🌾 Agricultural Field Testing Reviews

⭐⭐⭐⭐☆ Amina Diallo - Agricultural Consultant
"Used this during harvest season to test fruit sugar levels across multiple farms. The portability and rugged build made it ideal for field conditions. Took it through rain, dust, and constant transport—no issues. Only reason I’m not giving 5 stars is that the sample holder could be slightly larger for pulpy samples, but the adjustable feature helps compensate."
