It dramatically cuts down on manual water testing and corrective dosing, and helps prevent skin irritation and red eyes while protecting your pool equipment.\u003c\/p\u003e\u003cp\u003eChoose the AC1 for full pH and ORP (chlorine) control, or the AC1-pH for pH control only.\u003c\/p\u003e\u003ch2\u003e📦 Parts Included\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e1x SmartChem expansion unit with peristaltic pump and squeeze tube\u003c\/li\u003e\n\u003cli\u003e1x pH sensor, plus 1x ORP sensor (AC1 only)\u003c\/li\u003e\n\u003cli\u003e1x Sensor manifold and 1x dosing manifold for 50 mm pipe, with 40 mm reducing bushes\u003c\/li\u003e\n\u003cli\u003e1x Power cable and communication cable\u003c\/li\u003e\n\u003cli\u003e5 m acid dosing tube, 5 m acid tubing and an acid tube check valve\u003c\/li\u003e\n\u003cli\u003e1x Acid drum connecting kit (lids, pick-up tube, breather connector)\u003c\/li\u003e\n\u003cli\u003eManifold blanking caps and a pH probe cleaning tool\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003e⚙️ Specifications \u0026amp; Compatibility\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSKU:\u003c\/strong\u003e AC1 (pH \u0026amp; ORP) \/ AC1-pH (pH only)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003epH reading range:\u003c\/strong\u003e 5.5–8.5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eORP reading range:\u003c\/strong\u003e 300–800 mV (AC1)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDosing:\u003c\/strong\u003e peristaltic pump, diluted hydrochloric acid\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePipe size:\u003c\/strong\u003e manifolds suit 50 mm pipe, with 40 mm reducing bushes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRequires:\u003c\/strong\u003e Oasis Smart master controller (OSC001) and a chlorinator plugged into the Oasis Smart\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApp:\u003c\/strong\u003e readings update in the Oasis Smart app every 30 minutes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003e💡 Before You Buy\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOasis Smart required.\u003c\/strong\u003e SmartChem connects to the \u003ca href=\"\/collections\/pool-automation\"\u003eOasis Smart Pool and Spa Wi-Fi Control System\u003c\/a\u003e and needs a free actuator port on it.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWater balance first.\u003c\/strong\u003e The system works best with free chlorine 1–3 ppm, pH 7.2–7.8, total alkalinity 80–150, calcium hardness 150–300 ppm, zero phosphate and low stabiliser (0–15 ppm).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOngoing maintenance.\u003c\/strong\u003e Replace the squeeze tube every 12 months and clean the probes every 6 months.
