Product Overview
The HM-T3 Comprehensive Soil and Fertilizer Quality Tester is engineered for fertilizer manufacturing plants, agricultural quality supervision stations, and commercial compost operations requiring rigorous input verification. In agricultural supply channels, substandard fertilizers containing deficient nitrogen, unreactive phosphates, or excessive biuret cause crop damage and financial loss. The HM-T3 provides rapid quantitative testing to authenticate raw materials, monitor granulation, and verify finished products.
With an optical repeatability error of ≤0.02% and stability exceeding national standard JJG179-90 by sixfold, the HM-T3 enables chemists to test a single fertilizer sample for total NPK within 50 minutes. The instrument handles primary fertilizer categories—including nitrogenous, phosphatic, potassic, compound, organic composts, humic acid formulations, and water-soluble fertilizers—alongside comprehensive soil fertility audits.
Key Features
- Specialized analytical suite for fertilizer quality control, capable of testing elemental, compound, organic, and liquid fertilizers.
- Fast testing efficiency: full NPK analysis of a single fertilizer sample in ≤50 minutes; 3 samples tested concurrently in ≤1.5 hours.
- Analytical precision meets inspection standards with repeatability error of ≤0.02% and Metrology Calibration Certificate.
- 12 parallel testing channels allow quality technicians to run multiple fertilizer production batches simultaneously.
- Specific procedures detect biuret in urea, water-soluble phosphate fractions, and free humic acid content.
- Android-based 7-inch touchscreen terminal provides pre-installed video demonstrations of chemical digestion procedures.
- Integrated thermal printer immediately outputs inspection certificates recording batch number, nutrient percentages, and QR codes.
- Telemetry options (WiFi, 4G, GPRS, USB, RJ-45) securely upload test data to corporate ERP or regulatory cloud networks.
- Combined soil and plant tissue testing capability allows companies to correlate fertilizer application with crop uptake.
- Rugged IP65 design with internal rechargeable battery (>10h continuous runtime) enables laboratory and mobile field testing.
Applications
The HM-T3 provides analytical capabilities across fertilizer quality assurance and regulatory settings:
- Fertilizer Manufacturer Quality Assurance: In-process screening of raw ingredients and final inspection of finished compound blends.
- Organic Fertilizer & Compost Verification: Quantitative determination of total NPK, organic matter, and humic acid fractions.
- Market Supervision: Fast screening of commercial fertilizer products to protect farmers against fraudulent nutrient claims.
- Crop Response Tracking: Analyzing plant tissues, tobacco leaf nutrient balances, and irrigation water to evaluate fertilizer efficiency.
