Description

Elcometer 456 - Separate Coating Thickness Gauge

Dry Film Thickness - Digital

The Elcometer 456 coating thickness gauge is available with a wide range of interchangeable probes; providing greater coating thickness measurement flexibility on metal substrates.

• Measure coatings up to 31mm (1,220mils) on  metal substrates
• Easy to read, user definable display with automatic screen brightness
• Ergonomic design,  ideal for continuous use
• Dust and waterproof rugged design equivalent to IP64
• Temperature stable measurements

Scan and Auto Repeat Modes

Using the Scan Probe in Scan Mode

• Using the Elcometer 456 in Scan Mode with the Scan Probe enables users to significantly reduce dry film thickness inspection times without affecting accuracy:
• Slide the 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 thickness and any user-defined limits.

Using the Scan Probe in Auto Repeat Mode

• When the Scan Probe is slid over the coated surface in Auto Repeat Mode*, a coating thickness reading is taken approximately every half a second. Each individual dry film thickness 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 dry film thickness inspection of large coated areas.

Scan Probes

• The Scan Probes further enhance the speed and accuracy of field based dry film coating thickness measurement:
• Featuring a highly durable ‘snap on’ replaceable probe cap
• A revolutionary design which allows users to take individual readings or rapidly scan large surface areas - without damaging the probe or coating
• Uses the Elcometer 456’s patented offset feature1, ensuring that any cap wear during use2 is incorporated within the calibration process - the gauge even informs the user when to replace the cap.
• Standard Scan Probe or larger Roller Bearing Scan Probe available
• Roller Bearing Scan Probe is ideal for large coated structures, abrasive coatings & pre-construction primers.

Counted Average and Fixed Batch Modes

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 individual gauge readings to be taken within a spot measurement, the gauge stores the average of the individual gauge readings into the memory.

Fixed Batch Sizes

• The Fixed Batch Size feature within the Elcometer 456 Model T allows users to define the maximum number of readings in each batch.
• Once 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 measurements 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 requirements.  Each batch defines an area of measurement.
• When the 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.
