The Hydrolab HL4 is the next generation multiparameter water quality sonde from OTT Hydromet. Its reliability, ease-of-use, and metadata produce water quality data you can trust.
Know the sonde is working correctly and troubleshoot quickly with the self-monitoring system that reports the status of the sonde, shows the user where potential problems are, and gives assistance on how to solve issues. Calibration is made easier with streamlined calibration tasks with user-scheduled calibration intervals and a check calibration procedure that can be used to avoid a complete calibration. Produce valid, scientifically defensible conclusions with sensor status that is saved with every line of data and calibration reports that store information about previous calibrations.
