Laser class 3R: only permissible for commercial use This digital tachometer with integrated laser and high-contrast, digital 5-digit, 13 mm, LCD display and blue backlight provides fast and accurate non-contact measurements of revolutions per minute and surface speeds of rotating objects. It combines a CPU, photoelectric technology and semiconductor laser technology in a single measuring device (PHOTO TACH., RPM&REV). The plastic enclosure with integrated, non-slip rubber protector is designed for both left-handed and right-handed users. It can be used for mobile measurements powered by a 9 V battery or stationary measurements using a 9 V mains adapter. - Laserklasse 3R: nur zur gewerblichen Nutzung zulässig - Two test modes: rotational speed mode (unit: RPM) & count mode (unit: REV (revolutions)) - Wide measuring range and high resolution - High-contrast digital LCD display and backlight - Integrated memory shows MIN. and MAX. values and the last saved value - Battery level indicator/auto-ranging Measurement functions and ranges: 2 - 99999 rpm; 0.1 rpm, ±0.05% + 1 digits Sampling rate: 2x/sec above 120 rpm Measurement range: 50 mm 500 mm Total rpm: 1 - 19.999 rpm; 0.1 rpm Supplied accessories: case, battery, reflective adhesive tape and instructions Laser: class 3R Output: < 5 mW Wavelength: 630 - 670 nm Operating voltage: 9-V battery Dimensions (W x H x D): 58 x 160 x 39 mm Weight: 150 g https://elecena.pl/product/18778195/2790-digital-tachometer-5-digit 2021-06-13 https://elecena.pl/product/18778195/2790-digital-tachometer-5-digit 2021-07-15 https://elecena.pl/product/18778195/2790-digital-tachometer-5-digit 2023-01-14 https://elecena.pl/product/18778195/2790-digital-tachometer-5-digit 2025-04-07 https://elecena.pl/product/18778195/2790-digital-tachometer-5-digit 2026-01-04
