°C (480°F)
Right Angle Probes Anodiser Probes
For taking readings where access is restricted Chemical resistant washable probes - ideal for the anodising environment
PINIP™ Probes Armoured Probes
Plug-in probes convert a separate gauge into an integral gauge Probes with metal reinforced heavy duty cables, reducing the risk of cable damage
Telescopic Probes Soft Coating Probes
Extending right angle probes for out of reach areas Large surface area probes for soft reach materials
(HVCA approved)
Ultra/Scan Probes Specialist Probes
These probes are fitted with replaceceable probe caps - allowing users to take individual readings or scan large surface areas without damaging the probe These probes are designed for measuring on specialist substrates, such as graphite, or electroplated components
Ferrous probes measure non magnetic coatings on ferro-magnetic substrates. Elcometer 456 ferrous gauges accept any ferrous probe. Non-ferrous probes measure non conductive coatings on non-ferrous metal substrates and Elcometer 456 non-ferrous gauges accept any non-ferrous probe. Dual FNF probes measure both ferrous and non-ferrous applications with automatic substrate detection. Elcometer 456 FNF gauges accept all ferrous, non-ferrous and dual FNF probes.

Elcometer probes have a maximum operating temperature of 80°C (176°F) with the exception of separate ferrous probes 150°C (300°F) and Hi-Temperature PINIP’s 250°C (480°F). The stated temperature is the substrate temperature, and the duty cycle of the probe must be reduced to ensure a minimal temperature build-up within the probe.

Sauf mention contraire, les sondes séparées Elcometer fonctionnent à une température maximum de 150°C (300°F), les sondes PINIP™ fonctionnent à une température maximum de 80°C (176°F).

Toutes les sondes Elcometer sont livrées avec un certificat de test et un jeu de feuilles d’épaisseur adapté à la plage de mesure de la sonde - voir p
