RPM40 : Combination Contact/Laser Photo Tachometer ยี่ห้อ Extech, USA

Pocket-Sized Combination Tachometer For Measuring RPM and Linear Surface Speed

The RPM40 is a pocket contact and laser photo tachometer which provides wide RPM (photo/contact) and Linear Surface Speed measurements. Characters on display reverse direction depending on measurement mode used. The narrow beam Laser photo tachometer is for accurate non-contact RPM measurements up to 4.9ft (1.5m) from the target for improved safety and accessibility. Complete with cone tip and wheel for rpm or linear surface speed, four 1.5V AAA batteries and reflective tape.

Features:

Large 5-digit LCD where characters on display reverse direction depending on measurement mode you are in
Microprocessor based with quartz crystal oscillator to maintain high accuracy
Provides wide RPM (photo and contact) and Linear Surface Speed/Length (contact) measurements
Laser guided for greater distance non-contact measurements up to 4.9ft (1.5m)
Memory stores Max/Min/Last readings
Complete with cone tip and wheel for rpm or linear surface speed, four 1.5V AAA batteries, and reflective tape
