Hanna Instruments pH/Conductivity/TDS High-Range Tester

This rugged, high-range tester provides accurate pH, conductivity, TDS, and temperature measurements. Results are shown on an easy-to-read LCD display, and the tester features a pH electrode cartridge with an extendable cloth junction that ensures long life. The EC/TDS conversion factor and temperature compensation coefficient (ß) are user-selectable. This waterproof meter is designed to float and features an EC/TDS graphite electrode, automatic temperature compensation, automatic one-point or two-point pH calibration, HOLD function, automatic shut-off, simple two-button operation, and switchable °F/°C readout. Battery percentage is displayed during startup, and the Battery Error Prevention System guards against inaccurate measurements. Includes tester, replaceable pH electrode, electrode removal tool, batteries, and instructions.

This is the first ph meter I have ever used. Instructions were complete and detailed. Field results were not as stable as I had hoped, but the error was likely user based, or some other variable that I have not accounted for.


We have purchased several of these meters for use in-house and by our clients. They offer a simple interface and reliable functionality. The labeling on the buttons is a bit counter-intuitive to the novice user. Calibration is simple. For the money; this is a must-have.
