B"H This liquid filled pressure gauge measures pressure from 0-1000 PSI. Ideal for hydraulic or pneumatic systems, compressors, pressure washers, and other fluid power applications. The 0-1000 PSI range is commonly found on hydraulic presses, industrial clamping fixtures, and heavy-duty pressure washers that demand accurate readings at elevated pressures. Liquid filling dampens needle vibration for stable, accurate readings in high-pulsation environments.
