Which 02 Analyzer do you recommend?

[Jarrett]

My brother is looking at getting an analyzer and is looking for recommendations. What 02 analyzer do you recommend buying and where can he get the best pricing on it? Thanks in advance.

Yep, that's what I have... works great. Saves you $200.

How technical does one need to be to assemble it correctly? I do okay programming computers, but I haven't built one yet. Since it's as important as the air I breathe, I'd hate to think I might muck it up...

If you muck it up, it won't work at all (as opposed to being just slightly off)... you need to be able to solder and you'll need to cut some holes in the case for the LCD, power, calibration knob and where the O2 sensor plugs in - dremmel works well.

Are you using the flow restrictor with it, or just the flow through?

The hardest part of these kits is cutting the holes in the plastic case. Otherwise you only need fairly basic soldering skills. If you are reasonably handy it should be percieved as a fun challenge, not impossible. If you are completely unskilled mechanically you would probably be best to avoid it. If things like replacing a light switch, fixing a leaky toilet, or replacing the lock set on your front door do not bother you then get a kit or buy the parts yourself and have at it.

I really like this thread for getting the parts yourself and making an analyzer that is better than the kits you can otherwise come up with.

Have fun,

Be sure you have a fairly low wattage soldring iron. 15W is about right. 30W is waaay too hot.

Good to know, thanks! I may just give this one a shot.

I have used the Oxycheck, but prefer the Analox O2. I really thought about getting a kit from oxycheck,(great price-easyassembly) but wanted a smaller, no-hose, water resistant, more compact "travel friendly"analyzer.

Scuba Toys shipped one to me "on the bouble", don't recall the price now but it was not expensive (they give 10% off to SB members)
