Product Options



The LTC Levelogger Junior conductivity datalogger (CTD) measures conductivity, temperature and depth all in one CTD device. It combines all three parameters within one conductivity data logger and has a 5 year battery life, memory capacity for 16,000 sets of readings in a small waterproof housing. Like the Levelogger Junior water level datalogger, it is very easy to program as well as being very small and easy to deploy in a range of environments and applications.

The LTC conductivity datalogger is totally compatible with Levelogger Software and all accessories as well is being able to be integrated into telemetry systems.

The 4-poll electrode platinum conductivity sensor has auto-ranging capabilities. The sealed conductivity data logger requires minimal maintenance and is simple to clean and calibrate, even in the field. Copper wire surrounds are also available to prevent algal/molusc growth around the sensor.

The Solinst CTD displays conductivity, temperature and temperature-compensated water level when using the standard Levelogger Software. The data logger can also record up to 16,000 sets of data readings. Measurements are linear and are taken at user defined intervals between 5 seconds and 99 hours.

As the Levelogger App Interface will not connect directly to the top of a Solinst datalogger, it is necessary to have connection accessories. With the Levelogger or Rainlogger, one of the following accessories is required:

  • Direct Read Cable, clients use this option to suspend dataloggers in the field when they wish to communicate downhole.
  • When working with Leveloggers that are suspended from wireline, or cord, the units must be removed from the well and connected to either a Direct Read Cable (as above) or an Optical Adaptor.
  • For the LevelVent, just connect to the unit via the Vented Cable and LevelVent Wellhead that all units are suspended from in the field – no other connection accessories are required.
  • The AquaVent communication connection is made from the App Interface to the AquaVent Wellhead using an App Connector Cable that is ordered separately.
The Levelogger App Interface is portable hardware that connects to the top of your Levelogger via a Direct Read Cable/Adaptor, to a LevelVent Wellhead, or to an AquaVent Wellhead cable. Bluetooth wireless technology allows communication between the Levelogger App Interface and the smart device with the app installed. It allows viewing/downloading of data, and programming of Solinst dataloggers, as well as many other features.
Solinst offers a wide range of dataloggers that can be used with the Leveloggger App Interface. They include the complete, current Levelogger Edge range of units (Edge, Junior Edge, LTC Edge, Rainlogger Edge), previous Gold Leveloggers/Barologgers, and the latest vented datalogger editions, the AquaVent and LevelVent.
