Metron Markers™ provide precision-controlled ink delivery with a variety of tips, colors, and formulas—trusted across industries worldwide wherever accuracy and detail matter.

Industries We Serve

Aerospace

In aerospace, precision is mission-critical, and Metron products are built to meet that demand. Our markers apply bright, durable torque-seals that ensure fasteners stay secure and make breaks or tampering instantly visible. MiniMirrors™ extend inspection visibility into hard-to-reach areas, helping technicians spot defects and wear before they become risks.

Electronics

In electronics manufacturing, static safety and precision go hand in hand. Metron offers ESD-safe markers, inspection mirrors, and specialty fluids designed for PCB assembly, rework, and QA. Technicians rely on our electrostatic-safe MiniMirrors™ to inspect fine-pitch solder joints in tight layouts without risking static discharge. From marking to inspection, Metron tools help ensure product reliability and protect sensitive components.

Medical & Dental

In medical and dental settings, precision and cleanliness are essential. Metron markers, inspection mirrors, and specialty fluids support device assembly, maintenance, and quality checks where accuracy can’t be compromised. Technicians use our tools to apply fine, durable markings and to inspect intricate instruments or equipment components with confidence. By combining reliability with precision, Metron helps healthcare professionals maintain the highest standards of safety and performance.

Automotive

In the automotive industry, speed and accuracy drive every stage of production and maintenance. Metron markers and inspection mirrors support assembly, repair, and quality assurance with tools built for demanding shop-floor and trackside conditions. Race teams rely on our markers as torque seals, applying bright, durable colors that make fasteners easy to check under pressure. From the assembly line to competitive racing, Metron products help ensure safety, reliability, and performance.

Defense

We serve defense contractors with rugged marking and inspection tools designed for mission-critical applications. Metron MiniMirrors™ provide optically clear reflections, giving technicians reliable visibility for human inspection of components. Our specialty fluids support non-destructive soldering of metal parts in military systems, ensuring structural integrity without surface damage. From assembly to field maintenance, Metron products deliver the precision and durability defense demands.

Communications

In communications, precision tools help keep critical networks running smoothly. Metron Markers—a favorite in data centers—deliver vibrant, reliable markings that aid vibration checks and torque applications on small components. Our MiniMirrors™ provide ultra-clear reflections in confined spaces, making inspection and maintenance of hardware faster and more effective. From telecom equipment to network infrastructure, Metron products help technicians service and safeguard the systems that keep us connected.

Industrial

In industrial manufacturing, precision and efficiency keep production moving. Metron markers, torque seal solutions, solder flux pens, lube pens, and MiniMirrors™ support assembly, maintenance, and quality assurance with tools built for tough shop-floor environments. Our solder flux pens deliver consistent application without slowing technicians down the way felt pens can, our lube pens provide precise lubrication to keep machines humming, and our markers apply bright, lasting torque seals for quick verification. From heavy equipment to precision assemblies, Metron products help manufacturers reduce errors, improve traceability, and maintain compliance.

Art & Crafts

In arts and crafts, creativity demands precision and control. Metron’s vibrant markers deliver fine, detailed lines with brilliant color that artists and makers rely on for intricate work. Our adhesive markers make it easy to apply glue with pinpoint accuracy, keeping even the smallest parts secure without the mess. For projects with moving elements, our lubricant markers ensure smooth, squeak-free performance that keeps creations working as beautifully as they look.
