Specification: Measurement range: Photo tach: 2. 5 to 99, 999 RPM Contach tach: 0. 5 to 19, 999 RPM Linear speed: 0. 05 to 1, 999. 9(meter/min) Linear speed distance: 0. 02 meter(0. 05 to 99, 999m) Resolution: Photo tach: 0. 1RPM(2. 5 to 999. 9 RPM); 1RPM(over 1, 000 RPM) Contach tach: 0. 1RPM(0. 5 to 999. 9RPM); 1RPM(over 1, 000 RPM) Linear speed: 0. 01 meter per min(0. 05 to 99. 99 m/min); 0. 1m/min(over 100m/min) Linear speed distance: 0. 02m(0. 05 to 99, 999m) Time Base: 6MHz Quartz crystal Display: 5 digitals, digital numbers high up to 0. 7 inches Accuracy: +(0. 05% + 1 digit) Sampling Time: 0. 8 sec. (over 60 RPM) Test Range select: Automatic Memory: Automatic memory maximum, minimum and the last reading Effective Distance: 2 to 20inch/50 to 500mm(photo tach) Power Consumption: Approx. 30mA Battery: 4x1. 5V AA(included)/6V direct current stable voltage power Size: 8. 3x2. 9x1. 5inches/210x74x37mm Operating Temperature: 32 to 122F/0 To 50C Package Content: 1 x Carrying Case 1 x Bolt bag 1 x Operation maunal Reflecting tape marks length 23. 6inches 1 x Linear speed measurement fitting 3 x Contact rotational speed measurement fitting 1 x Non-contact Photo Tachometer
- - 2 in 1 Contact Digital Tachometer and Non-Contact Photo Tachometer RPM Tach Meter.Contact and photo part can be switched at any time.Extra large 5-digit LCD display,digital numbers high up to 0.7 inches.Contact function measure linear and rotation speed,non-contact photo tachometer.Laser Class II;Laser power less than 3mW;Wavelength is 650nm-670nm.
- - Note:The non-reflective area must always be larger than the reflective area,if the shaft is reflective,it must be covered with black tape or black paint before attaching tape.Shaft surface must be clean and smooth before applying tape.
- - The last value, max value, min value will be automatically stored in memory automatically and can be obtained by pressing Memory Call Button anytime.Photo Range:2.5 to 99,999 RPM;contach tach range:0.5 to 19,999 RPM;linear speed:0.05 to 1,999.9(meter/min);linear speed distance:0.02 meter(0.05 to 99,999m).
- - Very low speed masurement:It is recommended that you can put more than one reflective mark on the object averaged,the real vale equal to displaying value replcvtive mark.Contact accessories include small and bigger taper,the larger is suitable to measure low speed and the smaller for high speed.For long time storage,please take out the batteries from the Tachometer.
- - What you will get:1xlinear measurement fitting,3xrotation speed measurement fittings,1xnon-contact photo tachometer,1xcarrying case,reflective tape:23.6inches,1xopetation manual,1xbolt bag.
