Conductivity & Salinity Data Loggers and Recorders

Conductivity & Salinity data loggers measure and record conductivity and salinity levels in water or other liquid solutions. These devices come in a wide variety of types to suit different applications. Handheld devices are perfect for lab testing, spot checking, or any other application where results need to be checked quickly. Sealed units are built with rugged waterproof housings and designed for long term deployments for fresh or saltwater applications.


MicroDAQ.com offers a large selection of loggers ensuring that we probably have multiple options for almost any application. Our Technical Sales Representatives are available by chat, email, or phone and they are always happy to help you find the best solution for your particular application.
