Hanna Instruments HI98128 (pHep-5) Waterproof Combo High Precision pH Meter & Thermometer

The HI98128 (pHep-5) is a waterproof combination pH tester and thermometer by Hanna Instruments. The dual-level LCD displays both pH and temperature in °C or °F.  At startup, it performs a self-check then displays the remaining battery level. This tester also features a hold feature to prompt the user when to take the reading & freezes the display for easy and accurate recording. The temperature probe is stainless steel, for faster and more precise temperature measurement.

The HI98128 is supplied complete with 4 x 1.5V batteries, pH electrode and electrode replacement tool.

Do you also need to measure conductivity?  Consider our two models of 4-in-1 combo meters for pH/EC/TDS and temperature:  the HI98129 (for lower range EC/TDS) or the HI98130 (for higher range EC/TDS).
