THE SENEYE PAR METER

INCLUDING LIGHT METER
For $199.00 - including shipping - you can own a Seneye full-featured PAR Meter. The Seneye gives you incredibly accurate and detailed PAR readings, more than any other PAR meter on the market. The Seneye is the most accurate PAR meter for your aquarium, as it is the only PAR meter designed exclusively for aquarium use. Other PAR meters were designed for hydroponic (plant) usage, and adapted to be used in your aquarium. The Seneye was designed in Europe – hand crafted in a small facility outside London - from the ground up to be a PAR meter. This makes the Seneye PAR meter much more accurate for aquarium usage (see charts below) especially in the 400nm to 700nm range – the ACTINIC part of the visible light spectrum. This is the range where we need the most accurate readings for growing coral.. So for half the price of most PAR meters, you can get the best PAR meter – the SENEYE PAR METER!

AND THE SENEYE IS ALSO A FULL FEATURED LIGHT METER
THAT GIVES YOU:
THAT GIVES YOU:
LUX – the overall brightness of the light that shines down from your lights onto your fish and coral. This allows you to judge which light best fits your tank’s lighting needs, and in addition, will tell you over time – using the Seneye Graphing and Trending software – how bright your lights really are, and when it is time to replace them. With used in conjunction with PAR this gives you a very accurate indication of the true lighting condition of your aquarium.
KELVIN –the corresponding light “temperature“ of the light coming into your tank. A lower Kelvin number indicates a warmer - or more red spectrum – and this progresses upward until you get into the colder or bluer Kelvin rating. If the light above your tank is emitting light in the 5500k Kelvin rating – this is great for a planted tank – but not good at all for your coral. How would you know if you cannot check the Kelvin rating with a Seneye meter? Only the Seneye gives you this – with just a glance at the Seneye unit in your tank.

NO OTHER LIGHT METER GIVES YOU PAR AND LUX AND KELVIN ALL IN ONE SMALL DEVICE AND NO OTHER LIGHT METER ALLOW YOU TO TRACK AND MONITOR YOUR AQUARIUM LIGHTING TRENDS LIKE THE SENEYE!
LOOK AT THE CHARTS BELOW TO SEE WHAT THE SENEYE CAN TELL YOU WITH ITS EXCLUSIVE TRACK AND TREND SOFTWARE!
This is the PAR graph available exclusively with the Seneye PAR meter. This graph gives you a history of your PAR value on a daily, weekly, or monthly basis - going all the way back to the day you first put the Seneye PAR and Light Meter in your aquarium! And you can download a spreadsheet showing you your entire PAR history! No other PAR Meter can do this! |
This unique feature enables you to take a snapshot - a reading with a location in your tank and a time reference - so you can make comparisons with future readings in the same location. This will tell you how stable your current lighting is and ensure that your precious coral receive a consistent amount of PAR!
No other PAR Meter can do this! |
Here is the historic LUX values available only to Seneye owners. Like PAR and Kelvin values - you can see the historic readings of LUX on a daily, weekly, or monthly basis. Not only will this tell you if your fish and coral are receiving a consistent amount of light, but it will enable you to monitor the total light output of the lights over your tank, thus enabling you to replace lights as needed.

Another option available only with the Seneye - the Kelvin graph enables you to observe the Kelvin rating of your tank at any time your choose. Used with PAR, Kelvin gives you the most accurate assessment of the total light values coming into your aquarium available. PAR tells you how much lighting is being provided in the Actinic range - the spectrum of light that your coral need for maximum health and growth. Kelvin gives you the spectrum color range that enables you to judge the color temperature of your lighting. And this gives you the ability to tell if the lights you purchased are emitting the Kelvin rating as advertised. And like PAR and Lux, this graph gives the entire history of your Kelvin lighting from today all the way back to the day you installed your Seneye PAR and Light Meter!
No other PAR Meter can do this! |

PAR Photosynthetic active radiation is a measurement of light power between 400nm and 700nm. It is used to give an indication of the power of light present that is used by organisms which have photosynthetic cells such as plants and corals. The graph to the right shows the light used by various photosynthetic cells and the combined line of light used by all photosynthetic pigments. |
As you can see not much green light is used and absorbed, therefore it is transmitted or reflected by the plant which is why most plants look green. It also shows a slight flaw in using purely PAR as a measurement; for instance a lamp with high levels of green light would measure very high PAR but have little usable light for food where as a more reddish lamp may have a lower PAR but produce a higher growth rate in plants due to it being a more useable spectra. A green lamp would also make plants look very healthy (while potentially starving them) as they would reflect the green light but look healthy. It is for this reason that specialist plant tubes which are normally red heavy often deliberately put a large spike of green light in there lamps so plants don't look dull. This is why the seneye 3 point RGB graph provided can help to point out where the light is peaking. Again to help we have added a tab to allow the user overlay the combined PAR graph and see how your lighting fits.
We recommend that the seneye PAR function is used only as a measure against light readings taken from other seneye devices or a seneye PAR organism table. Why? most PAR devices are aimed for use in greenhouses where they are more interested in the red end of the PAR spectrum as this is where most terrestrial plant get there useful light from. The seneye device is more sensitive than most at light below 450nm (bluer). This is arguably the most important spectra for coral and why most marine aquarists use. |

Moreover, the Seneye device has no cosine corrector fitted; these are normally fitted to devices that are used to measure the sun so that they can be left in one position and the change in the suns angle depending on the time of year (its zenith angle) means that the reading is unaffected.
In an aquarium with a fixed light source this is not needed and adding a cosine filter may introduce light from placing you don't want. In our view a narrow angle light sensor will allow us to look at light sources with more accuracy and directional control.
