  • Dual Level Display Showing pH & Temp.
  • Rugged, Floating Waterproof Casing
  • Replaceable pH Electrode Featuring an Extendable Junction

    The waterproof  pHep 5 pH tester has 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 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!

     HI 98128 (pHep5) is supplied complete with protective cap, electrode removal tool, batteries and instructions.
