The Extech RPM10 tachometer provides wide rpm (photo and contact) and linear surface speed (contact) measurements. The Extech RPM10 tachometer features a built-in IR thermometer with laser to measure remote surface temperature on motors and rotating parts. The infrared thermometer has a wide temperature range of -4 to 600°F (-20 to 315°C) with a fixed 0.95 emissivity and 6:1 distance to target ratio.

As a tachometer, the Extech RPM10 tachometer has a range of 10 to 99,999 rpm in photo mode and 5 to 20,000 in contact mode. The Extech RPM10 tachometer is accurate to 0.05% with a maximum resolution of 0.1 rpm in either photo or contact mode.

The Extech RPM10 tachometer has a large 0.4" (5 digit) LCD display. The non-contact photo tachometer uses a laser for greater measuring distance up to 6.5 ft (2m). The contact tachometer is used for RPM and surface speed measurements. The Extech RPM10 tachometer's memory stores min/max/last readings for convenient data analysis and recall. The characters on display reverse direction depending on the selected mode. The Extech RPM10 tachometer is contained in double molded housing and ships complete with tips/wheel, four 1.5V AA batteries, reflective tape, and carrying case.
