HM-T2 Multifunctional Soil Nutrient Analyzer

Product Overview

The HM-T2 Multifunctional Soil Nutrient Analyzer is an enhanced 12-channel soil testing workstation designed to combine standard macronutrient testing with comprehensive soil micronutrient diagnostics. In modern horticulture and crop production, yields are frequently limited by secondary and micronutrient imbalances. The HM-T2 provides a balanced diagnostic approach by testing soil NPK, organic matter, and 11 essential medium and trace elements.

Driven by an ARM Cortex-A7 RK3288 processor and Android OS, the HM-T2 utilizes high-precision optical filter technology (Patent ZL 2020 2 1763837.9) and 4-wavelength cold light sources across all 12 channels. Pre-programmed calibration algorithms allow technicians to identify trace mineral deficiencies before visual symptoms occur in the field.

Key Features

• Multi-parameter testing covers soil NPK, organic carbon, pH, salinity, and 11 trace elements (Ca, Mg, S, Si, B, Fe, Cu, Mn, Zn, Cl, Mo).
• 12 parallel optical colorimetric channels support simultaneous multi-sample testing, accelerating laboratory workflows.
• 4 stable cold light wavelengths (680nm, 420nm, 510nm, 590nm) with over 100,000 hours of operating life and zero thermal drift.
• Authoritative optical calibration recognized by the National Institute of Metrology, delivering ≤0.03% repeatability error.
• 7-inch true-color capacitive touchscreen with intuitive graphical interface, multi-account management, and USB export.
• Plant nutritional deficiency atlas provides side-by-side on-screen comparison of leaf deficiency symptoms.
• Crop fertilization expert system calculates balanced prescriptions incorporating macronutrients and micronutrient amendments.
• Built-in thermal printer produces immediate test receipts recording sample ID, nutrient concentrations, and QR codes.
• Multi-channel wireless synchronization (WiFi, 4G, GPRS) connects testing logs to the smart agricultural cloud platform.
• Hybrid power architecture supporting AC 220V mains, internal rechargeable lithium battery (>10h), and 12V vehicle charging.

Applications

The HM-T2 is suited for comprehensive soil fertility audits, orchard management, and protected horticulture:

• Soil Macro Nutrients: Ammonium nitrogen, available phosphorus, available potassium, nitrate nitrogen, hydrolyzed nitrogen, total NPK, organic matter, TOC, and C/N ratio.
• Soil Trace Elements: Calcium (Ca), magnesium (Mg), sulfur (S), silicon (Si), boron (B), iron (Fe), copper (Cu), manganese (Mn), zinc (Zn), chlorine (Cl), and molybdenum (Mo).
• Physical-Chemical Parameters: Soil pH (1–14), soil salt content (0.01%–1.00%), and soil moisture (0–100%).
• Target Facilities: Commercial plantations, greenhouse vegetable bases, agricultural testing labs, and specialty fertilizer centers.
