Hanna Instruments HI 9811-5N pH Waterproof Meter with a Water-Resistant, 6000 microSiemens/cm Conductivity and Temperature

The Hanna Instruments HI 9811-5N is a waterproof multi-parameter meter for measuring electro-conductivity (EC), Total Dissolved Solids (TDS), pH, and temperature all in one device.

The meter features a large LCD screen for readability, and automatic temperature compensation to eliminate the need for additional calculations. The meter can be calibrated at one point for pH, EC or TDS.

pH range is 0.0 to 14.0 pH, + or - 0.1 pH, with resolution 0.1 pH. EC range is 0 to 6000 uS/cm + or - 2% F.S. with resolution 10 uS/cm. TDS range is 0 to 3000 ppm (mg/L) + or - 2% F.S. with resolution 10 ppm (mg/L).Temperature range is 0.0 to 70.0°C, + or - 1 degree C, with resolution 0 degree C. Dimensions are 144.6 x 79.5 x 37 mm (5.7 x 3.1 x 1.5”) and weighs 230 g (8.1 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 its products, Hanna is a vertically integrated manufacturer and does not subcontract any part of its manufacturing.
