We offer five different models of Digital Water & Soil Analysis Kits. This kit comprises of all types of advanced water and soil testing instruments. All our instruments are known for preciseness with which they check the pH, ORP, Conductivity, TDS, Salinity, Dissolved Oxygen, Turbidity and Temperature. The Water & Soil Analysis Kit (Model : VSI-06) : Six Parameters : Dissolved Oxygen, Oxidation Reduction Potential (ORP), pH, Total Dissolved Solids (TDS), Conductivity & Temperature. The Water & Soil Analysis Kit (Model : VSI-06D) : Four Parameters : Oxidation Reduction Potential (ORP), pH, Conductivity & Temperature. The Water & Soil Analysis Kit (Model : VSI-6D1) : Four Parameters : pH, Total Dissolved Solids (TDS), Conductivity & Temperature. The Water & Soil Analysis Kit (Model : VSI-06T) : Six Parameters : (Deluxe Model) : Dissolved Oxygen, pH, Total Dissolved Solids (TDS), Conductivity, Turbidity & Temperature. The Water & Soil Analysis Kit (Model : VSI-07) : Seven Parameters : Dissolved Oxygen, Oxidation Reduction Potential (ORP), pH, Total Dissolved Solids (TDS), Conductivity, Salinity & Temperature.
