  ENV4.10  and  ENV4.11

pHep4 and pHep5 pH Temperature Testers

These waterproof testers have a dual-level LCD screen that displays pH and temperature (oC or oF).  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 and freeze the display for easy and accurate recording. 

Other features:

  • Rugged buoyant waterproof casing

  • Stainless steel temperature probe for precise measurement and auto-compensation

  • One or two point calibration with automatic recognition of both standard and NIST buffer sets

  • Replaceable pH electrode with an extendable junction

Each unit is supplied with batteries, instructions, a protective cap for the electrode, and a special removal tool for electrode replacement.
