Product Overview
The HM-T4 Soil Heavy Metal and Food Safety Nutrient Analyzer is an environmental and agro-product testing platform engineered for university laboratories, environmental monitoring agencies, produce safety inspection stations, and organic food certification bodies. In sustainable agriculture, soil fertility must be evaluated alongside environmental safety: heavy metal contamination in farmland soils translocates into food crops, presenting public health risks. The HM-T4 provides an analytical link connecting soil contamination assessment with edible crop safety certification.
Designed with 12 optical channels, patent-certified filter spectrophotometry (Patent ZL 2020 2 1763837.9), and optical repeatability of ≤0.02%, the HM-T4 quantitatively screens heavy metals in soils and organic fertilizers alongside nitrate, nitrite, and heavy metal contaminants in fresh fruits and vegetables. Featuring GPS coordinate recording, portable dual power modes, and thermal printing with verification QR codes, the HM-T4 empowers field teams to trace contamination sources.
Key Features
- Dual-focus testing connecting soil heavy metal pollution screening with produce food safety compliance in a single workstation.
- Toxic metal screening quantifies lead (Pb), arsenic (As), cadmium (Cd), chromium (Cr), and mercury (Hg) in farmland soils and crops.
- Food safety testing module measures nitrates and nitrites in fresh vegetables and fruits to prevent dietary risks.
- Scientific research-grade analytical precision with optical repeatability error of ≤0.02%, certified by metrology authorities.
- 12 parallel optical colorimetric channels maximize testing throughput during field environmental audits and produce inspections.
- 4-wavelength cold light source system (680nm, 420nm, 510nm, 590nm) delivers over 100,000 hours of drift-free illumination.
- 7-inch Android touchscreen terminal includes full sample preparation and color development video walkthroughs.
- Built-in GPS receiver tags latitude and longitude coordinates to testing records during field soil contamination mapping.
- Integrated thermal printer generates instant compliance receipts displaying testing location, operator, nutrient values, and QR codes.
- Seamless data connectivity via WiFi, 4G, and GPRS transfers testing logs to regional environmental databases.
- IP65 ruggedized casing with dual AC 220V / internal lithium battery power (>10h continuous operation) and 12V vehicle charging.
Applications
The HM-T4 serves analytical demands spanning environmental protection, agronomy, and public food safety:
- Farmland Environmental Audits: Screening industrial fringe soils, mining areas, and irrigation zones for heavy metals (Pb, As, Cd, Cr, Hg).
- Produce Safety Screening: Testing nitrate and nitrite residues and heavy metal content in fresh commercial vegetables and fruits.
- Organic & Green Food Certification: Conducting soil baseline audits and finished product contaminant verification for eco-certified bases.
- Academic & Research Fieldwork: Supporting university agronomy departments and research institutes in environmental remediation projects.
