Whether you are measuring length, area or volume, you can count on perfect precision. With a range of up to 40 meters and high accuracy (±2 mm), the device will work well for both professional work and home projects.
Gravity sensor for added convenience
The rangefinder is equipped with an easy-to-read 1.3" HD IPS screen that accurately displays all key information. In addition, the device features ROHM's 360-degree gravity sensor, which automatically rotates the screen according to the rangefinder's position. No more tilting your head, from now on you can comfortably read data regardless of the position you are in!
Versatility of measurements and additional functions
The FNIRSI IR40 supports multiple measurement modes, including single, multiple, area, volume, Pythagoras, as well as measurement relative to the front and back edges and changing units. The device opens up many conveniences for you - import photos, mark dimensions and draw on the screen. Automatic annotation of measurement results on technical drawings allows precise space planning effortlessly. Everything you need can be found in one device.
Small dimensions, many possibilities
The compact case (19 x 34.5 x 79 mm) with a pleasing curved design houses a 400 mAh lithium battery. The device can be charged via a USB-C port, and one full charge is enough for up to 3,000 measurements. This ensures that the tool is always ready to work, and will last you for years to come. The dual handle design and one-click measurement start-up make using the FNIRSI IR40 fast and comfortable - ideal even in dynamic working conditions. Connect the rangefinder to a dedicated Android or iOS app to forget about manual note-taking. Synchronize data in real time, add comments, draw room plans, calculate length, area and volume - all available from your smartphone.
