Product Quick Reference Card

Product Notes

The SMR101A measures Volumetric Water Content (VWC) over a range of 0 to 100%. The

system can be used in for most soil types as well as soil-less media with minimal salinity

and textural effects.

EC Probe Soil Insertion

Refer to the “ECHO Probe Insertion Guide” application note on the MadgeTech website for

instructions on how to insert the probe into the soil.

Calibrating Soil Moisture Probes

Refer to the “Calibrating ECH20 Soil Moisture Probes” application note on the MadgeTech

website for information on how to calibrate the probe.

Additional Information

The following application notes can be downloaded from the website:

• Response of the ECH20 Soil Moisture Probe to variation in the water content, soil type,

and solution electrical conductivity.

• Measuring water content in organic soils using ECH20 probe.

LEDs

- Green LED: every 10 seconds to indicate logging and 15 seconds to indicate delay start

mode.

- Red LED: every 10 seconds to indicate low battery and/or memory and 1 seconds to

indicate an alarm condition.

Multiple Start/Stop Mode Activation

To start device: Press and hold the pushbutton for 5 seconds, the green LED will flash during

this time. The device has started logging.

To stop the device: Press and hold the pushbutton for 5 seconds, the red LED will flash during
