PAR Meter

[shookbrad]

I would like to buy a PAR meter but I have no idea where to begin. Does anyone have sny suggestions on which ones to buy?

Apogee is the way to go: Try here

Any that are cheaper? $300 is a lot.

If you have a decent multimeter lying around you can just buy the sensor it makes for a cheap PAR meter about $139.00. I went with the Apogee SQ-120. Just multiply the mV reading by 5 to get the PAR reading.

That sounds very interesting. So buying an Apogee SQ-120 will attatch to a standard Multimeter? Which function on the multimeter to I set it too?
Thanks!

You want to set it to mV. The Apogee sensor will put out up to 400mV so you want to be in that range. When you set it up you'll determine a correction factor (instructions are on Apogee's site and will undoubtedly come with the probe) and you'll simply multiply your mV reading by that number to get your PAR reading.

I'm planning on buy one with some friends to split the cost. I just want to make sure of one thing: The sensor is waterproof? When I submerge it in water there won't be any long term detrimental effects?
