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.

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.

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.

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!

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.

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.

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.

Conductivity meter
Easy to use, text a bit small is the only con. Calibration is easy as well.

How often does this tester have to be calibrated? Looking to use in an industrial environment, and want to make sure constant calibration won't be an issue.
Asked by: water
Thank you for your inquiry! Calibration frequency can vary greatly based on the process conditions. Daily calibration would be a safe bet with a maximum period being around a month. Unfortunately, there is no set frequency and values should be observed carefully to ensure that changes are process and not meter related

Hello. I purchased a PHH-7011 almost 3.5 years ago that I mostly use for rain water quality for gardening use. It still works great but I'm wondering what the typical life cycle is for these pH probes before I need to buy another one. Thanks.
Asked by: Accidental Gardener
Thank you for your inquiry. The pH probe will have a shelf life of 6 to 12 months depending on the application and includes sitting on the shelf or not used.

Hello we have a PHH-7011 ph meter when I calibrate it it has a slope (pts) of 88%. However it doesn’t seem to hold the calibration for very long. It gives readings off by .30 within an also the temperature readings are off by 15 degrees. Any suggestions?
Asked by: Nate23
Thank you for your inquiry. If the probe is 6 to 12 months old, it will need to be replaced in general, unless, you can shock it back using a diluted white vinegar and have the probe soak for a 5 minutes, clean and rinse. Repeat the calibration to determine whether it had been rejunvenated and can measure accordingly, if not, then, will need to be replaced.

What is the required sample volume for the meter?
Asked by: Biomedical Engineer CW
Thank you for your inquiry on the pH meter. As a reference, you can use approximately 2 ~ 3 mL of the substance being measured, enough to cover the tip of the sensor.

How can the ORP be callibrated?
Asked by: TommyWA
Thank you for your inquiry about the conductivity meter. You will need to obtain a substance called Quinhydrone which is a reducer that generates a specific ORP value when mixed with 4 and 7 pH buffers. In a 4 buffer, saturate 1/8 gram in 50 mL of buffer and the Quinhydrone will yield a value of 265 millivolts, and a 7 buffer will yield 86 millivolts. (Unfortunately, Omega does not sell this substance.)

can't seem to find the probe part number on your site is it still available?
Asked by: sail
Thank you for your inquiry! The replacement pH electrode is still available and can be found by searching the part number PHE-7011.

What would you expect the ORP to read when placed in 1413 uS/cm conductivity solution? What would a recommended threshold for error be before the ORP requires a calibration?
Asked by: TommyWA
Thank you for your inquiry! Unfortunately, there is no tested value for ORP that is correlated to the conductivity solution. If the error appears to be exceeding the stated accuracy (+/-2 + 1 digit) the unit may need to be calibrated. Please feel free to the flow department (flow@omega.com) with any further questions.

Where do you get more of the soaking solution? The PHH-7200 came with a small vial of soaking solution for the sensor tip but I can't find anywhere on the website where to get a replacement. What exactly is in the soaking solution?
Asked by: Hazel
Thank you for your inquiry. The soaking soluiton part number is PH-SOL which comprise of a pint of 4M KCl solution and is available to purchase online.
