Rechargeable, USB-Compatible, Indispensable Device Handles a Variety of Tasks

Test pH, ORP and temperature accurately and easily with these pH Meters. Calibration Check™ compares the pH electrode state to the previous calibration and warns you if there are significant changes. This feature helps you avoid erroneous calibration due to a bad or dirty electrode or a contaminated buffer solution. Rechargeable batteries give you up to 200 hours of use and recharge in just hours with the unique inductive charger, which plugs into a standard 115V AC outlet or any vehicle’s 12V DC accessory outlet.

Each pH Meter includes a pH electrode, temperature probe, pH 4.01 and pH 7.01 buffer solutions, four AA rechargeable batteries, inductive battery charger with power adaptor, carrying case and instructions. Optional Windows® Software allows you to sort or filter all collected data using different criteria, such as sampling location, parameter, date/time intervals and more. Data can be plotted in a graph, exported to other programs or printed.
