pH Meter for Fresh Water, will this work?

[reef_doug]

Will the Hanna DiST5 (Blue one) work for both Fresh & Saltwater?

Is it a good choice for under $70?

Thanks

I don't think that particular model has a pH probe but in general the Hanna probes are OK. Also if you are interested in salinity/conductivity also, I would check the specs to make sure it goes to seawater range 53mS or 53,000 microsiemens.

The DiST5 does not read pH. It only does conductivity, TDS, and temperature.

I didn't read it carefully enough.

How about the pHep5 (the red one +/- 0.01)?

The pH probe handheld Hannas are OK. Also see PinPoint pH probes.


The Hanna multi-handhelds have automatic temp correction as does PinPoint, I believe, for pH.

The Hanna handheld conductivity does not extend to the seawater range.

The pHep 5 is a fine choice of a handheld unit. Use two point calibration if you get it.

I prefer larger units that can be left in the water 24/7, however, so I can read it at a glance as I pass by.
