combination pH/ORP probes

I'm interested in the same thing (also Cu2+ ions).

What continent are you on?

North America in the U.S. of A. Colorado to be specific.

I would suggest that you contact Hach Company, who are based in Colorado actually, Loveland, just out of Denver.

McMaster Car.com carries reasonbly priced equipment for Ph determination.

KEEP IT CLEAN AFTER EAGH USE...W DI WATER >>>LASTS FOR YEARS

or paper ph strips FOR CHEAP AND DIRTY QUICKLY.......

Mr. Guy

Yes, they work well. Like anything else, take proper care of them and they'll do their job well for years.

Personally I like separate probes and transmitters. The reason: you can take one unit out of service for cleaning or calbrating without affecting the other. And, if the electronics (transmiiter) fails for one probe, you do not lose the other when they are separate devices. Lastly, with a dual probe, if one portion of the probe malfunctions, you have to replace the whole unit which is more costly that just replacing one defective probe, ph or orp.

actually, the combination probe that I found from Yokogawa is less than 1/2 the cost of one pH probe, and the ORP probe that we are using is even more expensive. So like I said, costwise it seems to be a no brainer. But the local supplier is not returning my calls for current users of the product, so the powers that be are reluctant to purchase. If they won't return calls of that nature, how are they going to be with service or support.
