The pHep®4 and pHep®5 are waterproof pH testers that have many advanced features found in more expensive portable
instrumentation. These ergonomic meters feature automatic one or two point calibration to a known bu*er, automatic
temperature compensation, battery percent level indicator at start up, and a stability indicator to alert the user when
a stable reading has been obtained. The large multi level LCD display shows both pH and temperature simultaneously.
