Description

Description

The HHWT-SD1 is a general purpose handheld instrument capableof measuring the pH, Oxidation-Reduction Potential (ORP) orconductivity of a solution, as well as its TDS (Total DissolvedSolids), DO (Dissolved Oxygen) or salt content. Using the includedconductivity/TDS/salt probe, an optional DO probe, and optionalORP or pH electrodes the meter can measure pH from 0 to 14,ORP from -1999 mV to 1999 mV, conductivity up to 200 mS(milliSiemens), TDS up to 132,000 ppm, DO up to 20 mg/L, andsalt content up to 12% by weight.The HHWT-SD1 is designed for water conditioning, wastewatermonitoring, beverage production, aquaculture (fish farming),aquariums, pulp and paper processing, electroplating, andphotography applications. A front-panel pushbutton enables rapidswitching among the meter’s four measurement modes.Because it is microprocessor-based, the HHWT-SD1 is portable,reliable and has the large storage capacities that SD memorycards offer. Measurements can be made automatically at anysampling rate between one second and nine hours. After timestampingand storing the measurements on an SD card pluggedinto the meter, the user can remove the card and plug it into to acomputer either directly or via a USB card reader. The values arestored on the card as files with the .xls extension, which can beopened by Microsoft’s Excel® application.
