Lutron's moisture content meter is different from a
conventional moisture meter. Sometimes certain materials can only be measured
via relative humidity inside the container (as long as there are no liquids or
extremely saturated material being analyzed). Plastics are a good example of
this. There are many materials where the RH is the only true way to get the
moisture content. A moisture meter uses 2 contacts to measure the resistance at
the exact place the probe is located. Great for spot checking, but does not give
the real picture of what the moisture is inside the bale, sack etc.
NOTE: This meter is used to measure the relative
humidity inside of a bale, bag, sack of grain, corn, rice, cotton, paper, hay, straw, tobacco, soil, compost etc.
Probe will get damaged when immersed in liquids &/or extremely saturated material.
