INSIZE - Digital Tachometer (Non Contact Type) (50 - 99999RPM) (9221-999 ) + FREE CALIBRATION CERTIFICATE

A non-contact digital tachometer from INSIZE used to measure rotational speed (RPM) of shafts, pulleys, motors, fans, and other rotating machinery without touching the surface. It uses a laser/optical method with a reflection sticker on the target, providing fast, accurate speed readings for workshop, maintenance, and inspection tasks.

KEY FEATURES:
• Measuring range: ~2.5 – 99,999 RPM (varies slightly by model)
• Resolution: 0.1 RPM at low speed and up to 1 RPM at high speed
• Accuracy: ±(0.05 % n + 1 digit) approx. (n = measured RPM)
• Laser class: Class 3R visible laser for non-contact measurement
• Display: Digital LCD with max/min/last value hold functions
• Memory: Stores measured values (max/min/last)
• Measuring distance: approx. 50 – 500 mm (varies)
• Automatic power-off to save battery
• Power: AAA batteries (typically 2–3)

APPLICATIONS:
• Measuring rotational speed (RPM) of motors, pulleys, fans, and spindles
• Machine setup and maintenance in factories and workshops
• Preventive maintenance and vibration analysis
• Quality checks on rotating components
• Speed verification during production and testing
