A refractometer measures the Brix level (sugar content) of a substance. The VeeGee refractometer is a simple fuel gauge for your crop. It is durable and has an all metal design. By looking through the eye piece you will notice that the refractometer has a high quality optical glass prism that helps make your reading as clear as possible. A rubber grip that is dimpled helps ensure a simple external cleanup.
The penetrometer is a gauged probe used to measure the level of compaction at various levels within the soil. As soil becomes more compacted, it loses its ability to absorb and retain moisture. The soil pressure in the aerobic zone (with oxygen) should not exceed 300 PSI (pounds per square inch). This is where the feeder roots of most plants exist and they are unable to penetrate higher levels of pressure. The anaerobic zone (without oxygen) is where the soil loses its ability to drain water and can no longer pull fresh oxygen in.
The Milwaukee MW302 is a cost effective and reliable meter used for measuring electroconductivity (EC) in the soil. A 'slurry' mixture is required for this unit, which consists of equal part of soil mixed with distilled or deionized water. The MW302 comes with a sturdy carrying case, calibration solutions and a measuring cup for mixing.
The Spectrum FieldScout is a direct soil meter used for measuring electroconductivity. This feature offers accuracy and convenience. The FieldScout has a patented paired sensor tip which provides maximum soil-sensor contact and higher accuracy and automatic temperature compensation. This meter includes a sturdy carrying case and calibration solution.
