Digital Contact Tachometer

Digital Contact Tachometer Description

KEY STRENGTHS: The DT-2236C, allows the safe measurement of rotational speeds, velocities and distances. It measures rpm both optically and mechanically, surface velocities and distances mechanically. Equipped with an automatic display switching from optical to mechanical operation. It allows you to do that accurately and quickly surface speed and length both from a distance using the non-contact mode, rotational speed (RPM) is measured using a visible beam of light and by using the contact operating mode, the speed is sensed by directly contacting rotating device using one of the contact adapters supplied with the instrument. It also has the widest measuring range on the market, providing the from 0.5 to 99,999 RPM. A 5-digit clear digital display shows the exact RPM with no guessing or errors. Its memory function automatically store the last taken maximum and minimum values upon pressing the memory button. Simply stick a little of the supplied reflective tape to a spinning object (works well with gyroscopes). Then point the laser at the spinning object to take a rpm reading and you'll get the result instantly. Applications & Uses: Easy to use and very accurate, the ideal tool for workshops, schools and the tool hire industry. Great tool for measuring the speed of gyroscopes and a "must-have" for laboratory experiments, engineers and technicians. It can also be use in automobiles, trucks, tractors, aircraft, trains and light rail vehicles. FEATURES: This device is very easy to use and have substantial advantages over current technologies.
