Refractometer - Is the honey Grade A?

To sell honey it has the be Grade A.
Grade A honey is defined as: it has to taste like honey and the moisture has to be
18.6% water content or less.
 To find out the water content of honey it needs to be measured with an instrument called a refractometer. A refractometer takes a small sample of honey covering the lens of the instrument. Light passing through the instruments lens refracts the light and the result is read on a scale the user sees by looking through the eyepiece.
 My preference is a light reading refractometer with a thermometer for temperature compensation. It is accurate and easy to use. All refractometers need to by calibrated when new and periodically after that. Calibration is done with a sample of liquid that has a predetermined set point and adjustments are made to this scale.
 Some refractometers are digital, some are light reading. There are many scales of measurement in different industries. Beekeepers use a refactometer with a honey scale. With any instrument you get what you pay for. Refractometers range in price from $75 - $400.
 Here at Nature's Nectar LLC we check honey samples for free. Please no more than three samples at a time. Always bring a full container for a sample. The sample should be free of wax and we only need a thimble size for the sample.

Refractometer, the plastic cover is raised and honey is put on the purple lens

This is the scale inside the eye piece. This sample is reading 19.5%. There is a thermometer on the bottom of this instrument for temperature compensation. The thermometer read to take off 1% of the scale reading. So this sample of honey is 18.5% moisture content and is Grade A honey.
