NT-6580 Laser Distance Measurer measures distances up to 80 meters
in just one second with 2.0 millimeter accuracy. It’s integrated with a
worldwide unique feature: Numeric Keypad.
NT-6580 is the world’s leading laser distance measurer integrated with
numeric keypad, which works as a calculator, also computes measured
data. It’s efficient and convenient, saves your time and trouble for data
processing and notes taking.
Other features that come with NT-6580 are also helpful and easy to use
include:
360° tilt measurement
NT-6580 measures inclination up to 360° range, so that distance to
inaccessible objects can be measured using trigonometric function.
Looks and feels fantastic
NT-6580 housing is designed like a sports car, and it adopts double
injection technology, ABS+TPU materials, offers a gorgeous
appearance and comfortable touch feeling.
WARNING: Failure to follow these safety instructions could result in fire,
electric shock, or other injuries, or damage to NT-6580 Laser Distance
Measurer or other property. Read all the safety information below before
using NT-6580.
Laser classification
NT-6580 uses a visible laser beam which emerges from the front of the
instrument.
Laser Class 2 products:
Do not stare into the laser beam or direct it towards other people
unnecessarily. Eye protection is normally afforded by aversion responses
including the blink reflex.
WARNING:
Looking directly into the beam with optical aids (e.g. binoculars,
telescopes) can be hazardous. Do not look directly into the beam with
optical aids.
Looking into the laser beam may be hazardous to the eyes. Do not look
into the laser beam. Make sure the laser is aimed above or below eye
level.

Indirect Measurement
This device can measure distance to inaccessible points, such as the
distance to a wall which is blocked by obstacles, or the height of a tree,
using trigonometric function.
To ensure measuring accuracy, indirect measurement should be based
on the following conditions:
(1) The measuring points of the object which is to be measured should be

Calculator in Measuring
When a measurement was taken, and user enters into calculator mode,
the device will use the measurement result as an original data to do
calculation. User can also edit original data, such as press backspace ← to
clear digital, or use numeric keypad to add digital, or even press
re-measure.
When the original data was confirmed, user presses operational character
(+,-,*,/),then uses numeric keypad to input new digits or press
new measurement, the results of calculation will be seen on display after
user presses the Equal Sign=.
This process can be repeated as required.

illumination, 25°C.
[2] Applies for 10 to 500 % target reflectivity, high background illumination,
-10°C to +50°C.
[3] Tolerances apply from 0.2m to 10 m with a confidence level of 95 %.
The tolerance may deteriorate to 0.15 mm/m between 10 m to 30 m
and to 0.2 mm/m for distances above 30 m
[4] In favorable conditions (good target surface properties, room
temperature), measuring range is up to 80m. In unfavorable conditions,
such as intense sunshine, poorly reflecting target surface (black surface) or
high temperature variations, the deviation over 10m distance may
increase.
10. Care
Do not use aggressive cleaning agents or solutions.
