EC meter styles
The two most common hand held electrical conductivity meter probe designs are illustrated in this photo. The two probes on the left were designed for use in water suspensions of salts by measuring conductivity of electrons between the two metal rods at the tip of the probe. The sensor on the right (Spectrum Field Scout EC meter) was designed to be used by directly probing saturated soil or potting mixtures. When direct measurements are made in soil with either probe design, resistance caused by the soil particles must be taken into account. PACE provides several conversion tables (
Spectrum Field Scout conversion)to aid in estimation of soil saturated paste extract salinity.
