HM-T1 Desktop Soil Nutrient Analyzer

Product Overview

The HM-T1 Desktop Soil Nutrient Analyzer is a 12-channel spectrophotometric testing instrument engineered for routine agricultural soil fertility testing and formula fertilization. Powered by an ARM Cortex-A7 quad-core processor and Android OS, the HM-T1 integrates optical analysis, touch-controlled workflow, automated calculations, and thermal printing into a self-contained desktop workstation for agricultural service stations, farm cooperatives, and fertilizer dealers.

Featuring a 4-wavelength cold light source and patented filter technology (Patent ZL 2020 2 1763837.9), the HM-T1 completes simultaneous extraction and determination of available nitrogen, phosphorus, and potassium (NPK) in 20 minutes per sample, or 8 samples per hour. Built-in fertilization recommendation algorithms and a plant deficiency visual atlas provide immediate field guidance.

Key Features

• 12 optical colorimetric channels enable simultaneous batch testing of 12 samples, improving laboratory throughput.
• 4-wavelength cold light source (680nm, 420nm, 510nm, 590nm) delivers over 100,000 hours of operating life without thermal drift.
• Patented optical filter technology ensures measurement consistency certified by the National Institute of Metrology.
• 7-inch true-color capacitive touchscreen (1024×600) with intuitive Android UI minimizes operational training time.
• Built-in thermal printer outputs test receipts with operator ID, channel number, absorbance, nutrient concentrations, and QR codes.
• Integrated expert fertilization system calculates nutrient application rates for over 100 agricultural crops and fruit trees.
• Plant nutritional deficiency atlas enables direct on-screen leaf symptom comparison to diagnose nutrient disorders.
• Wireless data connectivity (WiFi, 4G, GPRS) uploads testing records to the smart agricultural cloud platform.
• Dual AC/DC power with internal rechargeable lithium battery providing over 10 hours of continuous field operation.
• IP65 ingress protection, multi-user passwords, automatic power-off data protection, and GPS coordinate tagging.

Applications

The HM-T1 is designed for standard agricultural soil nutrient determination and fertility mapping:

• Soil Available Nutrients: Ammonium nitrogen, available phosphorus, available potassium, nitrate nitrogen, hydrolyzed nitrogen.
• Soil Total Nutrients & Organic Matter: Total nitrogen, total phosphorus, total potassium, organic matter, TOC, and C/N ratio.
• Physical and Chemical Properties: Soil pH value (1–14), soil salt content (0.01%–1.00%), and soil moisture (0–100%).
• Target Facilities: Agricultural extension stations, rural cooperatives, fertilizer retail outlets, and commercial plantations.
