Best PH Meter ???????

I bought the $15 one on ebay and it works great.

Expect to pay $120 + for a bona fide professional instrument. The kind with a replaceable tip.

I'm not really concerned with the price, I am just not sure what the best namebrand is to buy. I have no problems spending the $125.00-$150.00 on a meter, I just want to get the correct one the FIRST time. Anymore suggestions would be greatly appreciated.

if you want to get a good one and just buy it once in your lifetime and not have to worry about replacing it, spend $180 like i did, and get the hanna 98129. It is a pH, EC, PPM, and temperature all in one pen. It is highly accurate, and its very easy to calibrate. You can also replace the pH bulb as well. It has 1 and 2 point calibrations (but I always do the 2 point).
It looks like the 98130 is for high EC concentrations, much higher than the scale the growers use (it measures in part per thousands, we use parts per million!) So don't bother with that model. I personally really like my pen and it works great. The only thing that would be better would be some high-end chemistry lab equipment. Those could run several hundred to possibly thousands of dollars. So, as far as growing is concerned, the Hanna 98129 is about the cadillac of EC and pH testers.

Awesome, thanks so much racer, a definite answer was what I was looking for. I have been looking at the Hanna 98129 and the 98130 meters, I have found the 98129 for $115.00 with free shipping, brand new, not used, the company had 3 of them I think. Thank you again.

$115??????? Damn hydro stores charging an arm and a leg. Man, i wish i would've found a deal like that. That's a great price for it. You'll be happy with your purchase.

This is the best combo IMHO. And considering the price I dont think you can beat it for a continuous meter.

HANNA GroCheck Combo Meter HI 981404N

Great luck!!

I use the Oakton Ultrabasic. Really easy to use, accurate to within .1 pH and waterproof. It's all you need. $63 bucks here:

Oakton UltraBasic pHTestr Waterproof pH Meter - pH Testing - Chemistry - Physical Science - Carolina Biological Supply Company

You'll need to get a bottle of 7.0 calibration solution too.
