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. We have always valued
your comments and suggestions and in this new series, we have included all
the features you have asked for and more!
The waterproof pHep® 4 and pHep® 5
pH testers have a dual-level LCD that displays pH and °C or °F. At
startup, pHep® performs a self check then displays the
remaining battery level to assure proper working condition. These testers
also feature 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 pH/Temperature meters have a stainless steel
temperature probe for faster and more precise temperature measurement and
auto-compensation. 1 or 2 point calibration is made simple with automatic
recognition of both standard and NIST buffer sets. We have designed the new pHep®
pH electrodes with an extendable reference junction and when the
electrode finally is exhausted simply insert a new electrode cartridge!
