Testo 470 Digital Tachometer: Optical RPM 1–99,999, Mechanical RPM 1–19,999, Speed 0.01–1999.9 m/min

The Testo 470 is a versatile digital tachometer designed to measure the RPM of rotating objects and speed or length of conveyor belts and rotors. It offers both optical and mechanical measurement capabilities, making it a reliable tool for maintenance technicians, engineers, and facility managers. Compact and easy to operate with one hand, the Testo 470 ensures precise, non-contact RPM readings with an optical sensor and can also measure mechanically using additional adapters.

Key Features:

• Optical RPM Measurement:
  • Record the speed of rotating objects such as motors, fans, and shafts.
  • Measure from a distance of up to 600 mm with a red LED beam.
  • Use reflective markers for precise targeting.
• Mechanical RPM Measurement:
  • Attach the probe tip adapter for direct contact measurements.
  • Measure speeds and lengths with the wheel adapter, ideal for conveyor belts and rotors.
• One-Hand Operation:
  • Compact, ergonomic design for easy operation on the go.
• Clear Display:
  • 5-digit LCD display for easy reading of results.
