Myron L UltrapenX2 PTBT3 Bluetooth ORP / Redox Pen
The Myron L UltrapenX2 PTBT3 reads ORP (redox) and temperature on a 99.9% pure platinum electrode and streams each result to the UltrapenX2 app over Bluetooth. Records are stored with time stamps and optional notes, and the full list exports by email — useful when oxidation potential has to be documented rather than just observed.
Application
ORP is the practical measure of a sanitizer's ability to work, so the PTBT3 fits disinfection monitoring in drinking water and process water, cooling systems, aquaculture and aquarium systems, food and beverage sanitation, and wastewater treatment. Automatic temperature compensation during calibration, a user-replaceable ORP sensor (order RPT3), and a waterproof pen housing that survives the field.
Calibration and care
Calibrate with Myron L 80 mV or 260 mV quinhydrone standards or 470 mV Light's ORP solution; store the sensor in pH/ORP Sensor Storage Solution. ORP electrode cleaning paper (OECP-25 / OECP-100) keeps response fast.
