Handheld Revolution Meter for Contact and Non-Contact Revolution Measurement

The portable handheld revolution meter is used to perform optical or mechanical speed measurements. This portable digital handheld revolution meter is ideal for establishing the revolutions of rotating machines, parts, and installations (e.g., in conveyor belts, in motors and belt-driven mechanisms...). Non-contact measurement is performed with the help of a reflective band that adheres to the rotating part; contact measurement is carried out by means of a mechanical adapter with a head or a measuring wheel included in the shipment (see photo). The handheld revolution meter has a switch for range selection and memory for MAX and MIN values. It is delivered ready for use (the case includes measuring wheels and battery).

• Optical non-contact measurement with the reflective bands included
• Contact measurement in rpm with conical adapter (for ends of shafts or center drills in motors and mechanisms)
• Contact measurement in m/min with wheel
• Solid ABS plastic housing
• The 10 mm LCD screen and 5 positions of the handheld tachometer automatically rotates 180° depending on whether the measurement is taken with or without contact
• Memory for last value, MIN / MAX values
• Interchangeable measurement adapters (also available as spare parts)

Measurement Ranges

Speed Measurement Ranges

• 5 ... 99999 rpm (optical measurement)
• 0.5 ... 19999 rpm (contact measurement)
• 0.05 ... 1999 m/min (contact measurement)
• 0.2 ... 6560 ft/min (contact measurement)

Resolution

Resolution

• 0.5 ... 999.9 = 0.1 rpm; up to 99999 = 1.0 rpm (optical measurement)
• 0.5 ... 999.9 = 0.1 rpm; up to 19.999 = 1.0 rpm (contact measurement)
• 0.05 ... 99.99 = 0.01 m/min; up to 1999 = 0.1m/min (contact measurement)
• 0.2 ... 999.9 = 0.1 ft/min; up to 6560 = 1 ft/min (contact measurement)
