TPY Series Soil Nutrient Tester

Soil Nutrient Tester is also called Soil NPK Tester or Analyzer, which is available to test nutrient content, such as soil pH, salinity, moisture in soil. This analyzer for testing soil nutrinet is adaptable used with chemical reagent.


1.  Quickly test the N, P, K, organic matter, salinity, and pH in soil

2.  With the function of time display, can automatically record and save the time of tested sample.

3.  Large capacity storage (time, place, fertilizers), datum can be checked at any time

4.  Print testing date, sample number, sample items, sample contents, variety and so on

5.  Big-screen LCD shows, and will guide you how to operate.

6.  Can set crop variety, crop yield, fertilizer variety, and automatically count the fertilizing amount.

7.  The reagent included: low requirement to the storage condition, last longer, and low test cost.
