The By-meter Apogee Mq-510 is the ultimate measuring instrument for seawater aquariums. Especially calibrated for underwater measurements, it allows to accurately mapping the light intensity (by) received by your corals. Thanks to its high loyalty waterproof sensor, adjust your ramps Led To maximize photosynthesis and avoid bleaching.
The light is the engine of coral growth. Too weak, your corals are expanding; Too strong, they undergo oxidative stress. TheApogee Mq-510 Eliminates approximations. Unlike standard models, the MQ-510 automatically applies a correction factor for the refractive index of water, giving you a real and immediate reading.
This unit consists of a portable (non-sealed) reading box and a high quality sensor connected by a 2 meter cable:
| Parameter | Value / detail |
|---|---|
| Measuring range | 0 to 4000 μmol M-2 S-1 |
| Spectral range | 389 to 692 nm ± 5 nm |
| Calibration uncertainty | ± 5% |
| Protection index | IP68 (immemerible sensor up to 30m) |
| Response time | Less than 1 ms |
| Materials | Anodized and acrylic aluminum |
⚠️ Important reminder: Although the sensor and cable are totally waterproof (IP68), the Portable player should not be immersed or exposed to water splashes.
💡 The Reef'Art Council: For optimal placement of your corals, perform measurements at different locations of the decor. A SPS coral usually will usually ask for 250-400, while a LPS will flourish between 75 and 150.
The MQ-510 ofApogee is specifically designed for underwater measurements. Its firmware already incorporates the correction factor of the immersion effect, which guarantees specific statements without manual calculation, which is essential to optimize the growth of corals.
Only the quantum sensor and its 2 meter cable are completely sealed (IP68 index) and can be immersed up to 30 meters. The portable control box (LCD player) is not waterproof and must stay dry.
This apparatus measures photosynthetically active radiation (by) on a range of 0 to 4000 μmol M-2 S-1, covering a spectral range of 389 to 692 nm. It offers excellent repeatability (less than 0.05%) and calibration uncertainty of only ± 5%.
Yes, the counter has a sampling mode (99 manual measurements) and an automatic recording mode that calculates an average every 30 minutes. It also provides an integrated daily total (DLI) mol M-2 J-1.
The data transfer requires the free apogeams software and the specific AC-100 communication cable. Note that a standard USB cable will not work with this unit.
