hi
can we use one set of metal detection test pieces for similar products but different weights .
we use 3.5 ferrous. 4.5 non ferrous and 5.0 s/steel
the product are low moisture <14% and most of them are blended seasonings some have higher salt levels then others .
we pack the product in 25kg packs and currently use the above test pieces ,my question is can i use the same test pieces or would i have to carry out sensitivity checks on 16kg and 10kg ?
and how would i do this please ( i am very new to metal detection so not sure )
thanks in advance
