The laser used in the distance meter is not only used for targeting, but also for emitting laser pulses of predefined wavelength and frequency. The laser pulse is fired at the target, and the returning laser pulse is received by the distance meter (very fast, actually the speed of light). The difference in the original pulse wavelength and the returning signal is proportional to the distance between the laser distance meter and the target. HOLO laser distance meter 120m quickly calculates this difference and displays the distance between the distance meter and the target with an accuracy of up to 2 mm.
Why is the laser distance meter a new type of distance measurement technology?
1. Speed: With a laser distance meter, just aim at the target, press a button, and you will get the measurement result.
2. Accuracy: The accuracy is within 2mm. There will be no bending problem which is common to tape measures.
3. Independent operation: no need for a partner to hold the other end.
4. No ladder required: safe measurement of hard-to-reach parts.
5. Convenience: Measure parts that were difficult to measure in the past, such as ceilings or other equipment.
6. Distance: Measuring 120 meters is as convenient as measuring 10 meters.
How to use the laser distance meter 120m ？
1. Place the laser distance meter against a wall, on a base plate, or simply hold it in your hand.
2. Press the distance button to turn on the laser.
3. Aim at the target, press the distance button again, and then read the measured reading directly from the screen.
4. When measuring area, press the area button to measure the length and width, and the laser distance meter automatically calculates the area.
5. When measuring volume, press the volume button to measure the length, width and height.
6. If you need to add or subtract distances, first measure a distance, then press the plus or minus sign, and then add or subtract the next distance. Using this function, you can measure circumference, non-straight distance (add multiple short distances) and direct measurement (measure the entire paragraph, subtract one paragraph, and get the remaining distance)
