Apogee Instruments MQ-650

Product detailed description

The MQ-650 ePAR metre is designed for measuring PAR underwater (400-750 nm) and, through firmware, already applies a correction factor for the effect of sensor submersion to the metre readings.

The metre provides excellent measurements with all light sources, including LED. The metre consists of a waterproof quantum sensor connected by a waterproof cable to a handheld metre.
The waterproof sensor contains a silicon photodiode with blue enhancement and its own optical filters with a robust anodised aluminium body and an acrylic diffuser.
The underwater quantum sensor is typically used in marine aquariums where corals are grown.

The handheld metre is not waterproof; only the sensor and cable are waterproof.
