| Hanna Instruments HI 98128 (pHep-5) Waterproof Combo pH Meter & Thermometer |
|
TheHI 98128(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 HI 98128 is supplied complete with 4 x 1.5V batteries,
pH electrode and electrode replacement tool. For calibration use the appropriate pH buffers.
The replacement probe is HI 73127.
Do you also need to measure conductivity? Consider our two models of 4-in-1 combo meters for pH/EC/TDS and temperature: the HI 98129 (for lower range EC/TDS) or the HI 98130 (for higher range EC/TDS).
