Take precise measurements of total dissolved solids with Series TDS. Lightweight and compact, these testers are ideal for field testing of TDS concentrations. Large easy-to-read LCD displays the full scale readout in ppm (parts per million), no additional calculations are required to obtain actual test values. Durable 316 stainless steel electrodes provide excellent chemical compatibility. Automatic temperature compensation from 32 to 122°F (0 to 50°C), ensures reliable, repeatable results. Additional features include flip-up battery compartment, sturdy pocket clip, and a splash-resistant membrane keypad.
