Apogee Instruments quantum sensors measure photosynthetic light levels in both air and water, combining accuracy and durability at a competitive price. The sensor heads feature a unique blue diffuser that reduces spectral error to less than 5 % for sunlight (direct, diffuse, under plant canopy, reflected from plant canopy) and common electric plant lights (fluorescent, metal halide, high pressure sodium), and less than 10% for LEDs (blue, green, red, cool white, neutral white, and warm white).
The Meter has following special features :
- Next generation sensor head design
- Excellent cosine response
- Self-cleaning dome-shaped head
- Sensors are potted solid for extreme conditions
- Also available in multi-sensor “line quantum” models for spatially-averaged measurements
- Four year warranty
