Description
The upgrade to the MQ-500, - this MQ650 reads a wider spectrum of 400 - 750nm
Comes as standard with the extension wand to attach the sensor, and also an option of a protective case (with foam lining).
The MQ-650 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 provides excellent measurements under all light sources, including LEDs. 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 saltwater aquariums where corals are grown. Note: The handheld meter is not waterproof, only the sensor. The cable and the A320 telescopic lance are waterproof (this lance is different to that included with other models)
