SMM - Soil Moisture Meter

Overview

The Soil Moisture Meter (SMM) is a stand-alone logging instrument for the measurement of  soil volumetric moisture content of soils and other materials.
The SMM can support up to 10 x standing wave sensors (MP406 or MP306) or up to 10 x capacitance sensors.
The SMM is a fully self-contained unit requiring power input form a 20 Volt/20W solar panel (field applications) or 24 V DC power supply (laboratory applications).
Communication is via a USB port or ICT wireless connectivity. The SMM logger is IP-65 rated and is controlled by a Windows and Mac driven GUI (Combined Instrument Software) or  complete logging solutions including look-up table, scripts and sensor calibration capabilities.

MP306 and MP406 soil Moisture sensors

For measuring volumetric soil moisture for scientific research, agriculture, soil mechanics and civil engineering. MP306 & MP406 use standing wave technology and do not need calibration and are not affected by temperature or

conductivity of the soil or material being measured. MP306 needles are arranged in a single plane for use in soil columns. The MP306 & MP406 can also be installed in the field, with a lifespan of 20+ years in the most extreme conditions.
