ONOSOKKIContact digital handheld tachometerHT-3200This is a high-performance small handheld and contact-handheld digital tachometer that is easy to operate. Just hold it with one hand and gently touch the rotating shaft to get the direct reading of the speed r/min measurement result on the display. In addition, in combination with a peripheral speed ring, it can measure the linear speed m/min or mm/s. The range is large, from low speed 0.5r/min to high speed 10,000r/min, with a resolution of 0.1r/min or 1r/min units, and the speed is measured with high accuracy (circumferential speed range 0.05 to 1000.0 m/min (when using the KS-200 standard peripheral speed ring) or 0.5 to 10,000 mm/s (when using the KS-100 standard peripheral speed ring). The measurement results can be stored in the internal memory as a history, and up to 10 data can be stored, which is convenient for confirmation and recording after measurement. General specifications Speed range Low range: 0.5 to 2000.0 r/min High range: 5 to 10000 r/min Speed measurement unit Low range: 0.1 r/min High range: 1 r/min Circumferential speed range Using KS-100 (option) Low range: 0.5 to 2000.0 mm/s (resolution 0.1 mm/s) High range: 5 to 10000 mm/s (resolution 1 mm/s) Using KS-200 (accessory) Low range: 0.5 to 200.00 m/min (resolution 0.01 m/min) High range: 5 to 10000 mm/s (resolution 0.1 m/min) Number of displayed digits: 5 digits, 7-segment LCD. Measurement display time: 1 second automatic repeat (however, for Low range 1 r/min and High range 10 r/min, 2 seconds automatic repeat) Measurement accuracy: Low range: 0.5 to 1249.9 r/min ± 0.1 r/min, 1250.0 to 2000.0 r/min ± 0.2 r/min, High range: 5 to 10000 r/min ± 1 r/min Memory function: 10 data of measurement results can be stored in non-volatile memory (records can be maintained even when the power is turned off) Data hold function: After measurement, the last measured value is held for 30 seconds, and the power is automatically turned off after 30 seconds. Overrange function: "OVER" is displayed, and BAT is displayed when the measured value exceeds 2000.0 r/min (Lo) or 10000 r/min (Hi). LOW display: "B" is displayed (indicating that the battery is exhausted) Operating temperature range: 0 to +40°C Operating temperature range -10℃ ~ +55℃ Power supply No. 7 batteries (1.5V) × 3, continuous use time about 20 hours Dimensions 172 (W) × 38.5 (H) × 63 (D) mm Weight about 160g (excluding batteries) Accessories KS-300 speed head x 2, KS-200 peripheral speed ring x 1, No. 7 batteries x 3, operating instructions x 1 Optional parts KS-100 peripheral speed ring (unit for peripheral speed measurement mm/s) KS-200 peripheral speed ring (unit for peripheral speed measurement m/min) KS-300 speed head (conical rubber head for speed measurement) KS-700 extension intermediate shaft (for extension of peripheral speed ring or speed head, extension amount 40 mm) HT-0300 carrying case
