This meter, which is the result of over two decades of research and manufacturing experience, is the updated version of Hanna's widely popular 96107. Today the redesigned pHep series feature a rugged and ergonomically enhanced casing that fits comfortably in your hand and a larger LCD which makes it easier to read at any angle. With the latest innovation of a non-clogging fiber junction the new pHep meters last much longer. Simply pull out 1-2mm of the junction fiber to completely renew the junction. 

The pHep offers a Range of 0.0 ti 14.0pH and an accuracy of plus or minus 0.1pH. This testeer is calibrated manually to 2 points. 

Comes with a protective cap, calibration screwdriver, batteries and instructions.
