Extech 461893 Photo Tachometer

Non-contact rpm measurements to 99,999rpm with integral light beam

Make non-contact rpm measurements of rotating objects

Use reflective tape on object to be measured and point the integral light beam

Ideal measurement range up to 6-Inch (152mm) distance

Readings updated every second

All tachometers are microprocessor based with limited memory capabilities. Memory stores the final reading, as well as the last minimum and maximum-recall readings at the touch of a button. Both the contact and optical tachometers feature a large, five-digit LCD. Contact Tachometer Use this digital contact model with either a concave or convex tip to measure the speed of rotating objects (rpm measurements). Use unit with the linear speed wheel to measure surface speeds (ft/min or m/min measurements). Tachometer automatically suppresses insignificant zeros to provide precise rpm readings. Optical Tachometer Use the digital optical model to take noncontact speed measurements of rotating objects (rpm measurements). Tachometer uses a reflective mark and an integral light beam to provide precise readings. Display updates once every second. Autoranging function switches between two ranges: 5 to 999.9 rpm or 1000 to 99,999 rpm for greater accuracy. Simple operation and low cost make these tachometers ideal for general use
