Hanna pH Tester

The Hanna Instruments Waterproof pHep4 pH/Temperature Tester has a dual-level LCD that displays pH and °C or °F. At startup, the tester performs a self check then displays the remaining battery level to assure proper working condition. This pH/Temperature Tester also features a stability indicator and hold feature to prompt the user when to take the reading & freeze the display for easy and accurate recording. These new meters have a stainless steel temperature probe for faster and more precise measurement and auto-compensation. 1 or 2 point calibration is made simple with automatic recognition of both standard and NIST buffer sets. Hanna Instruments has designed the new pH electrodes with an extendable reference junction and when the electrode finally is exhausted simply insert a new electrode cartridge!

When Hanna Instruments introduced it's first version of the pHep (pH electronic paper) in 1986, it immediately revolutionized the standards in pH measurement. The pHep's ease-of-use in combination with its affordability made it possible for non-technical and technical personnel alike to accurately measure pH on the spot. Since then, over 1 million pHeps have gone to satisfied customers around the world.
