HHWT-SD1 pH, ORP, Conductivity, TDS, Salt and DO Meter with Data Logging SD Card
■Thank you for purchasing Omega's HHWT-SD1 pH, ORP, Conductivity, TDS, Salt and DO Meter with Datalogging SD Card. Please read this user's manual carefully and thoroughly before using the instrument.
■The HHWT-SD1 is a general purpose handheld instrument capable of measuring the pH, oxidation reduction potential (ORP) or conductivity of a solution, as well as its TDS (total dissolved solids), DO (dissolved oxygen) or salt content. Using an included conductivity/TDS/salt probe, an optional DO probe, and optional ORP and 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, and salt content up to 12% by weight.
■The meter also accepts an optional automatic temperature compensation (ATC) probe that configures a pH electrode to measure solutions at temperatures between 32º and 150ºF (0º and 65ºC). For measuring the pH of solutions at temperatures between 32º and 212ºF (0º and 100ºC), the temperature compensation can be set manually. pH electrodes must be calibrated for pH 4, pH 7 and pH 10 using buffer solutions, as do conductivity/TDS/salt probes and oxygen probes using their own standard solutions.
■Among the applications and environments suitable for the HHWT-SD1 are water conditioning, wastewater monitoring, beverage production, aquaculture (fish farming), aquariums, pulp and paper processing, electroplating, and photography.
■The HHWT-SD1 has the performance and features needed to satisfy the most demanding aspects of the above applications. A front-panel pushbutton enables rapid switching among the meter's four measurement modes.
■Because it is microprocessor-based, the HHWT-SD1 can make full use of the portability, reliability and large storage capacities that SD memory cards offer. Measurements can be made automatically at any sampling rate between one second and nine hours. After timestamping and storing the measurements on an SD card plugged into the meter (a process called datalogging), the user can remove the card and plug it into to a laptop or desktop computer either directly or via a USB card reader. The data logs are stored on the card as files with the .xls extension, which can be opened by Microsoft's Excel application
■The HHWT-SD1 has a backlit 2-1/2 in. diagonal display and is powered by six ''AA'' Alkaline batteries or an optional 9-VDC AC adapter.
