Product Overview
The HM-T1 Soil Nutrient Tester is designed for agricultural service stations, farming cooperatives, and fertilizer distribution networks where rapid batch soil testing and field recommendations are required. During seasonal planting periods, agricultural technicians must evaluate multiple soil samples quickly. The HM-T1 addresses this requirement with a 12-channel colorimetric design that completes simultaneous soil NPK testing for up to 8 samples within 60 minutes.
Featuring a rugged IP65 chassis with an integrated 7-inch Android interface, the HM-T1 combines field durability with clear video-guided workflows. Operators can follow on-screen tutorial videos to execute soil preparation and color development. Test results automatically link with the built-in fertilization expert database to generate scientific recommendations on site.
Key Features
- 12 parallel colorimetric wells handle seasonal soil testing demands without laboratory delays.
- Simultaneous extraction chemistry allows soil available NPK to be extracted together, completing tests in under 20 minutes per batch.
- Android-powered touchscreen preloaded with video tutorials, enabling fast training for new operators.
- Expert fertilization database covers over 100 crops and fruit trees, calculating fertilizer quantities from target yields.
- Built-in thermal printer outputs immediate test receipts with QR codes for transparent record-keeping.
- Dual AC 220V power and internal rechargeable lithium battery ensure continuous operation during mobile field work.
- Cloud connectivity via WiFi, 4G, and GPRS synchronizes field test logs for regional soil fertility mapping.
- Self-contained accessory cases include precision balance, pH pen, salinity pen, glassware, and ready-to-use reagents.
Applications
The HM-T1 supports agricultural soil fertility testing across varied crop environments:
- Routine Field Testing: Available nitrogen, available phosphorus, available potassium, organic matter, soil pH, and salinity.
- Formula Fertilization: Field-specific fertilizer recommendation cards for grains, oilseeds, vegetables, and orchard crops.
- Agricultural Retail Services: Assisting fertilizer retailers in recommending balanced fertilizer blends based on test data.
- Cooperative Soil Auditing: Periodic fertility monitoring across cooperative acreage and family farm holdings.
