solinst levelogger app interface bluetooth wireless device


The Levelogger® App Interface uses Bluetooth® wireless technology to connect a Solinst datalogger to Apple® devices running iOS 11, or later. Please see list of supported devices on the last page of this quick start guide.

Once connected, you can use the Solinst Levelogger App to communicate with the datalogger. The Solinst Levelogger App allows you to view real time data from the connected datalogger, as well as view and download logged readings. You can also program the dataloggers or apply a saved settings file.

The Levelogger App Interface is compatible with the Levelogger Edge, Barologger Edge, Levelogger Junior Edge, LTC Levelogger Edge, Rainlogger Edge, LevelVent, and AquaVent, as well as Levelogger Gold, Barologger Gold, Levelogger Junior, LTC Levelogger Junior, and Rainlogger dataloggers.


Levelogger App Interface


The Levelogger App Interface connects to the top end of a Levelogger's Direct Read Cable or Adaptor, a LevelVent Wellhead or an AquaVent Wellhead Connector Cable.

To connect the Levelogger App Interface, simply hold onto the top end of the Direct Read/Connector Cable/Wellhead, and thread the coupling of the Levelogger App Interface onto the connection. The threaded connection is designed to be stable when installed on a Direct Read Cable or LevelVent Wellhead in a Solinst 2" Well Cap Assembly.

Alternatively, you can use a Direct Read to Optical Adaptor, when a Direct Read Cable is not being used. Simply thread the Levelogger to the optical end, and the Levelogger App Interface to the other connection. A slip fit version is also available
