GrowProbe is a low-cost, multi-parameter water-quality logger for marine and freshwater monitoring. Deploy it for up to several months to log light, temperature, current speed and direction, and turbidity, then download a clean CSV and see what your water has been doing. Built for aquaculture and seaweed farms, restoration projects, researchers and environmental teams, GrowProbe puts continuous water-quality data within reach of budgets that incumbent sondes price out. Deploy it on the seabed, floating, or inverted, with programmable sampling (set the wake interval and the samples per burst). Turbidity readings are calibrated with included calibration fluids optimised for 0 - 40NTU range.. Current speed and direction readings are not calibrated (raw tilt angle output, optimised for range 0 to 2.5 knots). Check our downloadable sample data file to see typical output before you buy.
