Product Description

Waterproof pocket testers are designed for all applications. The IP67 Waterproof casing and double junction replaceable electrode make them suitable also for heavy duty applications, such as Waste Water treatment and Agriculture. The modular design allows easy electrode and battery replacement. They have a stability indicator and hold function that freezes the display for easy and accurate recording. The large display also has graphic symbols to guide you through all operations. Complete with a temperature probe for faster and more precise temperature measurement they compensate automatically for temperature. Calibration is made automatically in 1 or 2 points with memorized standard and NIST buffer sets. Auto power OFF saves battery power after non-use. The double-junction electrode can be replaced in a very fast and simple way. pH55 is supplied complete with protective cap, 20ml, pH 4.01 and pH 7.01 sachets of calibration solution, hard carrying case, batteries and instructions. Range: -2.0 to 16.0 pH / -5.0 to 60.0 degree C. Resolution: 0.1 pH / 0.1 degree C. Accuracy at 25 degree C: +/-0.1 pH / +/-0.5 degree C. Typical EMC Deviation: +/-0.1 pH / +/-0.3 degree C. Environment: -5 to 50 degree C ; max RH 100 percent. Battery Type: 4 x 1.5V; IEC LR44, A76. Battery Life: approximately 300 hours of use. Measures 38mm diameter by 200mm height.

I've used many pH meters over the last couple of decades for a variety of purposes which included brewing, gardening/hydroponics, and aquarium keeping. Over that time, I've used some meters which were exceptional and many more which were really quite poor. The Milwaukee pH56 is actually one of the better ones I've used, especially at the price.

This is the only pH meter I've personally owned (versus the very expensive meters I've used at work) that has proven to be consistent, reliable, and does not need to be constantly recalibrated.

I've had to calibrate this meter exactly once so far, and even that was just to satisfy myself that it had been done as it read the 7.0 and 4.0 reference solutions correctly "out of the box". The process was extremely easy, which is nice. Never again will I use a "manual calibration" meter. I still double-check the calibration by testing the reference solutions each time I need to use the meter, but so far I have not had to re-calibrate. So nice :)

After having used a number of cheaper and lower-quality meters, some of which I've purchased here on Amazon, I would not hesitate to recommend this Milwaukee PH56 to others. It's been great for me so far.

I *strongly* recommend purchasing the pH 4.0 and pH 7.0 reference solutions and pH storage solution with the meter if you do not already own them. Although the user's manual states that the pH meter can be stored in water, I much prefer to use the correct storage solution.

Accurate for reading pH and ORP but if you want to read negative ORP for water ionization, you must buy or get some very strong acid stronger than vinegar. Once placed in the strong acid for one day, it will read negative ORP. The customer service is excellent, easy to contact and will help you with all your questions.

If you are biting your fingernails at this one, drop the cash and do it. pHing your mash/sparge is key, whether you are a fly or batch sparger. .01 pH resolution is a must, in my opinion. My only beef is that it doesn't come with storage solution or a storage solution container, so you'll have it sitting in a glass of bought solution forever instead of a nice custom container.

It works great, simple to use. Too a few tries to calibrate it, only because I had never used one before, it's very easy now that I know how.

Product is as expected - works well - a little hard to read the display inlow light but otherwise is a superb product.

I bought 2 of these to measure wort pH. One for myself, and one for my daughter who works in a lab and knows her way around lab processes and equipment. Neither one of us have been able to calibrate our devices. After calibration I measured the pH of buffer solutions and the measurements weren't close to what they were supposed to be.

I use this for brewing beer. I prefer the accuracy to the pH 55 model. The price is the best I've seen. After about 5 uses, I have had no trouble with calibrating the device or with the electrode going bad. I suspect users are having trouble with this device because of 1.) improper calibration or 2.) improper storage/cleaning. Here's what I do to get good results:

1.) calibration- You have to calibrate between uses. It doesn't keep it's cal.

At first I had trouble calibrating with the 4.01 step. This was happening because the 4.01 solution was getting diluted with the 7.01 solution that was already on the probe from the last calibration step. To avoid this, spray the electrode with distilled water and wick it dry with a paper towel (don't actually touch the electrode). Then put it in the 4.01 solution and the calibration should only take a few seconds. Perhaps other users don't need to do this, and I'm guessing that's because they use have so much solution that the dilution doesn't confuse the calibration as much. This will still lead to an inaccurate cal. I'm surprised that the guy in the pH55 Cal movie on youtube has success with his cal even though he doesn't follow this procedure... Maybe it's because the cal routine isn't looking for the accuracy that the pH56 is spec'd to...

Also note that sometimes little air bubbles might get under the cavity that houses the temp probe and electrode (not in the electrode itself, which can also happen). I've noticed that this leads to inaccurate readings. To avoid this, I swirl the cup to get the air bubbles out.

2.) storage/cleaning- I store it in a shot glass filled 1"high with MA9015 storage solution I got from Northern Brewer ($9) between uses.

Everything works great. Only challenge is to keep electrode wet. Maybe they could design a clear and slightly larger cap to work in this way.
