These standards can be used to not only ensure that your handheld meters are functioning correctly but to test calibration factors applied to measurements taken on core over a range of values. 

The standards can be purchased individually or as a box set.  The box set has a number of conductivity and susceptibility standards designed to test the range of your handheld instrument.

Cost – $280 each or $1120 + GST for a box set of 6 (3 x magnetic susceptibility, 3 x conductivity)

Standards are available through Terra Petrophysics or GeoRESULTS (www.georesults.com.au)
