Em38 ground conductivity meter operating manual

Electromagnetic (EM) Ground Conductivity Meters. Electromagnetic survey technology is a proven non-invasive method for measuring the apparent electrical conductivity of the ground from the surface to varying depths depending on project objectives. JDMA staff have experience using the Geonics EM31, EM34 and EM38 instruments. The EM31 explores to 6m depth, the . 1. Apparent conductivity in millisiemens per meter (mS/m) 2. In-phase ratio of the secondary to primary magnetic field in parts per thousand (ppt) INTERCOIL SPACING: 1 and meters OPERATING FREQUENCY: KHz MEASURING RANGE: Conductivity: mS/m In-phase: ± 29 ppt for 1 m In-phase: ± 7 ppt for m MEASUREMENT RESOLUTION: ± % .
