Key benefits Clear readings with Data‑Hold function: freeze measurements on screen to read values easily and avoid errors while recording or adjusting parts. Secure, hands‑free placement: strong built‑in magnets fasten the device firmly to metal surfaces so you can work with both hands. Flexible measurement modes: switch between relative and absolute measurement conversion to compare offsets or return to a known reference quickly. Versatile for professional environments: designed to support automotive, woodworking, mechanical, machine, and medical applications where reliable, repeatable measurements matter. Features and how they solve problems Data‑Hold function — prevents misreading during tight-space work or when transferring values to documentation, improving accuracy and workflow speed. Strong magnets — keep the tool fixed to ferrous surfaces so you don’t need clamps or an extra pair of hands; ideal for angled or vertical setups. Relative & absolute measurement conversion — use absolute mode for baseline measurements and relative mode to measure differences or set zero points for quick part comparisons or adjustments. Performance and compatibility Function: measurement with Data‑Hold and selectable relative/absolute modes for flexible use. Compatibility: attaches directly to metal surfaces via strong magnets; suitable for use across automotive, wood, mechanical, machine, and medical settings. Reliability: engineered to provide stable readings during common workshop and field tasks where secure mounting and readable data are required. Typical use scenarios Automotive repair: attach to a chassis or engine component to hold a reference measurement while aligning parts or checking clearances. Woodworking and machine shops: fix to metal jigs, fixtures, or machine beds to maintain consistent setup dimensions during milling, routing, or repeatable cuts. Medical and precision equipment servicing: secure to metal housings or frames to record offsets and confirm adjustments without losing the measured value. Why choose this tool Minimizes handling errors by combining readable display retention and magnetic mounting. Simplifies repeated tasks with relative/absolute conversion, saving time during setup and inspection. Practical across multiple industries where metal mounting and reliable measurement data are needed. Included functions (as specified) Data‑Hold for easy reading Strong magnets for firm attachment to metal surfaces Relative and absolute measurement conversion Applications Automotive, woodworking, mechanical industry, machinery maintenance, medical equipment work.
