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.
