Pool Link 500 Series Probe Chamber - 4 Probe

The Pool Link 500 Series Probe Chamber - 4 Probe is an expanded, commercial-grade bypass flow cell manifold engineered to house four analytical sensors simultaneously. Plumbed into an auxiliary bypass line across the main pool recirculation loop, it provides a stable, low-turbulence sampling environment for complex commercial aquatic systems—typically accommodating combination pH, platinum-band ORP, temperature, and either an amperometric Free Available Chlorine (FAC) or nephelometric turbidity sensor in a single, compact acrylic block.

System Overview & Hardware Architecture

Designed for high-bather-load commercial facilities, competition aquatic centers, and municipal water venues requiring comprehensive water chemistry and clarity monitoring:

• Clear Machined Acrylic Solid-Block Body: Precision-machined from a single block of heavy cast acrylic. The optical-grade clarity permits direct visual inspection of internal flow conditions, air bubble entrapment, and probe membrane fouling across all four sensing wells without system depressurization.

• Four-Port In-Line Chamber Design: Positions four analytical probes in a continuous hydraulic sequence optimized to deliver equal sample exchange rates while isolating sensor junctions to prevent chemical cross-contamination or electrical signal cross-talk.

• Inlet Flow-Regulating Needle Valve: Fine-threaded, chemical-resistant metering valve located at the sample intake to throttle line pressure and maintain stable, laminar flow across fragile sensing tips, preventing cavitation and velocity impingement.

• Manual Calibration Petcock: Integrated low-pressure sample valve positioned adjacent to the probe chambers, allowing operators to draw representative pool water for routine photometer, DPD colorimetric, or titrimetric verification tests.

• Rigid Backboard Mounting: Rear drilled and tapped mounting holes facilitate direct attachment to an equipment backboard, Unistrut channel, or equipment room wall.

Technical Specifications

• Port Configuration:

  • Four 1/2" NPT or 3/4" NPT threaded or compression gland ports compatible with commercial glass pH, platinum ORP, solid-state temperature, and amperometric/turbidity probe bodies.

  • Captive compression collars with chemical-resistant Viton or EPDM O-rings for pressure-tight sealing.

• Hydraulic Operating Limits:

  • Maximum Working Pressure: 50 PSI (approx. 3.45 bar).

  • Optimal Bypass Flow Rate: 0.5 to 1.5 GPM (approx. 1.9 to 5.7 LPM).

  • Operating Water Temperature: 32°F to 120°F (0°C to 49°C).

• Plumbing Connections: Standard 1/4" NPT female inlet and outlet ports, pre-fitted with 3/8" OD compression adapters for semi-rigid polyethylene sample tubing.
