Digital plan measure for construction takeoffs

The Calculated Industries 6135 is a hand-held scale tool built for fast, accurate material takeoffs from blueprints. It stores 91 built-in metric and imperial scales plus eight custom scales. A 7-digit main LCD shows measurements while a 3-digit counter and 5-digit scale display keep reference data visible. Power comes from two included CR-2032 lithium cells.

Estimators and contractors who scale drawings

Professionals who regularly quantify linear dimensions from paper plans will benefit from the dedicated length and width keys, auto-count feature and memory function that create a permanent record of every dimension. Workers who only measure on-site with a tape or who need area and volume calculations directly from the instrument should consider a different tool.

99.8 % mechanical accuracy with 2-4 % user variance

The wheel mechanism delivers 99.8 % mechanical accuracy, though real-world results typically vary by 2-4 % depending on plan quality and tracing technique. This single figure determines whether the instrument meets the tolerance required for a given bid or estimate.

Questions about this item

What are the exact dimensions of the 6135 so I know if it fits my pocket or desk tray?

The unit measures 7.30 inches long, 1.90 inches wide and .60 inches thick.

How do I install the two CR-2032 batteries that power the LCD, and what step do people miss?

Slide off the rear cover, insert both cells with the positive side up, then replace the cover; the step often missed is checking that the display powers on before starting a takeoff.

When will I need to replace the CR-2032 cells and is any other upkeep required?

Replace the two lithium batteries when the LCD dims or readings become erratic; no other periodic maintenance is needed for the 6135.
