In the journey of agricultural modernization and research digitization, data precision determines the depth of research and the breadth of industry. The GT6 model, meticulously crafted by NiuBoL, is a flagship product designed specifically for universities, research institutes, and large agricultural institutions with extreme demands for detection accuracy.
GT6 not only breaks the time barrier of traditional laboratory testing but also compresses the performance of large precision photometers into a portable engineering case through multiple independent patented technologies. It is an integrated "mobile miniature laboratory" of reagents, instruments, and utensils, enabling rigorous scientific testing to seamlessly switch between field and laboratory anytime and anywhere.

GT6 possesses powerful soil analysis capabilities, providing a detailed "soil physical examination report":
Conventional Nutrients: Ammonium nitrogen, available phosphorus, available potassium, nitrate nitrogen, hydrolyzed nitrogen, total nitrogen, total phosphorus, total potassium.
Organic Matter and Carbon Balance: Supports both Tyurin method and extraction method for dual determination of organic matter, total organic carbon, and carbon-nitrogen ratio.
Medium and Trace Elements: Calcium, magnesium, sulfur, silicon, boron, iron, copper, manganese, zinc, chlorine, molybdenum, etc.
Physical and Chemical Properties: pH value (acidity and alkalinity), salinity (conductivity), moisture content.
Heavy Metal Early Warning: Monitoring of 10 heavy metals in soil including lead, arsenic, cadmium, chromium, mercury, nickel, aluminum, fluorine, titanium, selenium.

In response to quality control in the fertilizer market, GT6 provides a complete testing scheme from single-element to organic fertilizers:
Nitrogen-Phosphorus-Potassium Core Testing: Urea nitrogen, biuret, water-soluble phosphorus, organic fertilizer available nutrients, etc.
Humic Acid Specialization: Covers water-soluble and free-state humic acid in weathered coal, lignite, and peat.
New Fertilizers: Full nitrogen, total phosphorus, total potassium, and trace element determination for water-soluble and foliar fertilizers.
Nutrient Diagnosis: Real-time determination of nutrient abundance and deficiency in fresh crops and dried plants.
Food Safety: Rapid screening of nitrate, nitrite, and heavy metal residues in fruits and vegetables to ensure safety from farm to table.
Water Quality Monitoring: Extended support for nutrient and physical-chemical indicator testing of agricultural irrigation water.

1. Excellent Computing Architecture
GT6 adopts high-end ARM Cortex-A7 architecture and RK3288 quad-core processor with a main frequency of 1.88GHz. Powerful processing performance ensures ultra-fast response during multi-channel concurrent testing, paired with a customized Android intelligent system for smartphone-like smooth operation experience.
2. 12-Channel Patented Rotating Colorimetric Design
The instrument core adopts precision rotating colorimetric cell technology. Compared to traditional models, GT6 upgrades to 12 rotating detection channels, capable of quickly testing 10 samples at once. This design not only greatly improves throughput but also ensures optical path consistency between light source and sensor through physical rotation, eliminating mechanical wear and positioning deviation of traditional translation mechanisms.
3. High-Precision Filter Analysis Technology
Integrated with independent patented filter analysis method, equipped with high-performance cold light sources in red, blue, green, and orange wavelengths. High light source stability with no temperature drift during continuous operation, lifespan exceeding 100,000 hours, ensuring extreme precision with repeatability error ≤0.02%.
Expert-Level Fertilization System and Atlas
Formula Recommendation: Built-in national database of target yield fertilization schemes for more than 100 crops and fruit trees. After testing, simply input crop type and target yield, and the instrument automatically calculates recommended fertilization amounts.
Visual Diagnosis: Built-in high-definition standard atlas of crop nutrient deficiency, supporting intuitive nutrient abundance judgment through on-site leaf characterization.
Interactive Video Teaching
GT6 has embedded full-process videos for sample pretreatment and experimental operations. New personnel need not refer to thick manuals; just click the screen to follow the videos and complete the complete process from sampling, extraction, color development to comparison, greatly reducing the probability of human error.
Data Flow and Printing
Intelligent Printing: Built-in thermal printer can instantly generate complete reports including testing unit, personnel, project, absorbance, nutrient content (mg/kg), and QR code.
Cloud Backup: Equipped with USB interface, supports one-click data backup to U disk for convenient import to PC for long-term historical trend analysis.

Q1: What are the main improvements of GT6 compared to GT5 model?
GT6 is an advanced version for professional research-grade users. Main improvements include detection channels increased from 8 to 12, with in-depth optimization in optical stability, heavy metal detection accuracy, and system response speed. It is more suitable for scientific research requiring a large number of repetitive experiments and pursuing extremely low errors.
Q2: How reliable is heavy metal detection? Does it require complex digestion process?
GT6 has optimized optical algorithms for heavy metal detection with relative error controlled within 5%. Although there is a difference in absolute range compared to laboratory large atomic absorption spectroscopy (AAS), it has extremely high reference value for screening and trend monitoring. We provide supporting efficient extraction reagents to simplify digestion steps, more suitable for rapid decision-making.
Q3: What is the service life of reagents? How to purchase subsequently?
The supporting finished reagents provided by NiuBoL usually have a shelf life of about 1 year. Reagents are sealed in bottles for ready-to-use. Users can purchase standard reagent packs or special element reagents at any time through our official channels or local authorized distributors.
Q4: Can the instrument connect to a computer or export to Excel?
Yes. GT6 is equipped with USB communication interface. Users can copy detection results in digital format to U disk, then use common data analysis software (such as Excel) on PC for post-processing and chart drawing.
Q5: What to do if instrument battery is insufficient during field operation?
GT6 has AC/DC dual power supply mode. The built-in large-capacity lithium battery can support a full day's testing tasks (>10 hours). If power is low, you can directly connect to vehicle power through the randomly provided car charging cable to ensure uninterrupted experiments.
