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 the included
conductivity/TDS/salt probe, an optional DO probe, and optional
ORP 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, and
salt content up to 12% by weight.
The HHWT-SD1 is designed for water conditioning, wastewater
monitoring, beverage production, aquaculture (fish farming),
aquariums, pulp and paper processing, electroplating, and
photography applications. A front-panel pushbutton enables rapid
switching 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 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, the user can remove the card and plug it into to a
computer either directly or via a USB card reader. The values are
stored on the card as files with the .xls extension, which can be
opened by Microsoft’s Excel
®
application.
