Extech RPM10 Photo/Contact Tachometer with built-in InfraRed Thermometer

This instrument combines a contact shaft tachometer, non-contact laser tachometer, surface-speed wheel adapter, and a built-in IR thermometer (with laser pointer and fixed emissivity) to measure surface temperatures from approximately -20 °C to +315 °C (-4 °F to 600 °F). The tachometer ranges cover about 0.5 to 20,000 rpm in contact mode and about 10 to 99,999 rpm in photo (laser) mode. The surface speed contact wheel mode covers up to ~6,560 ft/min (~2,000 m/min). The IR thermometer mode allows checking bearing, motor, or machine surface temperatures while simultaneously monitoring rotational speed—useful for maintenance diagnostics. The unit includes memory for last/min/max readings, a large five-digit LCD, double-molded housing for rugged use, and ships with surface-speed wheels, reflective tape, and carrying case.

Features

• Tachometer (photo mode) range: ~10 to 99,999 rpm; contact mode: ~0.5 to 20,000 rpm.

• Tachometer accuracy: about ±(0.05% of reading + 1 digit) with resolution of 0.1 rpm.

• Surface speed (contact) measurement: approx. 0.2 ft/min to 6,560 ft/min (≈0.05 to 1999.9 m/min).

• Built-in infrared thermometer: temperature measurement range approx. -20 °C to +315 °C (-4 °F to 600 °F) with laser pointer spot indicator and a fixed emissivity of 0.95.

• Large 5-digit LCD display for clear readout, and memory functions (last, min, max readings).

• Non-contact laser mode extends measurement distance (up to ~2 m in some configurations) for safer use.

• Portable handheld design with protective housing and included accessories (wheel adapters, reflective tape, batteries, case).
