Contact and non-contact dual-use digital handheld tachometer
HT-5500
This is an advanced handheld tachometer that combines rotational measurement technology, fully equipped with functions in a refined body, easy to use for both contact and non-contact types, and high performance.
The measurement items include rotational speed (r/min, r/s), cumulative rotation count (count), peripheral speed (m/min, contact, non-contact), (mm/s, contact type), period (ms), and multiple items. It comes standard with both analog output and pulse output; the analog output can be used for recording with data recorders, while the pulse output can be used as a signal for tracking analysis with an FFT analyzer.
This is a wide-range, high-function handheld tachometer capable of measuring from low speed (6.0 r/min) to high speed (99,999 r/min).
*Please prepare batteries by yourself.

| reflection detection distance | 20 to 300 mm | |||||||||||||||||||||
| Display Section | LCD display, 5 digits, with backlight (character height: 10.2 mm) | |||||||||||||||||||||
| measurement time | Within 1 second plus 1 cycle time (however, for speeds below 60 r/min, the maximum cycle time is about twice that). | |||||||||||||||||||||
| Display update time | about 1 second | |||||||||||||||||||||
| measurement accuracy | Display value (* ) × (±0.02 %) ±1 count * The display value is the count value excluding the decimal point (Note) The measurement accuracy of the peripheral speed depends on the rotational speed of the rotating body. The above measurement accuracy is for non-contact measurement. Additionally, errors due to hand shake are not included. In contact measurement, slippage of the contact point and accuracy are added. |
