Myron L UltrapenX2 PTBT4 Bluetooth Free Chlorine Equivalent (FCE) Pen
The Myron L UltrapenX2 PTBT4 reports Free Chlorine Equivalent — free available chlorine derived from ORP and pH — with no reagents, no color matching and no dilution, then logs each reading to the UltrapenX2 app over Bluetooth with a time stamp and optional note.
Application
Because FCE is calculated from the oxidation potential of the source water itself, it reflects actual disinfection power rather than the chemistry of a sample in a test tube. That makes the PTBT4 well suited to drinking water distribution, well and booster station checks, cooling water disinfection, food processing sanitation, and pool and spa service where a documented chlorine record is required. Waterproof pen housing, automatic temperature compensation, user-replaceable sensor (order RPT4).
