Long-Range Laser Distance Measurement
The Fluke 424D can measure distances up to 100 m (330 ft) when used with the specified Leica GZM26 target plate. Its typical range is 80 m (260 ft), while unfavorable conditions can reduce the range to approximately 60 m (195 ft).
The typical measuring tolerance is ±1.0 mm, providing precise measurements for building, maintenance and industrial applications.
180° Inclination Sensor
The built-in 180° inclination sensor allows the Fluke 424D to measure tilt and calculate distances in situations where a direct measurement may not be possible.
The tilt measurement range is 360°, with a specified measuring tolerance of ±0.2°.
Built-In Compass
The integrated compass provides heading information for distance measurements.
Combined with the inclination sensor and indirect measurement functions, this allows the Fluke 424D to perform measurements in locations where direct access is limited.
Pythagoras and Indirect Measurement
The Fluke 424D includes enhanced Pythagoras calculations for determining distances indirectly from other measurements.
This is useful when measuring:
Building heights
Wall heights
Roof structures
Hard-to-reach points
Horizontal distances
Diagonal distances
The minimum/maximum tracking function can also help measure horizontal and diagonal distances from a stable measurement position.
Area and Volume Calculation
The Fluke 424D can automatically calculate:
This reduces manual calculations when measuring rooms, buildings and other spaces.
Addition and subtraction functions are also available for combining or comparing measured distances.
Automatic End-Piece Correction
The integrated end-piece sensor automatically detects the position of the measurement bracket and adjusts the reference point.
This is particularly useful when measuring from:
Corners
Edges
Wall surfaces
Building structures
It helps reduce measurement errors caused by selecting the wrong reference position.
Large Four-Line Backlit Display
The Fluke 424D features a large four-line backlit display designed to improve visibility when working in low-light conditions.
The display provides clearer access to measured values and calculation results during field measurements.
Stake-Out Function
The built-in stake-out function allows users to define a required measurement length and use the instrument to identify the corresponding points.
This can be useful for:
Construction layout
Installation work
Equipment positioning
Building measurements
Repetitive distance marking
Measurement Memory
The Fluke 424D stores the last 20 measurements, allowing users to quickly recall previous results without manually recording every measurement.
Tripod Mounting
For long-distance measurements where a stable reference position is important, the Fluke 424D can be mounted on a tripod.
This helps improve measurement stability when working over longer distances or performing repeated measurements.
Rugged Field Design
The Fluke 424D has an IP54 protection rating against dust and water spray.
The instrument operates from -10 °C to +50 °C and is designed for portable field measurement. Its compact dimensions are 127 × 56 × 33 mm, with a weight of approximately 158 g including batteries.
Battery Life
The Fluke 424D uses two AAA batteries and can perform up to approximately 5,000 measurements.
Automatic laser shutoff occurs after 90 seconds and automatic power-off occurs after 180 seconds to help conserve battery life.
Applications
The Fluke 424D is suitable for:
Construction measurement
Building inspection
Facility maintenance
HVAC installation
Electrical installation
Industrial maintenance
Equipment installation
Interior measurement
Building height measurement
Distance and area measurement
Construction layout
