Getting Started
App Description
This application enables wireless Bluetooth communication with the designated
device. The Model 3000-Series of Ludlum’s digital survey meters, already known
for their versatility and user-friendly operation are ideal for this
application, Ludlum Measurements has expanded the features and options for the
Model 3000-Series instruments. These instruments may be upgraded with
Bluetooth 4.0 LE® (Bluetooth Low Energy, sometimes referred to as Bluetooth
Smart) for wireless connectivity. This feature permits wireless transmission
of readings from a connected instrument, allowing operators to remotely
monitor the live data on the screen of their mobile device. Additionally, this
combination enables the discrete operation of the radiation detection
instrument. When paired with Linker App the operator can seamlessly send data
to the *Rad Responder Network, which provides a central location for up-to-
date information from operators in the field. Reported data includes user,
radiometric survey, survey notes, and GPS location, as well as details about
the instrument and detector being used. This information can be shared with
remote personnel instantly, greatly improving the speed and accuracy of
acquiring and reviewing survey data.
