Technical Specifications
LandMapper measures electrical parameters of soils and other
semi-solid media - electrical
resistivity (ER), conductivity (EC) and potential (EP).
Device is compact, portable and can be used for non-attended measurements (monitoring).
Measured parameters can be viewed on display as well as stored in internal non-volatile
memory.
Range of measurements…………………………ER= 0.1-1 106 Ohm m
………………… EC= 1 10-6 - 10 Sm-1
(ERM-04 only)……………………………………………EP= -1 to +1 V (0.01 mV)
User-selectable ER/EC/SP modes of measurement.
Error of measurements is typically less than 1%.
LandMapper automatically tunes to the range of measuring parameters for maximal
accuracy.
