측정항목
전기전도도(Electrical conductivity), 상대유전율(relative dielectric permittivity), 용적 수분함량(volumetric water content), 토양온도

------------------------------------------------------------------------------------------------------------------------------------------------
측정범위
- 전기전도도 : Solution EC 0 ~ 8 dS/m, Bulk EC 0 ~ 8 dS/m

- 상대 유전율 : 1 ~ 81

- 용적 수분함량 : 0% 100% (with M4! SDI-12 command)

- 온도 : -50 ~ +70℃

------------------------------------------------------------------------------------------------------------------------------------------------
정확도

- 전기전도도 : ±(측정값의 5%+0.05 dS/m)

- 상대 유전율 : ±(측정값의 3%+0.8) @1 ~ 40 for solution electrical conductivity ≤8 dS/m

                    ±2 @ 40 ~ 81 for solution electrical conductivity ≤2.8 dS/m

- 용적 수분함량 : ±1%(with soil specific calibration), 

    ±3% (typical with factory VWC model) where solution EC<10 dS/m)

- 온도 : ±0.5℃(for typical soil temperatures [0 ~ 40℃] when probe body is buried in soil)

 ±0.5℃(for full temperature range)
