Product Function FAQs

1. What are the advantages of YT‑YB non‑destructive live‑plant detection?Based on dual‑wavelength spectral absorption, the meter requires no leaf picking and causes zero damage, enabling continuous monitoring throughout the growth cycle. Traditional devices destroy samples and cannot track long‑term changes. YT‑YB enables in‑situ real‑time monitoring, especially for breeding materials, rare plants, and long‑term experimental fields, providing reliable data for precise fertilization and research.

2. What is the practical value of simultaneous chlorophyll and leaf temperature measurement?One operation displays and stores both parameters, doubling efficiency. Chlorophyll reflects nitrogen nutrition and photosynthesis; leaf temperature indicates water and stress status. Together they judge crop health more accurately than single parameter. For field management, scientific research, and stress research, dual‑parameter detection reduces error and saves time.

3. How does 16GB large grouped storage meet data management needs?16GB stores hundreds of thousands records with grouping by crop, plot, growth stage, or treatment. Users can view history and delete anomalies directly on the meter without a computer. It satisfies long‑term data storage for experiments, base records, and ecological monitoring with complete security.

4. What convenience does the dual‑function USB interface provide?The USB port supports data transfer and charging with one cable. Data can be exported directly to a computer without professional software, compatible with Excel. It can also be charged via car charger or power bank. Compared with traditional devices needing separate chargers, YT‑YB reduces accessories and improves convenience.

5. What advantages does the high‑contrast LCD offer outdoors?The high‑contrast LCD screen clearly displays data even in strong sunlight without shading. Stable display avoids glare and fatigue, suitable for long‑term field sampling. Large, clear figures reduce misreading and improve accuracy and efficiency.

6. Why are low power and overcharge protection important?Low power design with 3000mAh battery supports all‑day outdoor use. Built‑in overcharge protection extends battery life and reduces replacement costs. Ultra‑low standby power ensures long‑term storage without power loss. These designs improve reliability and reduce long‑term costs.

Operation FAQs

1. How can new users quickly operate the YT‑YB Chlorophyll Meter?Turn on the machine, insert a leaf into the slot, close the probe; the meter automatically reads in <0.8 seconds and stores data. Users can view history, delete anomalies, and switch languages easily. USB connects directly to computers. Most users master basic operation in 5 minutes and full functions in 30 minutes.

2. What is the standard field measurement process and precautions?Turn on → wipe leaf → place in center → close and read → auto‑save.
