Extech EC405 ExStik Replacement pH Electrode/Conductivity Cell Module is a replacement 4-in-1 conductivity cell for ExStik Conductivity meters. It's flat surface design provides a rigid structure that is difficult to damage, but easy to clean. The Extech EC405 is ideal for direct contact applications such as food, paper, cement and wet surface.
Extech EC510 Waterproof pH/Conductivity Meter Kit measures 5 parameters including Conductivity, TDS,Salinity, pH, and Temperature using one electrode. Extech EC510 has an innovative design with flat surface technology for quick on-the-spot pH measurements combined with autoranging high accuracy Conductivity cell.
With the Extech EC500’s rugged flat surface design and dynamic cell-constant technology it is possible to measure a wide range of Conductivity, TDS, and Salinity with the same electrode. This Extech EC500 uses 9 units of measuresurements which are pH, μS/cm, mS/cm,ppm, ppt, mg/L, g/L, °C, °F. Careful use and maintenance of Extech EC500 will provide years of reliable service.
