This rugged, handheld digital conductivity meter is built for field use with a waterproof case that will float if accidentally dropped and a built-in storage chamber for protecting the probe when not in use. The meter comes complete with a 4 electrode conductivity cell in your choice of cable lengths. The LCD read-out simultaneously displays temperature (°C) along with the conductivity (uS/cm or mS/cm) or salinity (ppt).
