Aluminum Ruler with 650nm Wavelength

Product Detailed Description

A quick measurement across the workshop bench, a straight line down a layout sheet, then a bright red reference point projected on the far wall - that is the kind of workday this aluminum ruler with built-in laser was made for. The metal body gives it the rigid, lightweight feel drafters and engineers expect from a desk or tool-bag instrument, while the printed graduations stay legible through daily handling.

At its core sits a compact laser module rated at 650nm wavelength and under one milliwatt of output, running on two LR3 batteries. That low-power rating suits an office or classroom environment as well as field use, letting users mark a level reference line or a straight guide without carrying a separate tool.

Promotional distributors often pair laser rulers with conference giveaways and trade-show kits, since the combination of measuring aid and pointer gives end users an everyday reason to keep the logo in view. Confirm scale markings and edge clarity before committing a wholesale order.
