Applications of the hydraulic pressure gauge
• Intended for severe service conditions where pulsation or vibration exist
• Suitable for all gaseous and liquid media that will not obstruct the pressure system or attack copper alloy wetted parts
• Hydraulic systems and compressors
Product features of the hydraulic pressure gauge
• Vibration and shock resistant
• Compound pressure ranges to 200 PSI (16 bar)
• Ranges up to 6,000 psi (400 bar)
• Reliable and economical
