IIISoil measuring instrumentTest speed:
Can simultaneously detect 8 samples;
Test one soil sample (N, P, K) for ≤ 30 minutes, and simultaneously test three soil samples (N, P, K) for ≤ 40 minutes;
Measure one fertilizer (N, P, K) for ≤ 50 minutes, and simultaneously test three soil samples (N, P, K) for ≤ 1.5 hours.
4、 Product Instrument Features:
The soil nutrient rapid analyzer integrates medicine, equipment, and instruments, making it easy to carry and equivalent to a small laboratory. Suitable for agricultural service departments or agricultural material distributors, fertilizer manufacturers to conduct soil testing and fertilization, and to identify the authenticity of fertilizers.
Easy to operate and fast, the finished medicine can be used immediately after opening the bottle, without the need for configuration.
Reliable performance: The working stability is 6 times better than the national standard JJG179-90 index, and the repeatability reaches the level of the grating spectrophotometer index

5、 After sales service:
The soil nutrient rapid analyzer comes with a one-year warranty for the entire machine (with a five-year warranty for the main unit), lifetime maintenance services, shipping of the instrument, and free training.
Provide free agricultural related technical support such as soil and fertilizer!
