The Hansatech QSpar is a large-area, cosine-corrected quantum sensor designed for precise measurement of photosynthetically active radiation (PAR) in the 400–700 nm wavelength range. Featuring a matched photocell and handheld display, it offers exceptional linearity (≤1% deviation to 3000 W/m²) and multiple ranges—0–20, 0–200, and 0–2000 µmol·m⁻²·s⁻¹. With a 0–2 V analog output and compact design, it is ideal for calibrating light levels in electrode chambers like DW3, LD1/2, and LD2/3.
