pH/ Thermometor Testers

[reefeel]

Does anyone have a electronic pH tester? I have been looking at Hanna's pHep 4. Does anyone know if this is a good product?

Hanna's are only accurate to 0.1+/-
So an 8.1 could "read" 8.0or 8.2 Big difference...
For $20 more...
Pinpoint's are good to 0.02+/-
So the same 8.1 would read 8.98 or 8.12...
And the replacement probes cost the same..

The Pinpoint is a very nice tool. I've also tried the Milwaukee brand and found the Pinpoint monitor to be much more accurate.

I have Pinpoint as well , including the thermometer which moniters 4 tanks. Both are great and highly recommended.
