This professional tachometer (digital rotary measuring instrument) from RS PRO offers the latest technologies in a robust and durable housing and allows for fast and accurate measurements of rotational speeds via a precise beam of light together with reflective tape. It features an integrated optical transmitter and receiver at the top of the unit and the 5-digit LCD that displays direct RPM measurements and is equipped with a memory function. It can be used to measure max., min., and average values of rotations. The ergonomically designed body makes it a comfortable device to use at any location. The Optical Tachometer is a must-have device for any operator working in close distance to high-risk machines or where the access is restricted.

• Detecting distance from 0.25m up to 1m
• Measures max., min., and average values in both metric and imperial units
• Microprocessor based circuit, crystal time base, high precision with 0.05% accuracy
• Wide measuring range from 5 to 99999 RPM
• Clear and easy to read 5-digit LCD display with a memory function
• Direct RPM reading function
• Supplied with a durable carrying case
• Calibration Certificate
• 3 Years warranty

This tool is just as important in the implementation and day to day operations of machinery and systems as it is for maintenance and would also benefit research and development laboratories. Tachometers are typically used for measuring e.g:

• The speed of rotating equipment such as motors, turbines, fans, wheel, shafts, rollers
• Travelling speed of belts and conveyors
• Length of long products such as wire, fibre, steel, wood, etc.
• The speed of travel and length of sheet products such a films and foils

Is this tachometer supplied with a battery?

No, the tachometer is not supplied with batteries. It requires 4 x AA batteries e.g. 7442199

How does an optical sensor work?

The tachometer's optical sensor uses a beam of laser light to measure the speed of rotation of the wheel or shaft. It measures differences in frequency of the reflected light.

What do I get in a set?

The Tachometer is supplied with:
• Carrying Case
• Reflective Tape Marks
• Manual
