Handheld Spectrometer

Handheld Spectrometer
It is focused on achieving the demands of agricultural field.
The Sensor head conforms with the JIS AA Class and DIN B Class Illumination requirements. Overall, the measuring process has a high speed, accuracy and stability.
It is recommended for the horticultural Factory , Green house and City farmers. The plant growth's success formula -PPFD (photosynthetic photon flux density) What is PPFD?
It means how many photons hit a defined area in one second.
PPFD is the unit of measure, defined by μmol/m2/s or micro-moles of photons falling on a square meter per second.
Plant has various species and different categories which have different PPFD requirements.
Normally, Photosynthetically available Radiation (PAR) wavelength is 400nm-700nm.
The light intensity has valuable effects on the plant due to the different wavelengths. ●Blue light (400nm-500nm)- High absorption of chlorophyll and carotenoids influences the photosynthesis greatly.
●Green light (500nm-600nm)- Low absorption by pigments.
●Red light (600nm-700nm)- Improving plant flowering and germination.
●UV light (400nm↓)- Inhibition of plant growth but good for plant pigment generation.
●FR light (700nm↑)- Adjustments of flowering and germination.
Users can easily understand the environmental requirement of plant growth and
adjust the artificial light clearly through the PPFD & PFD UI.
Ensure the horticulture high production, safety and achieve the scientific, intelligent cultivation environment. Multiple measuring choices and unlimited space and distance.
Real time detection and gathering the data which improve the measuring efficiency and flexibility. Free Downloadable APP- Android, iOS and PC uSpectrum Software.
Make your measurement process easy and start using the device hassle-free
