Never again out of battery power!

At least not in the field during an ADCP discharge measurement. There is certainly no point in time less opportune for a battery failure than at the measurement site, often coinciding with bad weather, at a poorly-accessible river bank.

The TrueVoltage Option for our DataLog Wireless Hydro and Datalog Wireless Hydro XR monitors the voltage of your battery. You will be notified well in advance of capacity running out, giving you the chance to replace the battery and to avoid the risk of unavailability of your ADCP sensor.
