Distance meter Proline 15174 — handheld laser measuring device, single unit

Proline 15174 is a handheld laser distance meter supplied as a single unit for rapid linear measurements. The compact instrument delivers laser-based distance checks with a measurement time of approximately 0.5 s and supports a range of common measuring functions useful on construction sites, during installations, and for home projects. The device features a backlit screen, internal storage for up to 20 measurements and an automatic switch-off after 180 seconds to preserve battery life.

Advantages

The Proline 15174 offers quick and reliable single and continuous measurements with a Class II 635 nm laser operating at under 1 mW. It includes practical calculation modes: direct and indirect Pythagorean measurements, surface area and volume calculations, and the ability to add or subtract measured values. The instrument records up to 20 readings, supports three selectable measurement start points (front, back or case foot for corner measurements), and measures plane inclination angle. Compact dimensions and low weight make it easy to carry and operate in tight spaces.

Suitable for

• Room layout and interior measurement
• Installation and fitting of fixtures and furniture
• Basic site surveys and quick distance checks
• Area and volume calculations for material estimates
• Indirect height measurement using Pythagorean functions

How to use

Switch on the Proline 15174 and select the required measurement mode using the device controls. Choose the appropriate measurement start point (front, back or case foot) depending on whether you measure from an edge, from the instrument body or from a corner. Aim the laser at the target surface and press the measurement button; results appear on the backlit screen quickly. For indirect height or inaccessible distances, use the Pythagorean functions as described in the manual. Use the add/subtract feature to combine multiple readings for cumulative distances or cut lists.

Usage recommendations

Use AAA alkaline batteries for best runtime and remove batteries if the device will be stored for long periods. Avoid pointing the laser at people or reflective surfaces; follow local safety rules for Class II lasers. Store the instrument within the recommended temperature range and keep it in its case when transporting to protect the optics and housing.
