The Plant Nutrition Analyzer TYS-4N is a handheld, non-destructive leaf analyzer that measures four key plant health indicators simultaneously—chlorophyll content (SPAD), leaf surface temperature, leaf surface humidity, and nitrogen content—without interrupting plant growth or damaging the tissue being tested. A 2 mm × 2 mm measurement aperture and a 2-second interval make it practical for rapid, high-throughput field and greenhouse sampling.
Accuracy is maintained through multi-point, multi-stage calibration, and the built-in leaf chamber incorporates a multi-layer anti-interference design that shields measurements from ambient light and environmental temperature variation—two common sources of error in portable optical leaf instruments.
Data management is straightforward: the onboard OLED display shows real-time readings along with the average, maximum, and minimum of the last 30 measurement sets, and the unit stores up to 2,000 records locally. Bluetooth connectivity pairs the analyzer with a mobile app for real-time synchronization and unlimited cloud-side storage, keeping large-scale crop monitoring studies organized without manual transcription.
Powered by two standard 1.5 V batteries rated for up to 5,000 continuous measurements, the TYS-4N is suited for agronomic research, horticultural trials, precision-farming nutrition assessments, and plant physiology studies where rapid, in-situ leaf analysis is required. A 20% low-battery alert ensures the instrument never shuts down unexpectedly mid-sampling session.

What parameters does the TYS-4N measure, and what are their measurement ranges?
The analyzer measures four parameters in a single clip: SPAD (relative chlorophyll content) from 0 to 50 SPAD units, leaf surface temperature from 10 °C to 99.9 °C, nitrogen content from 0.0 to 99.9 mg/g, and leaf surface humidity from 0.0 to 99.9 %RH.
How accurate are the readings?
Leaf surface temperature accuracy is ±0.5 °C (±0.2 °C for SPAD-mode temperature readings), nitrogen content accuracy is ±0.5 units, leaf surface humidity accuracy is ±5 %RH, and nitrogen content repeatability is within ±5%. Multi-point, multi-stage calibration is applied to maintain these tolerances across the full measurement range.
Will using the analyzer harm the leaves or affect plant growth?
No. The TYS-4N uses a non-destructive optical measurement method, so leaves are not damaged and normal plant growth is unaffected. This makes it suitable for repeated measurements on the same leaf or plant over the course of a study.
How much data can the instrument store, and can I export readings to a computer or phone?
The instrument stores up to 2,000 measurement records onboard. Via built-in Bluetooth, it connects to a companion mobile app that provides real-time data synchronization and unlimited additional storage. The display also shows the average, highest, and lowest values across the last 30 measurement sets for quick in-field review.
What are the leaf thickness and measurement area requirements, and how long does each measurement take?
The leaf chamber accommodates leaves up to 1.2 mm thick. Each measurement is completed within a 2-second interval, and the active sensing area is 2 mm × 2 mm, allowing precise targeting of specific leaf regions.
