This manual provides essential information for the proper installation, operation, and maintenance of your ASHCROFT Vacuum Gauge. This test gauge is designed for precise vacuum measurement, featuring a durable construction suitable for industrial applications.
The gauge has a 2-1/2 inch dial, measures vacuum from 30 inches of Mercury (Hg) to 0, and features a 1/4 inch NPT connection located at the lower back. It is constructed with a 304 stainless steel case, 316 stainless steel socket and tube, and a polycarbonate lens. The gauge is filled with glycerin for dampening and enhanced performance.

Always observe standard safety precautions when handling and installing pressure and vacuum gauges. Failure to do so may result in injury or damage to equipment.
- Ensure the system is depressurized before installing or removing the gauge.
- Do not exceed the specified operating range of 30" Hg Vac to 0.
- Verify compatibility of the gauge's wetted parts (316 Stainless Steel) with the process media.
- Protect the gauge from extreme temperatures outside the -40°F to 150°F operating range.
- Handle with care to avoid dropping or impacting the gauge, which can affect accuracy.
3. Eto ati fifi sori
Proper installation is crucial for accurate readings and long service life.
- Igbaradi: Ensure the connection port on your system is clean and free of debris.
- Asopọmọra: The gauge features a 1/4 inch NPT (National Pipe Taper) connection. Apply appropriate thread sealant (e.g., PTFE tape) to the male threads of the gauge connection.
- Iṣagbesori: Carefully thread the gauge into the system's female NPT port. Tighten using a wrench on the wrench flats of the gauge connection. Do not overtighten or apply torque to the gauge case.
- Iṣalaye: The connection location is lower back, allowing for direct mounting or panel mounting with appropriate accessories (not included). Ensure the dial is easily visible for reading.

The ASHCROFT Vacuum Gauge provides accurate vacuum measurements within its specified range.
- Kíkà Ìwé Gíga: The dial is marked from 30" Hg Vac (full vacuum) to 0 (atmospheric pressure). The smallest graduation is 0.5" Hg, allowing for precise readings.
- Yiye: This gauge has an accuracy of +/-1.0% of span, ensuring reliable measurements for test applications.
- Awọn akiyesi iwọn otutu: The gauge is designed to operate effectively within a temperature range of -40°F to 150°F. Operating outside this range may affect accuracy and longevity.
- Glycerin Fill: The glycerin fill dampens pointer pulsation caused by vibration and pressure surges, improving readability and extending the life of the gauge movement.
5. Itọju
Regular maintenance ensures the longevity and accuracy of your vacuum gauge.
- Ninu: Clean the exterior of the gauge, especially the polycarbonate lens, with a soft, damp cloth. Avoid abrasive cleaners or solvents that could damage the lens or case.
- Ayewo: Periodically inspect the gauge for any signs of damage, such as cracks in the lens, dents in the case, or bent pointer. Check the connection for leaks.
- Atunṣe: While designed for long-term accuracy, professional recalibration may be necessary if the gauge is subjected to severe conditions or if accuracy is critical for your application.
- Ibi ipamọ: When not in use, store the gauge in a clean, dry environment within its operating temperature range.

|---|---|---|
| Kika aipe | Gauge exposed to over-vacuum; physical damage; extreme temperature. | Verify operating conditions; inspect for damage; allow gauge to normalize temperature. Consider professional recalibration or replacement. |
| Pointer Fluctuation | System vibration; rapid pressure changes. | The glycerin fill helps dampen this; ensure gauge is securely mounted. If severe, consider a snubber or remote mounting. |
| Leak at Connection | Improperly applied thread sealant; insufficient tightening. | Depressurize system, remove gauge, reapply thread sealant, and re-install, ensuring proper tightening. |
