senctrl Pool Filter Pressure Gauge 0-60 psi 1/4 NPT Back-Mount, IP67 304 Stainless

This pressure gauge is designed for routine monitoring of pool and spa filtration systems, offering a clear dial, a simple "clean filter" indicator, and a 1/4" NPT back-mounted connection for straightforward installation. It combines corrosion-resistant materials with a waterproof enclosure to maintain reliable readings in humid or wet environments commonly found around pools, spas and outdoor equipment.

How will this gauge help me spot a clogged pool filter?

The gauge includes a rotatable clean-filter marker that you set when the system is clean; as pressure rises it shows when pressure has moved into the “clean filter” vs. “start” zones so you can tell when backwashing or cleaning is needed. The dial’s dual scale also helps you compare pressure at different times or against manufacturer recommendations.

• Rotating indicator with clear "Start" and "Clean Filter" markings for quick reference.
• 0–60 psi scale (also 0–4 bar) to match common pool system requirements.
• Accuracy within approximately ±3% across the full range for consistent trending.

What makes this gauge suitable for wet or outdoor pool environments?

The circular dial sits inside a 304 stainless steel case and carries an IP67 rating, limiting moisture ingress and reducing dial fogging from condensation. Wetted parts that contact the measured fluid are brass and stainless steel, chosen for compatibility with non-corrosive liquids like fresh water in pools and spas.

• 304 stainless steel casing resists corrosion and outdoor wear.
• IP67 waterproofing helps keep the internal window clear and functioning.
• Brass and stainless wetted parts for durable contact with pool water and similar fluids.

How do I install and read this back-mount gauge?

Installation uses the standard 1/4" NPT male back connection; thread into a compatible port on filter housings, pumps or pressure test ports. Read the dial using the two scales—psi and bar—and use the clean-filter pointer to mark baseline pressure after a clean backwash.

• 1/4" NPT back-mount male thread for compact, concealed mounting options.
• Dual-scale face shows both psi and bar values for easy conversion.
• Simple mechanical pointer and indicator require no power to operate.

What accuracy and range should I expect from this gauge?

The gauge covers a practical service range for pool filters from 0 up to 60 psi and provides display accuracy around ±3% of the indicated value across its span, adequate for routine maintenance checks and system monitoring.

• Range: 0–60 psi (0–4 bar) to suit typical residential pool and spa systems.
• Display accuracy specified at roughly ±3% across the full scale.
• Mechanical construction avoids electronic failure modes in damp settings.

Who is this for: The SENCTRL 0–60 Psi Pool Filter Pressure Gauge is aimed at pool and spa owners, service technicians, and maintenance professionals who need a durable, clear-reading, back-mounted pressure instrument. It fits systems that accept a 1/4" NPT back connection and is useful wherever corrosion-resistant materials and waterproofing improve long-term reliability around water features and outdoor equipment.
