The PS9 is a quick and easy way to stay on top of Total Dissolved Solids (TDS) which profoundly impacts water taste and bather comfort. In a commercial pool or spa you must carefully monitor and control TDS on a regular basis to maintain acceptable levels. PS9 measures and reports temperature to one tenth of a degree with every sample taken. Temperature plays a role in water balance, the growth of microorganisms, and especially affects bather comfort. PS9 Meters provide the fastest, most precise, easy-to-use method of obtaining Oxidation Reduction Potential (ORP or REDOX) readings to check the true level of effectiveness of all sanitizers in any pool or spa. These meters conveniently test For mineral/salt concentration at the press of a button.
