2in1 Digital Handheld Laser Photo Tachometer Speed Tester Non-Contact & Contact RPM Gauge Range 2.5~99,999 RPM with 3pcs Reflective Tape

This is a digital, battery-powered portableoptical tachometer operates up to 500mm from a reflectivetarget using a laser light source1.Laser Photo (non-contact): It measures the rotational speed (RPM) using visible red lightbeam from a powerful LED. 2.Rotational Speed (contact):Measure the Rotational Speed (RPM) comes w/ contact tips that can be used to touch the rotating axle. 3. Surface Speed (Contact): precision wheel can measure meter per minutes (m/min). Note:Just attach a reflective sticker to the rotating part and point the beam on the mark froma safe distance., great when a reflective tape cannot be attached, e.g. due to grease or water.SpecificationsMeasurement Range: PHOTO/LASER : 2.5 to 99,999RPMCONTACT: 0.5 to 19,999RPMSURFACE SPEED: 0.05 to 1,999.9m/minResolution:PHOTO/LASER: 0.1 RPM (from 2.5 to 999.9 RPM)1 RPM (over 1,000 RPM)Resolution: CONTACT: 0.1 RPM (from 0.5 to 999.9 RPM)1 RPM (over 1,000 RPM)Resolution: SURFACE SPEED: 0.01 m/min (0.05 to 99.99 m/min)0.1 m/min (over 100 m/min)Accuracy: ±(0.05% + 1 digit)Sampling Time: 0.8 sec (over 60 RPM)Time base: Quartz CrystalSet Includes: 1 x 2-in-1 Digital Photo &Contact Tachometer 3 x Reflective Tape Mark (total600 mm) 1 x Contact speed measurement fitting 3 x Contact rotational speed measurement fitting 2 x ScrewEnglish Quick Start Guide Standard factory package
