Japanese ASK Pressure Gauge AVT-R1/4-60X-0.1MPa-GR0.015GR Vacuum Gauge

Model Explanation

• AVT: Radial mounting, vibration-resistant type with square mounting flats;

• R1/4: Connection thread: R1/4 British tapered pipe thread;

• 60: Dial diameter: 60 mm;

• -0.1MPa: Measuring range: 0 ~ -0.1 MPa (near absolute vacuum value).

Core Specifications & Features

• Brand & Origin: Made in Japan by ASK Co., Ltd.;

• Measuring principle: Bourdon tube mechanical pointer type, displayed in MPa;

• Vibration-resistant structure: Normally glycerin-filled to effectively suppress pointer fluttering, suitable for vibrating conditions of hydraulic/pneumatic equipment;

• Connection & mounting: Radial R1/4 (equivalent to PT1/4) 55° British pipe thread, can be directly screwed into pipelines or mounted on brackets;

• Applicable media: Gas / clean liquids, commonly used in vacuum systems, vacuum pumps, refrigeration equipment, etc.;

• Operating temperature: Generally -5℃ ~ 40℃; sealed liquid filling protects internal parts against corrosion and provides lubrication.

Selection & Usage Notes

• This gauge has a measuring range of -0.1 MPa ~ 0, for negative pressure (vacuum) only; not suitable for systems with high positive pressure.

• Its accuracy and damping design are suitable for vacuum conditions requiring stable readings; avoid use in over-range or highly corrosive media.

• Install vertically, avoid shock and severe vibration; calibrate regularly to ensure measurement accuracy.
