Handheld instruments


competitor instruments due to its simple, lightweight design and ability to detect mercury within three seconds, as well as the after sales service and technical support,” Yu adds. Mercury intrusion porosimetry (MIP) is a technique used for the evaluation of porosity, pore size distribution, and pore volume (among others) to characterise a wide variety of solid and powder materials. The porosimeter employs a pressurised chamber to force mercury to intrude into the voids in a porous substrate. As pressure is applied, mercury fills the larger pores first. As pressure increases, the filling proceeds to smaller and smaller pores. ION Science’s MVI is a revolutionary handheld instrument that can detect mercury in just three seconds. Ergonomically designed for simple, one-handed operation, it is the ideal survey unit for rapid and reliable mercury detection. It helps to pinpoint mercury sources in even the most challenging environments. The MVI’s dual beam UV technology eliminates the problem of saturation and the need for regeneration between readings, maximising its availability and uptime. A high- performance pump ensures fast indication and recovery and the instrument’s audible alarm and large digital display clearly indicate the levels of mercury present. Fast and accurate, ION Science’s MVI


provides continuous readings and offers two detection ranges of 0 – 200 μg/m3 0.1 μg/m3


(res. ) and 0 – 2,000 μg/m3 (res. 1 μg/m3


These two ranges provide critical coverage for the OSHA PEL at 100 μg / m³ and the IDLH at 1,000 μg / m³. Yu concludes: “The ION Science MVI


operates very well and provides fast, accurate results. Based on our experience so far, I would be pleased to recommend it to other manufacturing businesses.”

DEFECT DETECTION IN THE PALM OF YOUR HAND


ndustrial metrology specialist, The Sempre Group, has introduced the new GelSight Mobile handheld sensor to the UK and Irish markets. The portable device collects 3D surface topographic data using an elastomeric sensor, which means it effectively reveals detailed surface features, no matter the lighting conditions or reflectivity of the material. GelSight Mobile allows users make repeatable measurements in seconds, while maintaining micron-level precision. Manufacturers can use this technology on any surface for extremely detailed and rapid surface measurement well as aftermarket care, defect detection and maintenance. The GelSight device uses an elastomer gel that reacts instantaneously to any surface on contact, revealing detailed topographical features including scratches, dents, surface roughness, corrosion and texture. This information is then used to generate a high- resolution 3D depth map, providing information on position and other derived surface measurements. The ability to instantly zoom in on

parts allows operators to gain incredibly detailed and reliable micron-level measurements to check for quality. For example, engineers can zoom in on any material to find any microscopic material damage. This gives users the opportunity to carry out instant pass or fail inspections and understand whether


further maintenance is required, increasing throughput for high-cost parts and reducing downtime.


“GelSight Mobile is a valuable tool for


any manufacturer looking for a non- destructive and reliable way to gain accurate, immediate and repeatable 3D data for entire surfaces,” explained Mike G John, head of engineering at The Sempre Group. “Operators in aerospace and automotive manufacturing need the ability to quickly identify if a vehicle passes inspection or has anomalies. Destructive methods are effective but lead to increased scrap and waste. GelSight is a clean, easy way to reduce downtime in these applications. “Particularly for those working with large parts, the convenience of a handheld device that can be operated using a tablet is incredible,” added Mike G John. “GelSight’s use of elastomer gel also makes the tool very versatile, it can be used as effectively on an engine blade as it can on a car window without sending parts off-site.” Manufacturers will also be able to use the data generated during defect detection to enhance the reliability and accuracy of their documentation. Storing quantifiable micron level data can later aid businesses during audits or when verifying their product’s quality to clients.
