The Spectrum FieldScout PAR/Quantum Light Meter is a professional handheld device designed to measure photosynthetically active radiation (PAR) or quantum light intensity with precision. Perfect for greenhouse managers, horticulturists, indoor and vertical farmers, and plant researchers, this meter helps monitor light conditions to optimize photosynthesis, plant growth, and crop yield.
Equipped with a high-precision sensor and easy-to-read digital display, the FieldScout PAR/Quantum Light Meter provides fast, reliable measurements for field, greenhouse, or laboratory applications. It ensures data-driven decisions for lighting management and plant health monitoring.
Key Features:
Measures photosynthetically active radiation (PAR) in µmol·m⁻²·s⁻¹
High-accuracy quantum sensor for reliable readings
Real-time digital display for easy monitoring
Lightweight, portable, and field-ready design
Durable construction for outdoor and greenhouse use
- Provides accurate PAR light readings from ANY light source
