The LHM/LHC range of probe-loggers offers an integrated, easy to implement solution for continuous or temporary hydrometric monitoring of boreholes, as well as streams and rivers.

The unique characteristics of this range of probes with integrated data loggers is that it offers the following 5 useful measurements, in a unique and compact product: water pressure, air pressure, water level, water temperature, air temperature.

The LHC model integrates a cellular modem for the transmission of measurements by telemetry.
For manual readings, without telemetry, see the LHM model

Applications

  • Level and temperature monitoring in boreholes, piezometers, watercourses...
  • Isolated sites with no power supply

Main benefits

  • Compact and easy to implement
  • Direct integration in piezometers and wellheads (discrete and fast installation)
  • Integrated air pressure compensation and direct water level calculation
  • High accuracy of digital pressure sensors
  • Ease of data reading since the immersed sensors can remain in place while the data logger is on the outside and directly accessible to the operators.
  • Ease of battery change for the same reason as the batteries are in the data logger
  • Battery life (up to 10 years)
  • Automatic transmission of measurements by telemetry, with various data reception and processing options
