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.
