Photon Flux Probe Delta Ohm DLP471PAR

Bring research-grade plant lighting measurements to your greenhouse, growth chamber, or field study with the Delta Ohm DLP471PAR photon flux probe. Designed to quantify Photosynthetically Active Radiation (PAR) in the 400–700 nm band, it delivers reliable readings in µmol·m⁻²·s⁻¹ to optimise photosynthesis-driven workflows. A cosine-corrected diffuser ensures accuracy under direct sun, diffuse skylight, or artificial grow lights, while factory calibration and on-board calibration data give you instant confidence in every reading. Compact, rugged, and ready to plug into compatible Delta Ohm instruments, the DLP471PAR is the smart choice for agronomy, horticulture, and environmental research—available with expert support from Stratosens.com.

Key Benefits and Applications

• Precision PAR for better crops — Measure the photon flux plants actually use, then fine-tune light intensity and photoperiod to improve yield, quality, and resource efficiency.
• True-to-reality readings in any light — Cosine correction delivers accurate results from low-angle sun to overhead LEDs, reducing placement sensitivity and saving setup time.
• Ready for field and lab — A compact, robust probe with a practical cable length makes it ideal for portable monitoring, spot checks, and research campaigns indoors or outdoors.
• Fast decisions, less downtime — Stable, repeatable measurements in SI units streamline daily tasks like lamp mapping, PPFD verification, and compliance documentation.
• Seamless pairing with Delta Ohm meters — Smart probe recognition and stored calibration constants enable quick, error-free setup with compatible photo-radiometers for a plug-and-measure experience.
• Versatile across sectors — Perfect for commercial greenhouses, vertical farms, seedling propagation, ecological field studies, and lighting validation in research facilities.
