These robust, hand held instruments are used for measuring the thickness of materials where access to only one side of the test piece is available. Many different materials can be measured including steel, cast iron, plastic, epoxy resin and glass fibre, etc.

Specifications Elcometer 205-206-206DL :

• Hand held and robust
• Backlight display on all versions
• Data output available on the Elcometer 206 and 206DL. ElcoMaster™ and EDTS+ Excel Link software supplied free of charge with the Elcometer 206DL
• Memory capacity of 1000 readings on 206DL

Material Thickness

The thickness of materials cannot always be determined by direct measurement as access to both sides is not always possible. The effects of corrosion and erosion at the back of a metal panel may reduce its thickness significantly yet not affect the front surface. Pipelines, for example, may appear corrosion free on the outside but can be eroded by the flow of material on the inside. Machined or cast items may have thin walls that cannot be determined by calipers or other non-destructive tests. Three calibration options – Single Point Calibration, Two Point Calibration, Speed of Sound

At a glance:

• Simple to use robust, rugged thickness gauges to measure material thickness.
• Wide range of probes to choose including high temperature transducers.
• Gauges range from a low cost basic version to full statistics and memory.

The Elcometer Ultrasonic Thickness Gauge Features Explained:

• Interface-to-Echo Mode : In interface-to-echo mode, the gauge can take readings on thicker plastics and other materials between 1.65mm and 25.4mm (0.065" to 1")
• Echo-to-Echo Mode: Measurements can be taken on materials as thin as 0.15mm (0.006 inches). In echo-to-echo mode, the user can take measurements on pre-coated materials without having to remove the coating prior to measurement i.e. the gauge ignores the coating thickness.
• High Speed Scan Mode: Identifies the minimum thickness point over a large area by moving the transducer over the surface. While the transducer is in contact with the material being measured the smallest value is held in memory and displayed when scanning is complete.
• PLAS Mode: Specifically for use when measuring thin plastics. Please note that to use this mode, a special Graphite Delay Line must be purchased, Part Number T92016871.
• Differential Mode: Displays the positive or negative difference between a pre-set nominal (target) thickness value and the actual measured value.
• Alarm Mode: Allows the user to set a target so that an audible and visual alarm operates when taking measurements. If the measurement falls below a pre-set nominal (target) value a red LED will light and the bleeper sounds. A green LED will light to indicate an acceptable thickness.
• Data Output: Allows the user to send data direct to a printer or PC.
• Data-Logging: A storage capacity of 1000 measurements – 10 files consisting of 100 sequential storage locations. Allows the user to send data direct to a printer or PC.
• EDTS⁺ Excel link Software: PC data transfer utility including generator of ASCII files and “data drop” add in for Microsoft Excel™ spreadsheets.
• ElcoMaster™ Software: Stand alone data management program with advance facilities for archiving, reporting, analysis and data export.
