Model : Ono sokki HT-4200
The HT-4200 is a compact, non-contact type handheld digital tachometer. Affix one of the reflective marks to the rotating surface of the target measurement object, and then aim the red visible ray at the mark. If multiple marks are affixed to the target of measurement object, measurement can be performed at a lower speed.

Specifications

Detection method

Red visible ray photoelectric reflection method

Detection distance

20 to 300 mm

Display

5-digit LCD (10.5-mm character height), fixed measurement unit (r/min)

Measurement update time

1-s automatic update (2-s update when the circumferential speed is lower than 60/number of reflective marks r/min)

Measurement range

Measurement resolution: 1 r/min

The affixing of multiple reflective marks enables measurement of lower rotation speeds.

Measurement speed	Number of reflective marks
30 to 50,000 r/min	1
15 to 25,000 r/min	2
10 to 16,667 r/min	3
8 to 12,500 r/min	4
5 to 8,333 r/min	6
4 to 6,250 r/min	8

Measurement accuracy (when one reflective mark is used)

30 to 12,499 r/min speeds : Within ±1 r/min
12,500 to 24,999 r/min speeds : Within ±2 r/min
25,000 to 50,000 r/min speeds : Within ±4 r/min

Measurement of the number of pulses

The number of reflective marks used can be specified in order to perform measurement from lower rotation speeds. Specifiable values: 1, 2, 3, 4, 6, 8 P/R

Memory function

10 data can be memorized.

Data hold function

Auto power off when 30 seconds have elapsed after the end of measurement.

Low battery indication

The “LOW” mark is displayed when the battery voltage falls below 3.3 V.

Over-range display

An “ERROR” mark is displayed.

Power source

Three AAA-type batteries (1.5 V), Continuous measurement time: Approx. 20 hours (when alkaline batteries are used, at 20°C)

Operating temperature

0 to +40°C
