F.A.Q.


What is a moisture meter?

A moisture meter is a precision instrument that measures changes in the material's capacitance which vary with the moisture content. The instrument emits a high frequency signal. The frequency of the electrical signal will vary due to the capacitance of the material.

How does a moisture meter operate?

Most probe-type meters operate on the principle of electrical resistance, utilizing the relationship between the moisture content of the material and its conductivity. This relation is possible because moisture is an effective conductor of electricity and hay acts as an effective insulator. The "reading" is made between the two metal contacts at the tip of the probe.

What affects the meter readings?

Besides Moisture content, factors which affect meter readings most are: Moisture distribution, crop variety, temperature of the hay, crop maturity, sample density, cutting, and the overall climatic conditions present. Cloud cover and high relative humidity result in more variable Moisture readings than a sunny, dry day with light breezes.

How can i know i'm receiving the most accurate results?

Because field conditions can change rapidly, accuracy guidelines must be considered in terms of "ranges", not specific points. Claims of accuracy should be taken with caution, because it is unlikely that such claims can be consistent. Expert evaluations of the same meter may yield different results, mainly dependent on the technician’s sampling procedure, conditioning and uniformity of the samples, difference in crop, and differences in oven test procedure. For optimum results, carefully read the owners manual provided with each meter.

Is there a way to make sure my meter is in calibration?

The primary or electrical calibration of the tester can easily be checked by the built-in calibration checkpoint feature or by using an optional Moisture content standard.

How do I keep a moisture meter in good working condition?

Moisture Meters are well known for their ruggedness and ability to withstand years of rough handling. Like any testing instrument, a little care goes a long way toward trouble-free service:

  • Store the meter in clean, dry place
  • Change batteries and pins as needed
  • Keep the meter and electrode clean by using any biodegradable cleanser sparingly on external parts only.
