The Hanna Instruments HI 98303 is a handheld pH and Total Dissolved Solids (TDS) meter with a graphite sensor and an ergonomically designed, reinforced plastic casing.
The meter features a large LCD screen, and Automatic Temperature Compensation (ATC) from 0 to 50 degrees C. The device operates on four 1.5V batteries, and has a battery error protection system that turns the meter off if the battery is low enough to produce erroneous readings.
To calibrate, submerge the electrode tip into the calibration solution and adjust the tester. Calibration is manual at one point. Conductivity range is 1999 us/cm, + or - 2% F.S with resolution 1 us/cm. Its dimensions are 175 x 41 x 23 mm (6.9 x 1.6 x 0.9"), and weighs 95 g (3.4 oz.).
Conductivity meters are used for measuring the electro-conductivity of a solution. They are commonly used in hydroponics, aquaculture, and research to measure the amount of salts or other compounds present in water.
Hanna Instruments manufactures a wide variety of analytical instrumentation, including pH meters, multi-parameter meters, electrodes, chemical reagents and buffer solutions. Founded in 1978, Hanna is headquartered in Woonsocket, RI, with subsidiaries in 32 countries. Hanna Instruments holds many firsts in the field of analytical instrumentation, including a pH electrode with a built-in temperature sensor, an electronic pocket-sized pH tester, and a replaceable electrode pH pocket tester. To ensure the quality of their products, Hanna is a vertically integrated manufacturer and does not subcontract any part of its manufacturing.
