MEASUREMENT RANGE0.15 to 40 m; Precision laser rangefinder: +/- 2mm (accurate to 3 decimal places); 20 data memories, switchable units (M/FT/IN); The digital laser meter can complete most measurements in 0.5 seconds EASY OPERATIONPress one button, you can quickly check the height, length, area and volume of the object or building; 4Digital laser rangefinder is ideal for home decoration, especially in large areas such as apartments, buildings, real estate, factories, warehouses, construction and industries MEASUREMENTS MULTIPLE PRACTICESThe laser meter has different measuring modes, Measuring distance, area, volume with precision; Pythagorean function (indirect measurement); Continuous measurement function, Add or subtract measurements; Min and max value TECHNICAL FEATURESMute function to avoid noise; 4 lines of LCD display, large screen with backlight; IP54 (splash-proof and dust-proof); portable non-slip handheld design; 20 data records and recall function which are useful for review and calculation; low battery indicator; 180s automatic shutdown to save energy, can work up to 5000 times Mileseey Laser Meter 40M: This premium rangefinder uses the X5 intelligent ranging algorithm, filtering algorithm and spectroscopic lens technology so you can enjoy: Ultra- rapid measurements of 0.5 seconds Accuracy +/- 2mm (accurate to 3 decimal places) Single / continuous measurement Of 20 sets data storage 1.6 inch LCD screen with intelligent backlight. Switchable units (M/ FT/IN) IP54 (anti- splash and dustproof) Mute function to avoid noise Manual calibration 1.6 intelligent backlit LCD screen in 1.6 inch LCD screen with intelligent backlight, it is better able to resist strong light interference and can still be read clearly under external sunlight, which provides more stable measurement and accurate than other laser measurements. Simple operation: just press a button for single/continuous measurement. 20 sets of data storage and mute function< /p> 20 data records and callback function which are useful for review and calculation; This means easy access and optimal storage space for all your measurement data sets. Mute Function: For even more convenient use when you need to stay quiet (e.g. in schools, libraries or similar projects), you can control the sound and take advantage of silent mode. Professional high-precision Laser Range Finder Laser meter uses a spectroscopic lens, which is a special free-surface optics that has high transmittance and high refractive index. This means you can make different measurements quickly and accurately. Protected the lens with PC hardware, so you can enjoy many years of use. And with the soft 280 degree adhesive hollow-out design, you get a device that is durable, drop-proof and wear-resistant, lightweight and easy to hold. Delivered quantity: 1 piece Welcometomeet
