New Fluke 421D Laser Distance Meter talks technicians through measurements with extended 100-metre range

New Fluke 421D Laser Distance Meter

Sydney, October 21, 2009 – Fluke Corporation, the global leader in portable electronic test and measurement technology, has introduced its most advanced and capable distance measurement device, the Fluke 421D Laser Distance Meter.

Its advanced features include audible feedback for taking room angle and incremental measurements, a +/- 45 o tilt sensor for taking indirect measurements in hard-to-reach areas and enhanced Pythagoras calculation for indirectly determining distance.

The Fluke 421D Laser Distance Meter can measure distances of up to 100 metres with one push of a button and automatically stores the last 20 measurements for quick recall of previous measurements.

Laser distance measurement technology makes the Fluke 421D Laser Distance Meter far more accurate and dependable than devices using ultrasonic technology. It is IP54 rated for resistance to water spray and dust.

Like other Fluke distance meters, the Fluke 421D Laser Distance Meter helps electricians, facilities managers and HVAC contractors save time and labour.

Instead of walking back and forth across a space with tape or wheel, the user can simply place the meter at the starting point, point the laser at the target, press one button and instantly read the distance, without the help of a second person to hold the other end of the tape measure.

The Fluke 421D Laser Distance Meter has a bright laser for easy targeting and large liquid crystal display with buttons positioned for one-hand operation. The simple user interface lets technicians easily add or subtract measurements and quickly calculate area and volume. An automatic shut-off feature improves battery life, providing up to 5000 readings from two AAA batteries.

The Fluke 421D Laser Distance Meter helps technicians boost productivity and save money by helping speed up the measurement process and eliminate costly estimation errors. They are built to withstand a drop of approximately 1.2 metres and feature the ruggedness and reliability professionals expect from Fluke.

Laser technology: far ahead for measuring distance
Laser distance meters emit light pulses with a defined wavelength and frequency. The laser beam is reflected off the target and back to the distance meter at the speed of light. The returning wavelengths and light pulses change in relationship to the ones sent out by the meter. The difference between the two signals is proportional to the distance to the target.

Unlike ultrasonic meters, the laser distance meter’s narrow laser beam prevents reflection off objects that aren’t targeted, avoiding false readings. Laser distance meters are more accurate and reliable and measure much longer distances than ultrasonic meters.
