HI-98127/HI-98129 pHep4/pHep5 pH/Conductivity waterproof Tester

This lightweight, waterproof tester offers high accuracy pH and temperature measurements in a single handheld unit! The large LCD display shows both pH and temperature readings simultaneously, while a stability indicator is displayed to alert you when a stable reading has been obtained.

  • The pHep®4 HI98127 pH Tester has a replaceable elctrode for longer tester life.. The pHep®4 is a waterproof ph tester for water with a 0.1 pH resolution and an accuracy of ±0.1 pH. It has many advanced features that are found in more expensive portable instrumentation. One or two-point calibration is automatic to two selectable buffer sets (4.01, 7.01 and 10.01 or 4.01, 6.86, and 9.18). The pHep®4 also features a replaceable electrode with a stainless steel round connector. This cartridge design has no pins to line up or that can break. The HI73127 replacement pH electrode also features an extractable cloth junction. The extractable cloth junction of the HI73127 allows for the renewing of the junction. Simply extract ⅛” of the junction by pulling on the junction will expose a new portion. Any clogging that was present will be cleared and the response time will be back to normal extending the life of the pH electrode.
  •  The HI98129 is an easy-to-use and accurate waterproof pH, conductivity, TDS (ppm) tester. It measures pH, EC in the low range (0 to 3999 µS/cm), TDS (0 to 2000 ppm), and temperature. This floating, waterproof combination pocket tester has an easy to read, LCD and an automatic shut-off. All pH, EC, and TDS (ppm) readings are automatically temperature compensated (ATC) to prevent temperature-related variations in your measurements. For EC and TDS (ppm) readings, the EC/TDS conversion factor (CONV) is selectable by the user. The HI98129 tester features an easy to replace pH electrode cartridge with an extendable cloth junction.
