Extech RPM33
Combination Contact/Laser Photo Tachometer
The Extech RPM33 provides both contact (2 to 19,999 rpm) and non-contact (2 to 99,999 rpm) revolutions per minute measurements for enhanced versatility. Safely record laser-guided non-contact RPM measurements from up to 500 mm (1.6 feet) away. The RPM33 displays on the large five-digit backlit LCD. Store and recall 10 data sets in memory with four parameters (measurement, max, min and average). The unit comes with contact wheel for linear surface speed 0 to 1999.9 meters/minute; 0.2 to 6560 feet/minute) or RPM measurements, 9-volt battery, reflective tape, carrying case, and user manual.
