HI Folks,

Just picked up a damp tester from Aldi.What do you guys think of these meters and are they accurate and do you need to pierce wall board or is contact sufficent to get reading

hi dona

i got one the other day to check on the van you do need to pierce the wall board but not all the way in (just the very tips) yes i think they are accurate i try'd mine on a piece off wet wood in the garden then had ago with a friends £45 meter and both readings where with in 002% off each other.but you must do the calibration to 100 before useing.

hope this helps jcbdigger
