Soil NPK Tester and Soil pH Meter

  • Factory source Portable Soil Nutrient Tester Integrated NPK pH Conductivity Temperature Humidity Sensor

    Factory source Portable Soil Nutrient Tester Integrated NPK pH Conductivity Temperature Humidity Sensor

    The nutritive salt analyzer is our key research and development project achievement, developed by Frankstar. The instrument completely simulates manual operation, and only one instrument can simultaneously complete the in-situ on-line monitoring of five kinds of nutritive salt (No2-N nitrite, NO3-N nitrate, PO4-P phosphate, NH4-N ammonia nitrogen, SiO3-Si silicate) with high quality. Equipped with a handheld terminal, simplified setting process, and convenient operation. It can be deployed on the buoy, ship and other platforms.

    Frankstar in-situ nutrient sensor adapts established wet-chemistry methods into a fully automated, in-situ nutrient analyzer. The instrument strictly follows national standard detection protocols and accurately replicates manual laboratory procedures. Using precise reagent handling and automated reaction control, a single In-Situ Nutrient Sensor can simultaneously and continuously measure up to five key nutrients: nitrite (NO₂-N), nitrate (NO₃-N), phosphate (PO₄-P), ammonia nitrogen (NH₄-N), and silicate (SiO₃-Si).
