Myron L PoolPro PS9 Pool & Spa Meter with Alkalinity, Hardness & LSI Titration

The Myron L PoolPro PS9 is the Ultrameter III platform tuned for pool and spa service: conductivity, TDS, salt concentration, pH, ORP, Free Chlorine Equivalent, alkalinity, hardness, temperature and a Langelier Saturation Index calculator in one waterproof handheld. In-cell conductometric titrations give you alkalinity and hardness on the deck, and the LSI calculator lets you test a dosing decision before you make it. Application Built for route technicians and aquatic facility staff managing scale, corrosion and sanitizer effectiveness across pools, spas and salt (electrolysis) systems. FCE reports free available chlorine from ORP cross-referenced with pH — the chemistry of the source water itself, not a diluted test-tube sample. ±1% of reading accuracy, IP67 / NEMA 6 waterproof and buoyant to 3 ft (1 m), 100-reading memory with date/time stamp. Model options PS9 — instrument only PS9-BD — bluDock enabled for wireless transfer to a PC PS9TKB — titration kit in a foam-lined hard case with reagents, standards, cell extender, plunger and pipette PS9TKB-BD — titration kit with bluDock installed Documentation PoolPro Data Sheet (PDF) PS9 Operation Manual (PDF) PS9 Quick Start Guide (PDF) Replacement sensors, reagents, calibration solutions and cases: see our Myron L Parts & Accessories collection.
