EXTECH RPM33 : Combination Contact/Laser Photo Tachometer ยี่ห้อ Extech, USA

Quickly measure RPM, surface speed and length with one tool

The RPM33 provides both contact (2 to 19,999 rpm) and non-contact (2 to 99,999 rpm) RPM measurements for enhanced versatility. Laser guided non-contact RPM measurements taken up to 1.6-foot (500mm) away for added safety. Readings are displayed on the large five-digit backlit LCD. Store/recall 10 data sets in memory with 4 parameters (measurement, max, min and average). Comes with contact wheel for linear surface speed (0.2 to 6560 feet/minute; 0 to 1999.9 meters/minute) or RPM measurements, 9-volt battery, reflective tape, carrying case, and user manual.
