★ Resolution: 0.001, touch sensitive buttons, built-in next-generation thermal printer, capable of printing test results.

The compound fertilizer nutrient content detector can detect the content of available nitrogen, available phosphorus, available potassium, total nitrogen, total phosphorus, total potassium, organic matter, acidity and alkalinity, various trace elements such as calcium, magnesium, sulfur, iron, manganese, boron, zinc, copper, chlorine, silicon, molybdenum, as well as heavy metals such as lead, chromium, cadmium, mercury, arsenic, nickel, aluminum, fluorine, titanium, selenium, etc. in fertilizers, organic fertilizers (including foliar fertilizers, water-soluble fertilizers, and spray fertilizers), and biological fertilizers.

★ Adopting high brightness LED light source and filter processing to ensure stable wavelength of the light source, silicon semiconductor is used as the signal receiving system with a lifespan of up to 100000 hours. The light source is stable, with good reproducibility and high accuracy.

The colorimetric groove adopts a single channel design, with no mechanical displacement or wear. The optical path testing positioning is precise, ensuring the accuracy of the measurement results.
