The HI 98204 is a portable waterproof meter that measures pH, oxidation reduction potential (ORP), and electroconductivity (EC) all in one device.
The meter features a large LCD screen and a VALOX body for use both outside and in the lab. pH calibration is manual at two points, conductivity calibration is manual at one point, and ORP and temperature are factory calibrated. After calibration, fill the device with the sample liquid and press “range” to take a reading.
pH range is 0.0 to 14.00 (+ or - 0.2 pH) with a resolution of 0.1 pH. Temperature range is 0.0 to 60.0 degrees C + or – 1 degree C with a resolution of 0.1 degree C. ORP range is + or – 1000 mV + or – 5 mV, with a resolution of 1 mV. Conductivity range is 0 to 1999 uS/cm, + or – 2% F.S. with a resolution of 1 uS/cm. The device operates on three 1.5 V batteries, which provides approximately 200 hours of use. Dimensions are 190 x 85 x 85 mm (7.5 x 3.3 x 3.3 ") with weight 260 g (9.2 oz.).
pH testers measure the acidity or alkalinity of a substance and are commonly used by researchers, manufacturers, and hobbyists.
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 the world’s first pH electrode with a built-in temperature sensor, electronic pocket-sized pH tester, and replaceable electrode pH pocket tester. To ensure the quality of its products, Hanna is a vertically integrated manufacturer and does not subcontract any part of its manufacturing.
