Extech's 461750 is a great way to measure RPM levels via the use of direct contact.
Contact measurements are carried out via the use of surface wheels, which allow the unit to be used to capture readings of linear surface speeds in ft/min, m/min and yd/min. The device's measurements range is 10 to 20000rpm, 3 to 6560ft/min, 1 to 1999.9m/min and 1 to 5000yd/min.
An autoranging tachometer, the Extech 461750 automatically adjusts the range as necessary and relays test readings via the device's LCD screen with high accuracy of 0.1%. The unit also included an intergated finger guard to protect the user when measuring and the design of the unit makes it perfect for carrying around in a pocket.
