• Complete range of standard and “thin substrate” actuator skirts (compatible with F506) for controlling coatings applied to thick, thin, flat or convex substrates
• Store up to 60,000 records with individual pull graphs for up to 2,500 alpha-numeric batches, including attribute failure mode information.
• USB and Bluetooth® data output - Compatible with ElcoMaster™ App for iPhone, iPod, iPad and Android mobiles.

Explanation of main features

Left image: Automatic adhesion tester with selectable tensile scales for 10, 14.2, 20 and 50 mm diameter studs. Image center : Displays measurement graphics or live measurement, as well as adhesion value. Right image: Each traction scale graph is user-definable, and can be saved with each reading.

Left image: Storage of individual measurements and tensile scale graphs in up to 2,500 alpha-numeric batches, with date, time and attribute information. Image in center : Possibility of applying traction up to the maximum or a predefined limit. The time limit function allows users to define a delay before the pressure returns to zero. Right image: Recording of cohesive and adhesive failure attributes, as well as your bond strength data, in compliance with national and international standards.

Left image: Operates on standard rechargeable batteries or mains power*. Each battery charge performs up to 200 pulls. Battery recharge time is less than 300 minutes. Image center: Data transfer to your PC via USB or Bluetooth® for further analysis with ElcoMaster™ software or view live graphs of the tensile curve in ElcoMaster™ during the test. Right image : Wireless use with Bluetooth® communication to link the gauge to an Android™ or iPhoneǂ mobile. GPS coordinates from your cell phone can be added to reports and sent instantly by email.

Left image: The range of collars for standard and thin substrates allows each gauge to be used with reusable studs of 10, 14.2, 20 or 50 mm diameter; ideal for testing coatings on thick, thin, flat or convex substrates. Center image: The optional magnetic fixing anchor prevents the actuator from falling out during tests on vertical surfaces or when testing at height. Right image: Supplied in a sturdy plastic case for easy transport and use at the inspection site. * T model only. ǂ iPod, iPhone and iPad compatible  

Evaluation of results - Break attributes

Many national and international standards, including ISO 4624 and ASTM D4541, require the user to record not only the pull-out force, but also the nature of the break. This is done by examining the face of the stud and assessing the cause of failure. In “Advanced” mode on the F510, it is possible to select the “Attribute” function (Menu Mode / Configuration / Gauge / Advanced), enabling the nature of the fracture to be recorded and stored in memory for each reading.

Stud examination a) Cohesive failure: The coating breaks within a coating layer, leaving the same amount of coating on the surface and on the stud face. b) Adhesive failure: Failure occurs at the interface between the layers (intra-coating). The amount of “coating” on the stud face will not be the same as on the test area. c) Adhesive failure: If there is no coating on the pad, the failure should be recorded as an adhesive failure. This may be due to incorrect or insufficient mixing of adhesive components, or incompatibility between surface, adhesive, liner and test area.

This data is stored in the batch and can be consulted at any time: ##.## MPae N% A M% A/B, where; ##.## MPae = Tensile force in MPa or other unit of measurement (psi, Newton or Nmm-2)

• N% = Percentage of cohesive failure(f)
• A = Cohesive failure layer
• M% = Percentage of adhesive failure(f)
• A/B = Intra-coating adhesive failure

(d) The number of layers can be set by the user in the Batch / New Batch / Number of Layers menu. This affects the number of available layers selectable during attribute registration. The maximum number is five layers, excluding substrate and glue. (e) Or equivalent units. (f) Tolerance of 10%, in accordance with international standards.
