Solinst Levelogger 5 LTC

  • Increased memory 100,000 sets of data
  • More stable communication Single-eye optical, easy to clean, more scratch resistant
  • Better thermistor and conductivity sensitivity Upgraded platinum RTD and conductivity sensor
Product Options


The Levelogger 5 LTC logs level, temperature and conductivity by combining a datalogger, an 8 year battery, Hastelloy® pressure sensor, temperature detector and conductivity sensor all in a small waterproof housing with a size of 22mm x 208mm. The body of the Levelogger is protected against corrosion, abrasion and high temperatures by the baked-on coating that uses polymerisation technology. The conductivity sensor is a 4-electrode platinum sensor, with autoranging capabilities. The minimal-maintenance, sealed Levelogger 5 LTC is simple to clean and calibrate, even in the field. The levelogger 5 LTC also has increased memory compared to it's predecessor, this memory can now hold up to 100,000 sets of data.

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.
  • Program and start dataloggers in the field.
  • Simplify data management in the field by transporting and using less equipment.
  • View real-time readings.
  • Download and e-mail logged data files.
  • Calibrate LTC Leveloggers (NEW).
  • Run the diagnostic utility (NEW) – used for troubleshooting

Leveloggers. Provides detailed information on the datalogger,
and includes options for running a self-test, doing a memory
dump and creating/emailing reports.
