Pool & Spa Controllers (ORP/pH & Automation)

Automate perfect water balance. This collection features professional pool and spa controllers that continuously monitor and control ORP (sanitizer) and pH, with options for free-chlorine (ppm) sensing, temperature, TDS/conductivity, and equipment interlocks. Pair a controller with chemical feed (peristaltic pumps, erosion feeders, CO₂/acid systems) to keep water safe, stable, and consistent—residential or commercial.

What to look for:

• Measured parameters: ORP & pH standard; optional ppm free chlorine, temperature, TDS/conductivity, flow/level.

• Control method: On/Off, proportional, or PID output; adjustable setpoints, dose limits, safety timeouts.

• Outputs & integration: Relay outputs for acid/bleach pumps or valves; dry contacts for interlocks; some models support remote monitoring/logging.

• Sensors & plumbing: ORP (gold/platinum), pH probes, flow cells/bypass tees, sample lines, calibration solutions.

• Chemistry & sizing: Match to sanitizer (liquid chlorine, bromine, salt) and pool volume/turnover; confirm material compatibility.

• Environment: Indoor/outdoor enclosure ratings; panel or wall mount; line voltage vs. low-voltage control.
