Overview
The Noshok 0-3000 PSI pressure gauge is a liquid-filled dial indicator designed for demanding industrial, hydraulic, and mobile equipment applications. Available with dual-scale markings (0-3000 PSI / 0-20000 kPa), this gauge combines robust construction with accuracy to monitor system pressures reliably. Polished brass cover ring, acrylic lens with o-ring seal, and brass and nickel-silver movement ensure long service life in harsh operating conditions.
Key Features
- Glycerin-filled design reduces vibration and needle flutter for stable readings
- 1% full-scale accuracy for precise pressure monitoring
- Copper alloy or 316 stainless steel and brass wetted parts resist corrosion
- Impact-resistant ABS and stainless steel case provides durability
- Dual-scale display (PSI/kPa) simplifies metric and imperial readings
- 1/4″ NPT threaded male bottom-side process connection for standard industrial mounting
