Water resistant pocket pH, conductivity (EC) up to 3999 µS/c

The ultimate combination tester from Hanna! HI 98129 is a waterproof tester that guarantees very accurate results for pH, EC / TDS and temperature measurements and this with a single tester! You no longer need to change meters for your routine measurements. These floating water resistant testers feature a large easy-to-read two-part LCD display and auto shut-off. pH and EC / TDS measurements are automatically temperature compensated (ATC). You no longer have to throw away your tester when the pH electrode is used up. These technologically advanced testers have a replaceable electrode with both a cloth junction and a graphite EC / TDS electrode that resists contamination from salts and other substances. This makes these testers last longer. The user can choose the EC / TDS conversion factor and the temperature compensation coefficient (ß). Fast, efficient, accurate and portable, the combo tester for pH, EC / TDS and temperature gives you the functions you need and more!

Replaceable pH electrode

The combo has an easily replaceable pH electrode and a pull-out cloth junction. A sturdy 'snap-in' connector means there are no pins to bend or break.

High accuracy

The graphite conductivity electrode provides greater accuracy because it cannot be contaminated by salts in the solution. The temperature sensor has a fast response time and guarantees accurate temperature-compensated measurements.

Battery status on the screen

The LCD screen shows the battery percentage at start-up

Standard or NIST buffer calibration

Automatic calibration is performed with two sets of memorized buffers for greater accuracy.

Adjustable TDS ratio

For accurate measurements, users can choose between different conversion factors from conductivity (EC) to TDS.
