Level Datalogger

Data logging water level sensors or levellogger is a submersible level sensor with data logger are ideal for observing flow patterns, testing pumps, and monitoring groundwater, well, streams, lakes, wetlands, tanks and tidal levels long-term or short-term. It is a research-grade data logger for continuous monitoring of water level, temperature and conductivity a depths of up to 300mH2O. The data that they collect and store can be downloaded to a portable computer in the field. Features 0.05% measurement accuracy, a SS316L or Titanium housing for use in both freshwater and saltwater. Pokcenser provides vented design and non-vented design for the convenience deployment of different applications.
