The D505 data logger from Beaded Stream has several configurable options at order. Learn about each configuration option below.

# of XLR Cable Ports

The D505 logger can have between two and four XLR ports. Two is the default number, each additional port costs $125. Each port supports one Beaded Stream digital temperature cable.

Sonice Range Finder

Sonice Range Finder
Measures water or snow depth. You may still have 4 XLR connections along with the sonic range finder. Only one range finder per logger. Adds $550 to logger price.

Power Source

Lead Acid Battery
Lead Acid Battery
This is the default power option for the D505. The lead acid battery provides three months of continuous power without recharge and virtually unlimited power life when paired with the solar panel recharge option at no additional cost.

Recharge Option

Solar Panel
Solar Panel
The solar panel recharge option is only available in tandem with the lead acid battery. Thanks to Beaded Stream’s ultra low-power digital temperature cables the solar panel can provide the D505 logger with virtually limitless battery life.

Data Plan

Data Plans
All D505 loggers come with an Iridium embedded two-way satellite data transceiver and integrated Iridium antenna allowing wireless transmission of your data from any location on the planet. Data plans are $800 annually and include transmission, storage and a Beaded Stream data analytics dashboard.

Box Color

The default color for all D505 housings, the high-visibility yellow makes it easy to spot your equipment in limited visibility weather and in low light environments.
