Who can I bribe for a PAR meter?

some one in london needs to go buy one and do it ...sarnia has one. which is me..hammy has one which in biggie

How's that orphek led for PAR?

I have been bugging him about this as well as I have the same light as him. I think after vacation this winter I will just have to buy a par meter myself as I too asked about having someone come map my tank 
[/quote]problem is i have to be home to do that in the afternnon. where the ledsa re at there brightest

not really, you have the good par meter, you can hook it up to the computer and leave the sensor in all day and it will record data at set intervals and plot the results out on a chart.

[/quote]ohh i forgot i have the program yu buy from apogee. that is on a driver.  and download it on to yur puterr. and leave the smesor in tank ..will have to get a very long cord to reach the tank to the computer

You always plug your controller into the Atlantik and use quick set and there you can turn each channel on from 0 to 100% one channel at a time. That way you can test par with all channels at say 25% 50% 75% and 100%.

Hmm looking at the documentation for the standalone sensor it might be easy to plug one into an Arduino controller.

Thats cool! According to http://www.reefcentral.com/forums/showthread.php?t=2252932 you can also just connect the sensor to a volt meter as well.

I think I am going to order the SQ 120 and hook to a multimeter and go that route. I just called apogee and they said it would give me the same readings as if I were to buy the MQ 200 handheld full unit. Just multiply by five.

"How can I use a voltmeter to determine readings from my quantum sensor?

The SQ-100 and 300 series are considered to be self-powered and have been calibrated to 5.0 µmol m-2 s-1 per mV. Use a voltmeter with a mV setting to attain better resolution. Connect the positive lead of the voltmeter to the red wire of the SQ and the negative lead of the voltmeter to the black wire of the SQ. Once you are reading the mV output from the sensor, simply multiply this reading by 5.0. This will give you the µmol m-2 s-1 output from the sensor, otherwise known as Photosynthetic Photon Flux (PPF) or Photosynthetically Active Radiation (PAR)."

However, there is a huge discrepancy for LED lighting, the lady told me they calibrate to T5 lighting, and that EACH LED color will have a different variance....

How much are they? I may consider ordering one as well.

the whole par meter is 349    ..yu can get at the coral reef store in burlington

Still around 200 bucks... Hoskin marks up tje Apogee products.  I emailed them a while back asking what they sell the MQ-200 for and they quoted me $450 vs the $375 or whatever that other places charged.
