The Extech 461995 Combination Contact/Laser Photo Tachometer provides both contact (0. 5 RPM to 19,999 RPM) and non-contact (10 RPM to 99,999 RPM) RPM measurement functions for use in virtually all applications. Laser guided non-contact measure up to 2 m (6.5 ft) away for added safety and convenience. Comes with wheels for linear surface speed or RPM measurements, 4 AA batteries, 0.6 m (23 in) reflective tape, carrying case, and user manual.

Features:

• Unique display where characters reverse direction depending on measurement mode you are in
• Large 0.4" (5 digit) LCD display
• Microprocessor based with quartz crystal oscillator to maintain high accuracy
• Tachometer memory stores last, max and min readings
• Provides wide RPM (photo and contact) and Linear Surface Speed (contact) measurements
• Accurate to 0.05% with max resolution of 0.1rpm in either photo or contact mode
• Narrow beam Laser photo tachometer for accurate non-contact RPM measurements
• Measurements from up to 6.5ft from the target for improved safety and accessibility
