Prescale functions (Except TC-4L)
Based on a preset scale, the tachometer converts the number of revolutions to a distance, volume or production per unit time. The prescale function is not included in the TC-4L model.
High accuracy
The cycle measurement is used in measurement format to obtain a high degree of precision at low speeds. Using a sampling technique, the tachometer ensures ample precision even at high speeds.

Products Specification

Prescale functions (Except TC-4L)
The TC-4 series features built-in prescale functions that can convert the number of revolutions into speed, flow rate, and the amount of production per unit time.
High accuracy
Owing to the period measurement method, the TC-4 series offers high measurement accuracy in low speed rotation. The sampling function guarantees sufficient accuracy even in high speed rotation.
Immediate zero display when rotation stops (TC-41)
The display becomes zero 1 or 6 seconds after rotation stops.
