Overview
The TFC-ZNS-I soil and fertilizer tester can set crop varieties, crop yields, and fertilizer varieties according to local conditions, and automatically calculate the amount of fertilizer applied. It can detect the content of available nitrogen, available phosphorus, available potassium, organic matter, soil pH, and soil salt in samples such as soil, plants, chemical fertilizers, and biological fertilizers.
Product Details
★ Crop varieties, crop yields, and fertilizer varieties can be set according to local conditions, and the fertilizer application amount can be automatically calculated.
★ Adopting LCD Chinese large screen backlight display, Chinese menu prompts for operation, immediately visible.
★ It can detect the content of available nitrogen, available phosphorus, available potassium, organic matter, soil pH, and soil salt in samples such as soil, plants, chemical fertilizers, and biological fertilizers.
★
| The rotating colorimetric testing device can simultaneously test multiple samples. This instrument has an automatic charging function and can be used for both AC and DC. It can be used for field flow testing. The instrument host comes with a built-in micro printer, which can print out the test result data through this machine. | Measurement project | |
