Unopened product, repackaged in our warehouses, in perfect working condition, warranty available. 【HIGH ACCURATE MEASUREMENTS】The laser distance meter with upgraded electronic angle sensor is more accurate than bubble levels, offering more precise angle measurements. The electronic angle is displayed in real-time, making it easier to find the horizontal direction. Reliable length measurement from 0.2 m to 50 m / 165 feet with a measurement accuracy of ±2 mm. One-click button unlocks units in m / ft / in / ft + in; 【MULTIFUNCTION】Automatic summation function with one touch, such as length measurement, area determination, volume calculation, indirect measurement (Pythagoras), continuous distance measurement with min. and max. Meets your various requirements for home, construction and industry, especially in large areas such as rooms, apartments and buildings, real estate, factories, warehouses etc. 【LCD display and silent mode】Turn off the beeper by turning on/off button 1. The large backlit LCD screen ensures reliable measurement results. 30 data records and recall function, useful for checking and calculating; 3 minutes without use, automatic shutdown avoids power consumption. 【COMPACT & PORTABLE】IP54 dust and water resistant ensures maximum protection in tough working conditions. The portable size and hard rubber casing ensure a good grip; the included wrist strap is available to prevent slipping. 【SCOPE OF DELIVERY & WARRANTY】1 * 50M / 165ft distance meter; 2 * AAA batteries; 1 * User manual, 1 * Portable bag. Product description Higher accuracy, higher efficiency Two levels provide more accurate measurement than an air bubble. Measuring range up to 165 feet, remarkable accuracy can reach ±1/16 inch; Fast measurement speeds significantly improve your work efficiency. Measuring range: 50 m Distance measurement accuracy: ±1/2 mm (±1/16 inch) Units: M / In / Ft / Ft + In Level / laser type: Class II / 630-670 nm, <1 mW Historical memory: 30 sentences Laser auto-off: 30 s Instrument auto-off: 180 s 4 unit conversion Hold down the unit button for 2 seconds to freely switch the units in M / In / Ft / Ft + In. which can meet your different measurement needs. Electronic angle sensor Compared to traditional physical liquid level bubble, the electronic angle sensor can display the measurement angle in real time. which makes it easy to find the horizontal direction makes the measurement data more accurate. 4 Unit Conversion Hold down the unit button for 2 seconds to freely change the units in M / In / Ft / Ft + In. which can meet your different measurement needs. Durable spectroscopic lens The laser meter uses a spectroscopic lens for fast measurements and high accuracy. This is a special free-surface optics with high permeability and a high refractive index. This means you get all types of measurements quickly and accurately. The products use PC material to protect the lens, which is more durable. Silent If you work in a quiet public place, you can put the laser meter in silent mode. Silent mode allows you to work in quiet environments such as libraries, offices and classrooms. IP54 Waterproof and dustproof The laser meter is made of robust and durable material with an IP54 protection class, which makes it more durable and comfortable to work in a variety of environments.
