HT-3200
High Accuracy Contact Type Tachometer

The HT-3200 offers a Low measurement range that starts from 0.5 r/min.
The circumferential ring and contact tip for rotation measurement can be stored in the back-side pocket of the main body.

FEATURES

Capable of measurement from a low speed at 0.5 r/min (when low range selection) up to a high speed at 10,000 r/min (when high range selection).

A large-size display device (10.5-mm character height) is incorporated into the compact, lightweight device.

Built-in convenient memory function for easy confirmation of the measured results

Dual-purpose type—replacing the contact tip with the circumferential ring enables circumferential measurement

Equipped with a storage pocket for the circumferential ring

The latest measurement value continues to be displayed for approximately 30 seconds even after the power has been switched off.

Battery replacement time indicator is provided.

HT-4200
Non-Contact type Tachometer
Slip in your shirt pocket tachometer

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.

FEATURES

The 5-digit display enables wide-ranging measurement from 4 r/min (when multiple reflective marks are used.) to 50,000 r/min (when single reflective mark is used.)

A large-size display device (10.5-mm character height) is incorporated into the compact, lightweight device which can be easily slipped into your shirt pocket.

Built-in convenient memory function for easy confirmation of the measured results

Even shiny shafts can be measured by using the reflective marks provided with the device.

Measurement can be performed over a wide range from 30 r/min to 50,000 r/min, in 1-r/min resolution (when one reflective mark is used).

Measurement can be performed safely at a distance ranging from 20 to 300 mm between the detection unit and the target measurement surface (the reflective mark surface).

The latest measurement value continues to be displayed for approximately 30 seconds even after the power has been switched off.

Battery replacement time indicator is provided.

SPECIFICATIONS

Detection Method : Red visible ray photoelectric reflection method

Detection Distance : 20 to 300mm

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.

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 speed Within ±1 r/min
12,500 to 24,999 r/min speed Within ±2 r/min
25,000 to 50,000 r/min speed Within ±4 r/min
