Foundrax launches portable automatic Brinell microscope

Foundrax has launched a self-contained microscope for automated Brinell testing. BRINtronic-RIVO integrates imaging, processing, illumination, and touchscreen control in a sub-1kg unit designed for production and field quality checks.


Foundrax Engineering Products has launched the BRINtronic-RIVO, a self-contained automatic Brinell microscope that integrates imaging, illumination, processing, and display hardware into a portable unit weighing less than 1kg.

The new instrument removes the separate PC, control box, and cable used by earlier portable arrangements. An operator places the microscope over a Brinell indentation, starts the measurement, and receives a hardness result on the integrated touchscreen in about a second. Foundrax says the internal battery is designed to last a full shift under normal use.

RIVO measures the indentation across 800 diameters. ISO 6506 and ASTM E10 require Brinell indentations to be measured across two diameters, so the larger data set is intended to reduce the influence of local surface features and operator judgement on the result. The instrument also evaluates surface preparation and warns the user where an indentation is out of round beyond the limit defined by ASTM E10.

Those functions address a longstanding weakness in Brinell testing. The test itself uses a hard ball indenter under a specified load, with hardness calculated from the resulting indentation. Producing the indentation is mechanically straightforward; reliably establishing its diameter on an industrial surface can be less so, particularly where grinding marks, reflectivity, poor preparation, or human interpretation affect where the edge is judged to sit.

Automatic optical measurement replaces that judgement with image processing. Foundrax has developed the BRINtronic family around the principle that the instrument should either return a valid result or flag the conditions that prevent one. Earlier systems already incorporated checks for surface quality and ovality, but RIVO packages the core functions into the microscope body rather than depending on external computing hardware.

The company traces the first BRINtronic to 1982, when the system was incorporated into the first generation BRINscan hardness tester and ran on a computer with 4KB of memory. Successive generations have added more processing power, faster image analysis, networking, automated reporting, and tighter integration with production machines. RIVO continues that development by concentrating more capability into less equipment.

Portable measurement is particularly useful where hardness testing cannot be confined to a laboratory bench. Large castings, forgings, pressure equipment, and heavy components may be impractical to move to a fixed optical station, while maintenance and field inspection can require a measurement system to travel to the part. Removing a separate controller and cable reduces setup work and makes the measurement head easier to use around components with limited access.

The instrument’s own illumination is also intended to standardise imaging conditions. Foundrax says no adjustment is required for ambient light or indentation size, reducing another source of setup variation. The refined RIVO algorithm is designed to reduce the effect of surface condition on the measured edge while still warning when preparation is too poor for a reliable result.

In production quality systems, a faster reading can affect more than inspection time. A hardness result can determine whether a heat treatment, forging, casting, or material batch proceeds to the next operation. Where testing sits inside a higher-volume workflow, repeated manual interpretation introduces labour and variation, while slow transfer of results can hold material in inspection rather than production.

Foundrax’s wider equipment range already integrates automatic BRINtronic measurement into production Brinell machines, including systems designed for large components and automated lines. The portable RIVO extends the same measurement logic to a standalone instrument, creating a route for plants that need automated optical measurement without installing a complete fixed tester at every inspection point.

Each unit is supplied with a charger, desk stand, external backup battery, safety wrist strap, rugged carry case, and PC software for downloading results. Foundrax says the package also includes a UKAS certificate of calibration to ISO 6506 and ASTM E10 and is available through the company and its international distributors.

Alex Austin, managing director of Foundrax, said the objective of successive BRINtronic upgrades has been to make the system faster and smaller. RIVO brings the camera, illumination, processing, and user interface into one housing while retaining the checks intended to prevent unreliable measurements from passing unnoticed.

The launch addresses the measurement layer on which larger manufacturing processes depend. Hardness testing is useful only when the result is repeatable, traceable, and practical at the point where a component is inspected. Foundrax’s latest design is intended to make that measurement less dependent on external hardware and operator interpretation while keeping the established Brinell method intact.
