Waterproof pHep®5 pH Tester and Temperature meter - HI98128

Hanna’s pHep®5 waterproof tester is an advanced pH meter that has many features found in more expensive portable and benchtop meters. This ergonomic meter measures from -2.00 to 16.00 pH with an accuracy of ±0.05 pH. pHep®5 features automatic one or two-point calibration to known buffer, automatic temperature compensation. The large multi level LCD display shows both pH and temperature readings simultaneously, while a stability indicator is displayed to alert the user when a stable reading has been obtained. The pHep®5 tester also features a replaceable pH probe that has a unique extendable cloth junction to clear any clogging that occurs.

Details

The pHep®4 is a waterproof pH tester with a 0.1 pH resolution and an accuracy of ±0.1 pH. It has many advanced features that are found in more expensive portable instrumentation. One or two-point calibration is automatic to two selectable buffer sets (4.01, 7.01 and 10.01 or 4.01, 6.86, and 9.18). The pHep®4 also features a replaceable electrode with a stainless steel round connector. This cartridge design has no pins to line up or that can break. The HI73127 replacement pH electrode also features an extractable cloth junction. The extractable cloth junction of the HI73127 allows for the renewing of the junction. Simply extract ⅛” of the junction by pulling on the junction will expose a new portion. Any clogging that was present will be cleared and the response time will be back to normal extending the life of the pH electrode.
