The tester Hanna pHep®4 is a tool equipped with advanced features typically found in more expensive bench and portable instruments. This ergonomic measuring device measures from -2.0 to 16.0 pH with an accuracy of ± 0.1 pH. pHep®4 is equipped with automatic calibration at one or two points and automatic temperature compensation. The large screen simultaneously displays pH and temperature measurements, while a stability indicator alerts the user when the measurement is stable. pHep®4 also features a replaceable pH probe that uses a removable fiber junction to eliminate any blockage.
pHep® 4 is a waterproof pH tester with a resolution of 0.1 pH and an accuracy of ± 0.1 pH. It is packed with several advanced features found in more expensive portable instruments. The one or two-point calibration is automatic using two sets of standard solutions (4.01, 7.01, and 10.01, or 4.01, 6.86, and 9.18). pHep® 4 is also equipped with a replaceable electrode with a round stainless steel connector. This electrode has no pins to align, which could break or bend. The replaceable HI73127 pH electrode features a removable fiber junction. This type of junction can be renewed by pulling it out approximately 3 mm (1/8 ") and allows for the removal of any potential clogs, improving response time and measurement stability.
