The TechPro II series of meters provide conductivity/TDS measurements for applications such as boilers and cooling towers, reverse osmosis, pools and spas, pulp and paper, and many other industries. The meters require only a 5-mL sample for conductivity measurements. Both the temperature-compensated measurement of interest and the sample temperature is displayed on the four-digit LCD. The meters have autoranging function for greater resolution of your conductivity measurements between 0 and 9999 µS or 10 to 20.00 mS.
