Your cart is empty.The MQ-510 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 salt water aquariums where corals are grown. Note: The handheld meter is not waterproof, only the sensor and cable are waterproof.

Not a good purchase experience at Amazon. A old model was sent to me as new model should have blue sensor. Scratch everywhere which to me means this is not a new old. Seems used one. Box unsealed before send as you can see there’s two round label (image should blue sensor).On box.

Everyone that knows anything about lights and plants knows that PAR is the way to measure how much light a plant is really getting. This device measure just that, accurately and very simply. Unfortunately, i believe that this product is slightly expensive for what it really is--it seems you mostly end up paying just for the quantum sensor itself and very little resources were put into designing an update handheld device. I ended up buying a used mq500 version of this device from a friend for a much better price. For this, I give it 4/5 instead of 5 stars.

Works much better than the original Apogee PAR meter. The original meter was reading 135 above what this PAR meter read. After adjusting my lights with the new meter, my corals are back to growing again.

would be nice if they had spent some of the very high price for a manual
