VP-3H

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

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

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

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.

BA-2

The double-indicator type vacuum tester allows the measurement of vacuum pressure of two systems at the same time. The use of a meter having two coaxial indicators allows the balance adjustment of two systems by coordinating two indicators, thereby resulting in less reading errors and improving the ease in balance adjustment. The amplitude adjust function allows the adjustment of the shaking width of the indicator even when the indicator shakes so sharply.

VT-2

Integrating two vacuum testers in a compact form, the twin gauge vacuum tester allows the measurement of two systems at the same time.
The amplitude adjust function allows the adjustment of the shaking width of the indicator even when the indicator shakes so sharply.

VT-4B

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

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.

DV-10

This vacuum tester is used for measuring the vacuum pressure of a diesel engine and identifying the cause of an engine failure.
The tester is connected between an engine and governor hose of an injection pump by means of the provided three-way joint.
