pHep 4 & pHep 5, Waterproof pH Testers

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!

  • pHep® 4 (50-HI98127) has the most common pH range of 0.0 - 14.0 pH
  • pHep® 5 (50-HI98128) has a more precise pH range of 0.00 - 14.00 pH
