Product Specs

The PHH-7011, PHH-7200 and CDH-7021 are easy to use and feature replaceable sensors. The PHH-7200 can measure pH or conductivity and will automatically recognize which sensor is installed. Each kit comes in a convenient carrying case with buffer or standard solutions for easy calibration.

Rated 5 out of 5 by from Great Brewing Ph meter I bought this Ph meter for brewing and I love it. Super easy to calibrate, high accuracy, and stabilizes quickly. Highly recommended.

Rated 5 out of 5 by from Good quality and price. Purchased about 6 months ago and used 2-3 times per month since for home beer making. Meter calibrates easily and quickly everytime. Buffers and storage solution included makes this meter a great value. Can't say how long the electrode will last as I am still on the first one.

Rated 4 out of 5 by from Easy to Use! We bought this neat hand held pH meter to use inside production. We haven't used it inside production yet, but training how to use is easy and meter is quick to read. So far everyone is happy with our new pH tool!

Rated 5 out of 5 by from Excellent Product For experiments, I'd been dumb enough to try one of the dozens of cheap Amazon pH testers (which as it turns out are actually scam random-number generators whose product pages are loaded with fake reviews). I had used Omega for temp control items in the past and had never thought of Omega as providing pH measuring, but was happy to learn that they did. One of the things I like best about Omega is their phone tech support. I can call and get straightforward feedback from someone who knows his stuff and will direct me to the right product, which is exactly what happened in this case .The pH meter was easy to use and accurate, and helped greatly with testing.

Rated 5 out of 5 by from Works great! I looked at many PH test meters before settling on this one. I even ordered a really cheap one from another company and it didn't work at all. That was a waste of time. This meter works really well, comes with premixed solutions for calibrating, and solution for storing the meter. The probe is removable and has a really good cap for the storage solution. It come off easy and does not leak. I use the meter for hydroponics and wine making. It works well for both uses. It does not take a long time to read the PH. The carrying case it comes with is a nice feature, however, I would suggest that it be made differently. If you store the meter in the case in the position it is made to be in, the testing solutions are upside down. If one leaks, the solution will get over everything. The price was just right for this type of meter. I consider it a very good value.

Rated 5 out of 5 by from All the features I need Bought this a few weeks ago to aid in pH measurements for my first sour beer. Great features, easy to use, and will no doubt come in handy in other brewing and beverage applications.

Rated 5 out of 5 by from A cost effective, accurate, easy to use pH meter I collect rain water in a 1000L tote tank to use for my gardening needs & wanted a cost effective pH meter to test the pH while treating the water before use. A couple of weeks ago I purchased a PHH-7011 & I was impressed with the ease of calibration & use. It comes in a hard shell case with 2 small pH4 & ph7 buffers, a small bottle of soaking solution (for the meter's sensor tip). This meter has a quick response & doesn't take long to stabilize. I have also purchased bottles of pH4 & pH10 to calibrate the meter after the original ones are used up. My only complaint is the tiny bottle of 'soaking solution'. A tiny bit of this solution as lost each time the meter is taken out to be used so eventually it'll run out. pH probes need to be kept wet to extend their 'working life time' & I have been unable to see any listing for this solution at Omega. Its pH seems to read around 4 so I may just substitute the solution for buffer later. Aside from that I know that pH probes have a limited lifetime & it's nice to see that replacement probes are available for these meters.

Rated 5 out of 5 by from Easy to Setup and Use Bought the product to test pH levels in a small to medium sized spa. Glad to have the accuracy and reassurance this meter provides over test strips that can be hard to read. Also helpful that the pH reading is automatically adjusted based on temperature.

What is the proper way to store this device to preserve the electrode?
