I purchased the Extech re300 about 2 weeks ago and have used it about 15 times so far. I need to measure ORP value, and I wanted something decent for the price. I seen there was another model on amazon that had more reviews, but I have used an extech before and I was fairly happy.

So far it has functioned great. I have read that orp meters less than 300 bucks can lose calibration and the sensors go out... so we will see how long it holds up, however I am very satisfied so far.

Things to note:

When I did a search for a ph meter this one came up, however when I recieved it I noticed I had misread the description. It is JUSt an orp meter. So I am thinking of getting the PH Extech coming up soon, but there are so many mixed reviews on all makes and models. Right now I am using ph strips and they are fairly accurate, but will be looking to get a digital reading of ph.

The reason for the 4 stars is that the meter works great but did not blow my mind. Maybe after 6 months of working I will come back and adjust my review.

As for storage, I have just wetted the end like the directions said. There is an automatic calibration and so far it seems to be accurate.

I have not used storage solutions or anything... and I have checked a couple times to make sure it is still "in tune"... so maybe it does deserve a 5 star rating.

What else can I say.
