The Hanna Instruments HI 98130 waterproof floating tester displays pH, high-range conductivity (EC) and total dissolved solids (TDS) with Automatic Temperature Compensation (ATC) on a dual-level LCD display for hydroponics, agricultural, and water quality testing applications. The meter provides automatic 2-point pH calibration and automatic 1-point calibration for EC and TDS. The HI 73127 pH electrode is replaceable, and has a stainless steel snap-in connector that prevents bent or broken pins. The pH electrode cloth junction is renewable and can be pulled out further when the electrode is soiled to extend the life of the electrode. The conductivity electrode is made from graphite, which eliminates contamination from salt deposits in the solution being tested. The exposed temperature sensor provides quick response and accurate, ATC readings.
The tester has a number of power management features, including the percentage of remaining battery power displayed at startup, automatic shut-off after eight minutes of inactivity, and a battery error prevention system that alerts the user when battery is low to avoid issues with parameter readings. The tester comes with a pH electrode, electrode removal tool, and four 1.5V batteries.

A multiparameter meter is a benchtop or handheld device that can take multiple readings on a single sample. It measures parameters such as the pH level (acidity or alkalinity of a substance), conductivity (the amount of salts or other compounds present in water), dissolved oxygen (DO, the amount of oxygen in a liquid), temperature, total dissolved solids (TDS, anything present in water other than the pure water molecule and suspended solids), salinity, resistivity, and oxidation reduction potential (ORP). Applications for multiparameter meters include water testing, pharmaceuticals, agriculture, winemaking, water-treatment plants, and acquaculture. Devices with a benchtop body are often used for indoor laboratory use or in a manufacturing setting; handheld, portable devices are typically used for fieldwork. Sensors are used with a meter to measure the parameters of a substance.
