Required Accessories
Power supply
HyQual probes require a source of power.
Choices of power supply out of the water:
⁻
For spot measurements, the optional external rechargeable Bluetooth® wireless technology bat-
tery enclosed in a waterproof (IP67) case connects to the probe via the
HyQual probe‘s standard
underwater cable running RS-232 or SDI-12. This battery operates only at the surface and its job
is to power the multiprobe while you’re pairing the instrument with a data display via
Bluetooth
® wireless technology.
⁻
A USB port on a PC is another way of suppling power to the multi-probes. For this case you
would need to add the optional USB adapter.
⁻
HyQual also connects to third-party devices (data loggers, samplers, telemetry, etc.) that supply
power.
Choices of power supply that operate underwater:
⁻
Instead of using power from the underwater cable you could use the optional EBP external re-
chargeable battery pack. This battery is ideal for HyQual 300 and 300 T due to its 75 mm (3 “)
diameter. It also works fine with the 200 version, only it makes it look top heavy. Use the EBP
external battery pack when you do not wish to have downtimes of charging the battery. The EPB
is removable so you can replace it with a freshly charged battery right in the field. Please note
that the use of EBP adds several millimeters to the length of the multiprobe.
Communication and connection
Available for the HyQual probes is an optional SDI-12 and ModBus interface, with either an SDI-12 or
MODBUS adapter cable.
