Product Options


The LTC Levelogger Edge measures conductivity, water level and temperature. It combines a datalogger, pressure sensor, temperature detector and conductivity sensor within a compact Hastelloy, waterproof housing. Measuring 7/8" x 7.5" (22 mm x 190 mm), the LTC Levelogger Edge includes a titanium ceramic PVD coating to protect the sensor from corrosion.

The conductivity sensor is a 4-electrode platinum sensor that is capable of auto-ranging. The LTC Levelogger Edge is practical for field use as the datalogger requires minimal maintenance, is simple to clean and calibrate and has an 8 year battery life. It's memory is non-volatile and can store up to 27,000 readings.

The LTC Levelogger Edge can be installed with direct read cables or cord suspension for easy deployment. It is compatible with the 3001 Levelogger Series including Solinst Telemetry, Bluetooth App Devices and Data Grabber so data can be downloaded in the field.
