Triple set of hydraulic gauges (for low and high pressure) |
The triple set of hydraulic gauges including gauges allowing the measurement of low pressure through high pressure can be used for extensive applications.
| Meter diameter | Max. scale | Min. scale | Overall length | Accessories | Case | Total weight |
| φ60mm | 2.5MPa （Approx.25kgf/c㎡） | 0.1MPa | 1,470mm | Nipple (for low pressure) PT1/8、PT1/4 (1 for each) | Metal case W370× D270× H65mm | Approx. 4,600g |
| φ75mm | 7MPa （Approx.70kgf/c㎡） | 0.2MPa | 1,630mm | Nipple (for high pressure) PT1/8、PT1/4、PT3/8 (2 for each) |
||
| φ75mm | 35MPa （Approx.350kgf/c㎡） | 1MPa | 1,580mm |
- ● A variety of optional adapters are also available.
 Note for selecting a hydraulic gauge | In selecting a hydraulic gauge, use caution so that pressure to be measured does not exceed the maximum
scale of the meter.
The use of the gauge for measuring exceeding the maximum scale may result in an accident causing damage to the gauge and rupture of the hose. |

Throttle device for hydraulic gauge (Buffer screw 1/4, 3/8, 1/2)
If the pulsation of pressure to be measured is extremely large, the indicator
of the pressure gauge is extremely shaken, which may result in failure of
the gauge.
In this case, use the throttle device by connecting it to the hydraulic gauge
so as to reduce the shaking of the indicator, which makes it possible to read
indicator with ease and to prolong the life of the gauge.
