Handheld Digital PH and TDS Meters

[Kurt Copeland]

These sell on eBay for ~$16 to $20 per pair.

Does anyone have any experience with these? Are they accurate? Do they last? Are they worth it?

Hey Kurt are these for saltwater?

 

[Kurt Copeland]

These are intended for dirt, however, they will work if the tips are immersed in an aquarium.

 

[twilliard]

My only question would be if it goes down low enough for saltwater and also calibration.
Would it be worth it?? Sure if you are like me and grow the worlds hottest peppers!!

 

[Kurt Copeland]

I LOVE hot peppers!

I may have to start a garden, too.

I suppose the question I SHOULD be asking is...

What is the most reliable and relatively inexpensive continuous ph meter for AQUARIUMS?

Any combination of ph, salinity, temperature and/or other parameters in a continuous metering system would be appreciated.

In retrospect, I said these were really for grow farms and hydroponics but I just found the same product on drsfostersmith.com for fish.

I have both. The ph is decent but be sure to keep calibration fluid on hand as you have to adjust it every couple weeks. Tds meter works just fine.
