Laser Distance Meter for Field Work

The Olufey US-NK50A measures distance, area and volume up to 165 feet with an accuracy of ±0.08 inch. It suits surveyors, landscapers and tradespeople who need quick on-site readings without a tape measure.

IP54 Rating and Fast Operation

The unit carries an IP54 rating for dust and water resistance plus shock protection. A Class II laser at 620-670 nm delivers a reading in 0.5 seconds, while the auto-off function conserves the two 1.5 V AAA batteries during normal use.

Questions about this item

How do I install the batteries and set the reference point before measuring?

Open the battery compartment, insert the two supplied 1.5V AAA cells observing polarity, then press the benchmark button to choose front or rear reference so the 165ft range reads from the correct edge.

What will need replacement after extended use?

The two 1.5V AAA batteries are the only consumable; the IP54-rated ABS housing and Class II laser module are sealed and have no user-serviceable parts.

At what distance does the ±0.08in accuracy limit become the limiting factor?

The ±0.08in (±2mm) tolerance applies across the full 0.5ft to 165ft range, so it is the first limit you encounter at any distance.
