Product Overview
The HM-T2 Soil and Trace Element Analyzer is engineered for commercial orchards, greenhouse vegetable facilities, and cash crop growers addressing physiological disorders caused by trace element imbalances. Sensitive crops such as citrus, grapes, apples, tomatoes, and greenhouse ornamentals often display physiological stress (such as chlorosis or blossom-end rot) due to micronutrient shortages. The HM-T2 delivers rapid testing to identify and correct these deficiencies.
Featuring 12 optical channels and pre-calibrated test protocols, the HM-T2 enables technicians to measure available NPK, organic matter, and 11 trace elements (Ca, Mg, S, Si, B, Fe, Cu, Mn, Zn, Cl, Mo) directly on site. The integrated deficiency atlas supports direct comparison between leaf symptoms and reference deficiency images, connecting chemical data with field practices.
Key Features
- Specialized for high-value agriculture, simultaneously analyzing soil NPK, organic fertility, and 11 essential trace elements.
- 12 parallel optical test wells streamline testing across extensive orchard and greenhouse grid samplings.
- Pre-calibrated photometric routines for calcium, magnesium, sulfur, boron, iron, zinc, and manganese eliminate manual calibration curves.
- 7-inch Android touch screen displays the plant deficiency standard atlas for immediate symptom differentiation.
- Integrated formula fertilization module calculates targeted micronutrient applications to correct identified deficits.
- High-accuracy optical filter technology ensures reliable trace-level detection sensitivity certified by metrology authorities.
- Immediate report printing via the built-in thermal printer provides documentation and recommendations on site.
- Wireless data transfer (WiFi, 4G, GPRS) uploads field records to cloud databases for GIS nutrient mapping.
- Portable desktop form factor with dual AC mains and internal rechargeable lithium battery (>10h continuous runtime).
Applications
The HM-T2 supports specialized soil diagnostics across commercial agriculture:
- Commercial Fruit Orchards: Measuring soil available calcium, magnesium, iron, zinc, and boron to mitigate physiological disorders.
- Greenhouse Horticulture: Monitoring secondary salinization, organic matter, and micronutrient availability under continuous cropping.
- Cash Crop Estates: Fertility audits in tea gardens, coffee plantations, tobacco fields, and berry farms requiring balanced nutrition.
- Agronomic Advisory: Equipping field consultants to deliver fast soil nutrient assessments and custom micronutrient formulas.
