HT-6100 Handheld Digital Tachometers From ONO SOKKI

HT-6100, Handheld, Digital, Tachometers, ONO SOKKI

HT-6100 is a handheld tachometer , which the measurement and displaying portion are combined with built-in batteries and is designed to measure the revolution of the gasoline engine and generating rotating objects. Combined with optional detectors such as model IP-292, IP-296, IP-3000A, IP-3100, OM-1200 and TTL signal depending on the measurement objects or purpose, the revolution measurement is possible. The max. 20 measurement data can be stored internally by memory function which is convenient for later checking.

Several measurement items such as revolution (r/min, r/s), accumulated revolution (Counter), period (ms) are available by HT-6100 and both analogue (which can be switched over to monitor also) and pulse output function are provided as standard. Analogue output signal can be used for the recording the signal from data recorder and so on. Monitoring output signal can be used for checking the sensor’s detection waveform or as the input signal by FFT analyzer. Pulse output signal can be used as external clock signal for tracking analysis by FFT analyzer.

Measurement is impossible depending on the model of the engine. Please consult us the nearest distributor when you try the measurement of the engine, which has no record of the measurement in the past

Features

Can be used with various sensors

The HT-6100 can be used with the optional IP-292, IP-296, IP-3000A, IP-3100 and OM-1200 detectors, as well as with TTL signal output detectors.

Three outputs—analog, monitor and pulse—provided as standard

Use the analog output function to record the number of rotations, the monitor output function to check the sensor’s detection waveform, and the pulse output function to output rotation synchronization signals.

Built-in peak hold function

The maximum and minimum values can be displayed during measurement.

Large LCD with backlight

(Character height: 10.2 mm)

Built-in memory function 20 data (MAX) can be saved to memory.

Can be mounted on a tripod

The tachometer can be fixed to a tripod for continuous measurement.
