The MQ-210 quantum meter is designed for underwater PAR measurements and already applies the sensor's immersion effect correction factor to the meter readings through firmware.
The meter consists of a waterproof quantum sensor attached via waterproof cable to a handheld meter. The waterproof sensor incorporates a blue-enhanced silicon photodiode and custom optical filters with a rugged, anodized aluminum body with acrylic diffuser.
The underwater quantum sensor is typically used in salt water aquariums where corals are grown.
Note: The handheld meter is not waterproof, only the sensor and cable are waterproof.
Photosynthetically active radiation (PAR), or photosynthetic photon flux (PPF), is the spectral range (wave band) of solar radiation from 400 to 700 nanometers that photosynthetic organisms are able to use in the process of photosynthesis. Gardeners, greenhouse managers, growth chamber users and salt-water aquarists measure PAR to ensure optimal specimen health.
