Vacuum tester
VP-3H |
Handy vacuum pump |
The handy vacuum pump allows generating vacuum pressure by
manual operation.
Since the handy vacuum pump allows pressure reduction as
desired, it is indispensable for maintaining a device operated by
vacuum pressure

VG-7B |
Vacuum tester (With amplitude adjust function) |
This vacuum tester is used for identifying the cause of engine
failure by measuring the negative pressure in the intake manifold of
a qasoline engine car.
Being provided with the amplitude adjust function, the shaking width
of the indicator can be adjusted according to need when the
indicator shakes so sharply as to make reading difficult.

VG-8 |
Vacuum tester (Precision class) |
This vacuum tester is used for identifying the cause of engine
failure by measuring the negative pressure in the intake manifold of
a gasoline engine car.
The use of large-sized negative pressure gauge with smaller
minimum scale enables minute adjustments.

VF-3B |
Vacuum fuel pump tester (With amplitude adjust function) |
This vacuum fuel pump tester is provided with two functions of both
a vacuum tester and a fuel pump tester.
Since the tester is provided with amplitude adjust function. the
shaking width of the indicator can be adjusted when indicator
shakes so sharply in vacuum testing.
Measurement is allowed up to 50kPa (approx. 0.5kgf/c㎡) for fuel
pump testing.

VT-4B |
Four gauge vacuum tester (With amplitude adjust function) |
The four gauge vacuum tester allows the measurement of up to four
systems at the same time, and makes it easy to make measurement and
balance adjustment of a multi-cylinder engine.
Being provided with an adapter for a two-wheeled vehicle. this tester is
indispensable for maintaining a two-wheeled vehicle.
Since each tester can be used separately on its own, it can be used for
extensive applications ranging from a single cylinder engine to four
cylinder engine.
The amplitude adjust function allows the adjustment of the shaking width of
the indicator even when the indicator shakes so sharply.

TB-3-1･TB-3-2 |
Compound gauge |
This compound gauge allows the continuous measurements of pressure
ranging from positive pressure to negative pressure, thereby enabling the
measurement of vacuum pressure and boost pressure of an engine with a
supercharger.
Since the use of the provided pump bulb allows the manual application of
pressure as desired, this gauge allows testing and making adjustment of a
device operated at positive pressure with ease.
Two types of gauges for the measurement of positive pressure are available
in 100kPa (approx. 1kg/c㎡) and 200kPa (approx. 2kg/c㎡) types.
