This is a battery-operated contact handheld tachometer that integrates a rotation detection unit, measurement unit, and display unit.
■ Adopts a curved design that fits comfortably in the hand
■ Wide range from 1.5 to 10,000 r/min
It has two modes: Low mode from 1.5 to 2,000.0 r/min and High mode from 15 to 10,000 r/min. The measurement unit for Low mode is 0.1 r/min, and for High mode, it is 1 r/min.
■ Dual-function type that can also measure peripheral speed
By simply replacing the contact sensor with a disc-shaped peripheral speed ring, you can measure peripheral speed (m/min or mm/s).
■ Pocket for storing the peripheral speed ring
To ensure you can measure peripheral speed at any time, one peripheral speed ring and one rotating contact sensor can be stored in the pocket inside the main unit. When using the peripheral speed ring, two rotating contact sensors can be stored.
■ Data hold function
It automatically holds the final measurement value for about one minute, which is helpful for rechecking the measurement.
■ Battery replacement timing display
To ensure accurate measurements at all times, it displays when the battery needs to be replaced. The "B" sign on the display indicates a low battery.
