A low cost Mini LCD Digital Tach/Hourmeter with
a variety of uses, keeps track
of true engine running RPM and time for all types of gasoline
engines. The unit
is powered by an internal lithium battery. No external power
connections are required.
The operation of the Tach/Hourmeter is triggered
by an external lead, wrapped around the spark plug wire of the engine.
Since the unit is triggered
by the spark of the engine, the hours and the RPM display actual
operation. This is useful for maintenance and warranty applications
for any type
of engine-powered machinery.
With solid state technology the Mini Tach is built with a custom chip
and diebonding construction for maximum durability for harsh environments
and rugged application.
When the engine is on, the display will read
the RPM of the engine. When the engine is off, the display will
switch to runtime and remains visible.
