The SensoRex Toroidal Conductivity Kit is a portable conductivity meter kit designed for water quality testing. It includes a toroidal conductivity sensor, calibration solutions, carrying case, and 9V battery. The meter has a measurement range of 0 to 1999 μS/cm, resolution of 1 μS/cm, and accuracy of ±2% full scale. The toroidal sensor provides flow-through measurement and resists polarization and fouling. This kit is ideal for testing drinking water, wastewater, process water, and more. The rugged carrying case allows for convenient field use.
