Pool Link 500 Series Probe Chamber - 2 Probe

The Pool Link 500 Series Probe Chamber - 2 Probe is a compact, commercial-grade bypass flow cell manifold engineered specifically to house two analytical electrodes (typically combination pH and platinum ORP probes). Plumbed in an auxiliary loop across the primary pool recirculation line, it isolates delicate sensing tips from pipe turbulence, maintains stable hydraulic sampling conditions, and provides essential physical protection and manual sampling access for commercial aquatic facilities.

System Overview & Hardware Architecture

Engineered for municipal natatoriums, commercial spas, water features, and hotel pools requiring a streamlined, dedicated two-sensor monitoring station:

• Clear Machined Acrylic Solid-Block Body: Precision-bored from high-clarity, chemical-resistant cast acrylic. The monolithic transparent design allows operators to immediately inspect the sampling chamber for air bubble entrapment, probe tip bio-fouling, and mineral scaling without disrupting line pressure.

• Dual-Port Probe Layout: Optimized strictly for two standard analytical sensors (such as pH and ORP), reducing internal dead volume and ensuring high turnover rates across the electrode membranes.

• Integrated Needle Flow Control Valve: Fine-threaded, chemical-resistant metering valve located at the sample stream inlet, allowing precise adjustment of water velocity to prevent sensor tip impingement and cavitation.

• Manual Sample Draw Petcock: Integrated low-pressure sampling valve positioned adjacent to the electrode tips, enabling operators to draw representative pool water for photometer or DPD titrimetric calibration testing.

• Mounting Backplane Compatibility: Engineered with rear threaded mounting holes for direct attachment to equipment room backboards, equipment struts, or wall panels.

Technical Specifications

• Port Configuration:

  • Two 1/2" NPT or 3/4" NPT threaded/compression gland ports accommodating standard commercial glass pH and platinum-band ORP electrodes.

  • Captive compression collars with Viton or EPDM O-ring seals for pressure-tight retention.

• Hydraulic Limits & Operating Parameters:

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

  • Optimal Operating 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, typically fitted with 3/8" OD compression tube adapters for semi-rigid polyethylene bypass lines.
