For those who work with water most of the time, an efficient pH and conductivity meter is very important. Extech EC500 Waterproof ExStik II pH/Conductivity Meter is helpful equipment with regards to water testing. The device is capable of reading 5 different parameters which include pH, Conductivity, TDS, Salinity and Temperature. It has the ability to measure these parameters in 9 different units of measurements namely, pH, μS/cm, mS/cm,ppm, ppt, mg/L, g/L, °C, °F. On the display with which the meter comes, an analogue bar graph is provided to help you see the long term consistencies that will possibly point out the reasons for poor water quality. This conductivity meter is capable of storing up to 25 readings with its internal memory.
