product overview

HOBO U24-002-C is a new conductivity recorder developed by ONSET, which is used to measure relatively small changes (± 5000 μ S/cm) in salinity, conductivity and temperature in the seawater environment, such as the bay of seawater, or detect salinity events such as surge, rainstorm and discharge events. It can also be used to collect salinity content data during the salinity compensation of dissolved oxygen recording data in HOBO U26.
Attention: Beyond the water area+Monitoring salinity changes at a rate of -5000 us/cm, please refer to the accuracy shown in product specification scenario C to determine if the accuracy is acceptable for your needs. Monthly on-site calibration readings typically require optimal accuracy.
