External sensor input type
Handheld Digital Tachometer
HT-6200
HT-6200 is a handheld tachometer with a built-in batteries designed for measurement of gasoline/diesel engines, EV/HEV motors, and general rotating objects. Combined with optional detectors (VP-202/1220, IP-292/296, IP-3000A, IP-3100, OM-1200/1500, MP-900/9000 series and TTL signal output detector etc.), various rotation measurement are possible depending on the measurement objects or purpose.
Measurement may not be possible or the measurement range may change according to the type of an engine. Please consult your nearest distributor for more details. |
