The AELAB TYS-B Chlorophyll Meter is designed to measure chlorophyll content in plant leaves and leaf temperature rapidly and precisely. Since chlorophyll and leaf nitrogen content have a strong correlation, the TYS-B model enables users to accurately assess nitrogen status and photosynthetic efficiency. It helps researchers and agronomists evaluate plant health and optimize nutrient management through non-destructive testing.
By integrating an advanced dual-wavelength optical system and silicon photodiode sensors, the AELAB TYS-B delivers stable and repeatable readings across diverse crop and vegetation types. This portable unit is suitable for in-field or laboratory use and supports comprehensive plant physiology studies.
The TYS-B features a durable handheld housing with integrated optical probes designed for precise leaf clamping. The measuring head employs a silicon semiconductor photodiode for reliable detection and a liquid crystal display (LCD) for direct SPAD and temperature readouts. Its 4.2 V – 2000 mAh rechargeable Lithium battery ensures extended field operation without performance loss.
The meter operates on a 2-wavelength concentration difference optical method. Light absorption at two specific wavelengths is analyzed to calculate relative chlorophyll concentration (SPAD value). Measurements are taken through a 2 mm × 2 mm optical area, and temperature compensation maintains accuracy between -10 °C and 50 °C. Results are displayed within 3 seconds and stored in internal memory.
The AELAB TYS-B supports data storage and average calculation directly on the device. Results can be manually recorded or transferred through standard data collection protocols for integration with agricultural analysis software. Designed under GLP-compatible principles, the meter ensures traceable performance and consistent analytical quality.
