pH probe difference

[clk2609]

anyone know the difference between the standard pH probes versus labgrade or gold series? Is it worth the extra money to buy a better probe?

thanks

I can't answer that question but I can recommend the Pinpoint PH probe. Most probes suggest/require replacement after 6 months due to failure to recalibrate but the Pinpoint allows you to recalibrate it over 18 months (I got almost 2 years) and is also submersible for those all thumbs days. Not bad for a $50.00 probe IMO.

hi.
Use quality grade if you want to publish an article or you are doing research, otherwise, get the cheapy, and save a few bucks and spend time with your fish/coral instead.
