Product Description
Apogee offers two different underwater calibrated meters at two different price points. The basic MQ-210 features our original detector that is excellent for broadband light sources. The research-grade MQ-510 features an improved detector excellent for all light sources, including LEDs, and matches LI-COR and Kipp & Zonen PAR sensors in accuracy while costing much less.
Rugged Submersible DesignEngineered for reliability in challenging aquatic environments, the MQ-210 features a UV-stabilized, corrosion-resistant housing and a robust polycarbonate and stainless steel body. This ensures both long-term performance and submersibility up to 30 meters, making it well-suited for demanding underwater research and monitoring tasks.
Precision Quantum SensingThe MQ-210 employs a quantum sensor with a cosine-corrected silicon photodiode, ensuring highly accurate PAR measurements in the 400-700 nm spectral range. NIST-traceable calibration offers scientific confidence and comparability, while the optical glass dome window safeguards sensor integrity during extended aquatic deployments.
Versatile Data IntegrationWith analog output (0-2.5 V) and compatibility with most standard data loggers, the MQ-210 seamlessly integrates into existing data collection systems. Its low power consumption and customizable 5-meter polyurethane cable facilitate versatile field setups for scientists, researchers, and environmental professionals.
FAQ's of UNDERWATER QUANTUM (PAR) METERS (MQ-210):
