2.7 The USB converter
Eijkelkamp’s USB converter converts your Scuba’s data stream to a USB port. Newer models have a power port on the
side that you can use to provide power to the Scuba if USB power is insufficient, or to protect your laptop’s battery. The
connector is fairly standard for power supplies, so you can plug in many third-party power supplies – but do not use a
power supply providing over 14 VDC.
If you are using a power supply that plugs into the wall, please use a GFI-equipped circuit.
2.8 Accessories
Eijkelkamp provides a number of accessories for the Scuba, including carrying cases, anti-fouling kits, SDI-12 converters,
data displays, telemetry systems, cable reels, etc.
2.9 Flow cell
If it is more convenient to bring the water to the Scuba than the Scuba to the water,
for instance when monitoring a ground-water well, you can simply screw a flow cell
onto the Scuba as you would normally screw on a sensor guard.
The flow cell cannot be used in combination with low flow pumping.
2.10 Routine maintenance
Clean your instrument periodically with warm soapy water. Liquid dishwashing soap
is fine. Do not use abrasives. Do not use acetone. Do not clean with gasoline,
kerosene, or industrial cleaners. Mild household cleaners work well. Clean sensor
stems with a soft brush.
Rinse well with tap water, and store sensors with tap water in the storage cup.
Replace any o-rings with visible cracks. Keep o-rings greased with silicon grease
(found in your maintenance kit). Always remove batteries and clean your Scuba
prior to storing it for prolonged periods.
