Smart pH/EC/TDS combined monitor

3 Meters in one. This meter allows you to measure pH, EC, and TDS with just one instrument and one single probe. It comes with a conductivity range that goes up to 6.00mS/cm, and a TDS up to 4000 ppm. It is ideal for testing in crop production. Soil and water well pH that is too acidic or alkaline can have an adverse effect on plant nutrition and water uptake and directly effects the efficiency of fertilizer, herbicides and pesticides. Supplied with a MA850 interchangeable probe to measure pH, conductivity and TDS. It also comes with a 9V battery and 20 ml of sachet buffer solution of pH 7.01, 1500 ppm and 1.413 µS/cm. The pH electrode utilizes a fiber junction to reduce contamination when measuring fertilizer solutions. It is calibrated manually. Range 0.00 to 14.00 pH. Range 0 to 4000 ppm EC. Range 0.0 to 6.00 µS/cm for TDS. The accuracy is +/- 0.2 pH, and a +/- 2% full scale for EC and TDS.

Refractometer

$refractometer box$

Within a given species of plant, the crop with the higher refractive index will have a higher sugar content, higher mineral content, and a higher protein content. This adds up to a sweeter tasting, more minerally nutritious food with a lower nitrate and water content and better storage characteristics. A broad generalization: produce over 12 BRIX is considered good because crops above this value are usually not bothered by insects or diseases. Range of 0-32 % BRIX, resolution of 0.1%. Units come with a fruit and vegetable reference table.
