Scale Master Pro

Digital Plan Measure

Specifically designed to simplify takeoffs from architectural and engineering drawings, the Scale Master Pro finds linear measurements of any shape--as well as rectangular areas and volumes--and it converts between scales and dimensions.

It comes with 72 built-in scales (39 U.S. and 33 metric for maximum versatility). It also features six custom scales (three each for U.S. and metric units), enabling you to define any scale, even from plans that have been reduced, enlarged, or are just out of scale. You can easily store the new scale permanently into the device for future use.

Other features include two built-in memories; dedicated length, width, and height keys; push-button counter to keep track of items while rolling; switch for locking in mode, scale, and units while rolling; and a subtract key that allows you to deduct rolled distances. Easy to learn and use, the Scale Master Pro will save you time and reduce errors on your estimates and bids.

For contractors, estimators, engineers, landscapers, pipeline builders, excavators, HVAC contractors, pavers, electrical contractors - anyone needing fast, accurate takeoffs from plans and blueprints.

  • Get instant linear, rectangular area and volume take-offs; use it like a pen - just roll and measure
  • Convert between scales and dimensions
  • Six user-set custom scales. Calibrates to any plan and then stores that scale for future use. Perfect for scaling faxed or out-of-scale plans.
  • Calculate rectangular areas/volumes (LxWxH). Roll and enter length of room, then width and instantly calculate square footage.
  • 72 built-in scales; 39 U.S. (feet-inch) and 33 metric.
  • Multiple dimensional units for versatility; select the measurement units you use: decimal feet, feet-inches, decimal inches, yards, millimeters, meters, kilometers - including square and cubic formats
  • Subtract and Counter feature lets you subtract if you roll too far. Also lets you count items (e.g., studs, outlets, etc.) and accumulate in memory.
  • Easy-to-read dual display shows your measurement in feet/inches or metric

Great tool that used to be for sale pretty much everywhere and is now awfully hard to find. Previous one served well for over 10 years, unluckily its wheel gave out and I couldn't find a replacement part.

Luckily I found a new measuring tool here, ordering worked out quickly and easily.

The tool has been very good in use with a minor detail being scale switching, as I have to change tab (ARCH -> ENG) to get from 1:50 scale to 1:100/200.

Excellent tool for heavy use, the paper plans are still very much alive and this is a thing you can't work without.

I obtained a replacement wheel for the product as I had not been able to use it for some time due to damage to the wheel. I value the use of the product for my field work and it has proven to be invaluable to me in my role.

This is a wonderful product. All of our estimators use them and new ones that come that have never used them love them also.
