DrDAq - pH in salt water

Postby Guest » Mon Apr 05, 2004 5:11 am

Hi, is the pH probe that comes with DrDaq only designed to measure in fresh water? When I try to take the pH of salty water, the reading fluctuates wildly, from 0 to 14. Seems to work Ok with normal water, though.

Are all the pH probes you sell like this? Will any other probe that works in salty water work with DrDaq.

Hi,

We only sell this one probe, it only works with DRDAQ, I would advise looking at:

www.farnell.com
www.rswww.com

They might have a wider selection. You will then need to make your own sensor, details on this can be found in the drdaq help manual.

Best regards,
