The TDSH-1 and TDSH-2 Total Dissolved Solids (TDS) Testers
are housed in water-resistant ABS cases for use in a variety of environments such as water treatment plants, fish farms, aquariums, and industrial pollution control. There are two different models to choose from, depending upon the range to be measured. The TDSH-1 with a range of
1,990 ppm is recommended for low TDS measurements such as in cooling waters. The TDSH-2 has a range of 10,000 ppm for use in HVAC and other high TDS applications.
Two conductivity models are available. The CDH-2 has a range of 1,990 ╡S/cm for drinking water, swimming pools and other low conductivity samples. For agriculture and wastewater, the CDH-3 with a range of 19,900 ╡S/cm is recommended.
The CDH-2 and CDH-3 Conductivity Testers are also water-resistant, and are recommended for agriculture, cooling towers, boilers, and water purification plants.
