SPOTON QUANTUM PAR METER

SPOTON QUANTUM PAR METER – Scientifically Accurate Light Readings for All Grow Environments

The SpotOn® Quantum PAR Meter by Innoquest is a compact, affordable, and highly accurate tool for measuring Photosynthetic Active Radiation (PAR) across all light sources—including LED, HPS, MH, fluorescent, and natural sunlight. Designed for growers, researchers, and horticultural professionals, this meter offers three modes of operation and delivers real-time PAR and DLI data without the need for external software.

Key Features

• Accurate PAR readings from full sun to full shade, indoors or outdoors
• Compatible with all artificial light sources: LED, HPS, MH, fluorescent, halogen
• Three modes: Spot Measurement, Scan (area average), and DLI (Daily Light Integral)
• Displays DLI directly on LCD—no computer required
• Water and impact resistant (IP-65 rated)
• Integral mounting plate with options for stand, stake, lanyard, hanger hole, and magnet mounts
• ¼-20 threaded hole for tripod or camera stand mounting
• Includes sensor cover and soft carrying case
