Apogee MQ-510 Full Spectrum PAR Meter (Underwater Sensor)

Professional PAR Measurement for Reef Aquariums

The Apogee MQ-510 is a laboratory-grade full spectrum quantum PAR meter specifically designed for LED reef aquarium lighting.
Equipped with an underwater cosine-corrected sensor, it delivers accurate PAR (PPFD) readings directly inside the aquarium—exactly where corals live.

Unlike older PAR meters, the MQ-510 is calibrated for full-spectrum LED lighting, making it one of the most trusted tools for reef keepers, coral farmers, and professionals.

Why the MQ-510 Matters

• Measures true PAR (μmol·m⁻²·s⁻¹) underwater

• Designed for modern LED reef lighting

• Eliminates guesswork when placing SPS, LPS, and soft corals

• Essential tool for coral growth, coloration, and long-term stability

• Widely used by coral farms, researchers, and advanced reef keepers

Key Features

• Full spectrum quantum sensor optimized for LEDs

• Submersible sensor for direct in-tank measurements

• Handheld digital display with instant readings

• Cosine-corrected sensor for accurate light angles

• Factory calibrated by Apogee Instruments

• No app, no Bluetooth, no distractions—pure precision

• 

Typical Reef PAR Guidelines

(General reference – every reef is different)

• Soft corals: 50–150 PAR

• LPS corals: 100–250 PAR

• SPS corals: 250–450+ PAR

Using a PAR meter allows controlled lighting, avoiding both coral starvation and light shock.

Francois Neo – AquariumPartner Insight

A PAR meter is not a gadget—it’s a decision-making tool.
The MQ-510 allows you to build a lighting strategy, not just “turn lights up or down”. If you care about coral placement, consistency, and long-term success, this is one of the most valuable tools you can own.
