PG200N UVA Sensor Head
UVA sensor Head Introduction
The UVA Sensor Head is an optional add-on for the PG200N Spectral PAR Meter, designed for professionals in indoor farming, horticulture, and agricultural research. This accessory enables users to accurately measure the UVA spectrum (320–400 nm), expanding the PG200N’s capabilities to support advanced light spectrum analysis for plant growth optimization. With growing evidence of UVA’s role in plant development, this upgrade brings new precision and insight to spectral monitoring in controlled agricultural environments.

Unlock UVA Insights in Precision Agriculture
As modern horticulture shifts toward precision lighting and spectrum control, growers and researchers are turning their attention to a less-explored but increasingly vital wavelength — UVA light (320–400 nm). Backed by recent studies, controlled exposure to UVA radiation has been shown to trigger the production of flavonoids and phenolic acids—compounds that enhance fruit color, texture, and resilience. In addition to improving overall plant vigor and nutritional value, UVA light supports natural disease resistance by activating plant defense mechanisms and reducing the need for chemical pesticides. Optimized UVA lighting can also help extend post-harvest shelf life by slowing fruit deterioration, offering practical benefits for both growers and consumers.
To meet this emerging need, UPRtek introduces the UVA Sensor Head Accessory for the PG200N handheld spectrometer — a compact yet powerful UV sensor designed for indoor farming, greenhouse environments, and controlled agriculture settings.
UVA spectrum is beneficial for indoor plants
Why UVA — and Why 320–500 nm?
While standard UVA is defined within the 320–400 nm range, the new UV sensor head goes further, covering 320–500 nm to include the blue light spectrum (400–500 nm). This additional coverage is no coincidence — blue light plays a major role in photosynthesis, phototropism, and photomorphogenesis.
By combining UVA and blue light measurement into a single sensor, the PG200N platform now enables:
- A more comprehensive view of plant-active radiation
- Side-by-side spectral analysis of UVA vs. blue light
- Greater flexibility for future UV and blue light tuning strategies in agriculture
Whether you’re developing a custom light recipe for leafy greens or validating the UV spectrum performance of a greenhouse fixture, this sensor delivers actionable, high-accuracy spectral data for decision-making.
