Easy to operate and fast, with a complete set of accessories and finished reagents, it can be used out of the bottle without configuration.

Multiple functions and complete test items:

Soil nutrients: soil ammonium nitrogen, soil available phosphorus, soil available potassium, soil nitrate nitrogen, soil hydrolyzed nitrogen, soil total nitrogen, soil total phosphorus, soil total potassium, soil organic matter (Qiu Lin method), soil organic matter (extraction method), pH value, salt content, water content.

Test efficiency:

Multiple nutrients such as available N, P, K in the soil are extracted and determined at one time.

Test speed: Under normal proficiency, it takes 20 minutes to test three items of a soil sample (N, P, K) (including reagent preparation and soil sample pretreatment time), and it takes ≤40 minutes to test three soil samples (N, P, K) at the same time, and ≤1 hour to test 8 soil samples at the same time.
