Product Information

The MQ-510 quantum meter is designed for underwater PAR measurements and already applies the sensor's diving effect correction factor to the displayed results via the firmware. The meter consists of a waterproof quantum sensor connected to a handheld meter via a waterproof cable. The waterproof sensor consists of a blue-enhanced silicon photodiode and  optical filters with a rugged, anodized aluminum housing with an acrylic diffuser. The underwater quantum sensor is typically used in marine aquariums where corals are grown.


Note: The handheld meter is not waterproof, only the sensor and cable are waterproof. The device must be protected against splashing water! If the device is damaged due to improper handling, we reserve the right to charge the new price of the device.
