Handheld magnetic-pole identifier and tester for refractometer components and other magnetic parts. Designed to quickly find North/South poles and check magnetic properties in one compact instrument. Key benefits Eliminates guesswork: instantly identifies North and South poles so assembly and alignment decisions are fast and accurate. Consistent, repeatable readings: delivers reliable polarity classification for QA, calibration and maintenance tasks. Speeds workflow: compact, portable design supports quick checks on the bench or in the field, reducing downtime. Versatile compatibility: works with refractometer components, magnet arrays, sensors and other magnetic parts commonly inspected in labs and manufacturing. What it does Polarity detection: clearly identifies North and South poles and classifies magnet orientation for NS-oriented applications. Magnetic-property testing: verifies magnetic behavior needed for assembly, calibration and functional checks. Portable measurement: handheld format provides improved measurement precision compared with ad hoc methods while remaining easy to carry and position. Key features and attributes Function: combined pole identifier and magnetic tester in a single handheld tool. Size and portability: compact, lightweight design for bench use, production lines, and field service. Performance: reliable, repeatable readings that support fast decision making during assembly and QA. Durability and storage: supplied with a protective box for safe storage and transport; built for repeated use in lab or workshop environments. Compatibility: appropriate for lab technicians, manufacturing technicians, maintenance staff and field service personnel who need fast polarity checks. Practical applications (specific use scenarios) Quality control during magnet assembly or calibration of refractometer components: verify pole orientation and magnetic integrity before final assembly. Polarity verification for magnet arrays used in sensors or optical instruments: confirm correct NS alignment to prevent sensor errors or optical misalignment. On-site field checks of magnet orientation: perform quick checks during installation or maintenance to ensure systems operate as intended. Who should use it Lab technicians performing component checks and calibrations. Manufacturing and assembly technicians validating magnet orientation on the line. Field service and maintenance personnel needing fast, portable magnetic checks. What you get One compact handheld magnetic pole identifier and tester. Protective storage box for transport and safe storage. A durable instrument designed for repeated use in lab, workshop, or field environments. No special training required; designed to integrate into existing inspection and maintenance workflows to improve speed, accuracy, and consistency without complicating procedures.
