The Hanna Instruments HI 99301 portable meter is a waterproof, multi-parameter electro-conductivity, TDS, and temperature meter designed for agricultural applications.
The meter features a large LCD screen for readability, and automatic temperature compensation to eliminate the need for additional calculations. The temperature range is factory calibrated, while electro-conductivity (EC) and total dissolved solids (TDS) calibration is automatic at one point (1413 uS/cm).
The HI 99301 can measure EC in the range of 0 to 3999 uS/cm (+ or - 2% F.S.) with resolution 1 uS/cm. TDS range is 0 to 2000 ppm (+ or - 2% F.S.) with resolution 1 ppm. Temperature range is 0.0 to 60.0 degrees C (32 to 140 degrees F) (+ or - 0.5 degrees C [+ or – 1 degrees F]) with resolution 0.1 degrees C (0.1 degrees F). Dimensions are 160 by 105 by 31 mm (6.3 by 4.1 by 1.2") with weight 190 g (6.7 oz.).
Conductivity meters measure 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 its products, Hanna is a vertically integrated manufacturer and does not subcontract any part of its manufacturing.
