เครื่องวัดความเร็วรอบ 2 แบบ ในตัวเดียวกัน
Tachometers are used for counting the revolutions of an engine per minute, and this multi-function digital tachometer allows you to do that accurately and quickly both from a distance by using the laser, or, if you prefer, by using the contact function and attachments.
Unlike some lesser models on the market, this tachometer has a fantastic, wide measuring range of 0.5 to 99,999 RPM.
An advanced one chip microcomputer LSI-circuit and crystal time base provide consistently highly-accurate readings in the fastest time possible.
The clear digital display shows the exact RPM with no guessing and no errors whilst the memory function will store the last taken maximum and minimum values at the press of a button.
The ergonomically designed casing fits comfortably in either hand and is made from ultra light, yet durable plastic, protecting the delicate internal workings and ensuring maintenance free performance for years to come.
