pH Testers pH/ORP Combo

A fast, easy way to check your pond's pH Accurate results every time The pHep 4 measures pH and temperature. Thanks to a stability indicator and hold feature, you'll know when to take the reading and you can freeze the display for easy and accurate recording. A stainless steel temperature probe enables fast, precise temperature measurement and auto-compensation. Includes four 1.5V batteries, pH electrode, and electrode replacement tool. pHep 5 provides the same features and convenience, but with more precise readings (?0.01).The NEW pH/ORP Combo measures pH, redox potential, and temperature. The NEW pH/EC/TDS Combo measures pH, conductivity, total dissolved solids, and temperature. Both have ?0.05 accuracy in their readings.All feature automatic temperature compensation. Each also tests temperature (C or F) and includes a protective cap, replaceable electrode, electrode replacement tool, battery level indicator, automatic calibration, data hold feature, four 1.5V batteries, and a battery error prevention system. Each measures 1-3/4" x 6-3/4" x 3/4" thick.Please note: While testers are automatically calibrated by the manufacturer, unavoidable jarring during shipping may affect calibration. Therefore, you should re-calibrate your tester using a Calibration Solution (sold below) prior to initial use.When not in use, rinse the electrode with water to minimize contamination and store it with a few drops of Storage Solution (sold separately) in the protective cap.Please click on "More Information" for specifications.
