Product Description

The Milwaukee Instruments pH600 is a compact pH tester with a narrow probe for use in small samples or test tubes, and has manual two-point calibration, a single-line LCD screen, a replaceable electrode, and a low power demand. A pH meter is commonly used to measure the pH of substance such as water, food, beer, or wine in laboratory, industrial, and food applications. The single-line LCD screen of this meter shows the current measurement. The meter has manual temperature compensation and manual one-point calibration through a trimmer on the top. Three 1.5V button batteries provide approximately 700 hours of use. The meter also comes with a calibration screwdriver and instructions.

A pH meter, also called a sensor or tester, is a device used to measure the acidity or alkalinity of a substance. A pH meter has either a portable or a benchtop body. Many portable meters are handheld devices. Some testers have an internal sensor, and may have a tip and body that fit inside of a container for measurement. A meter is commonly used in many different environments from laboratories to field research and manufacturing facilities. Researchers, manufacturers, and hobbyists use a pH meter in aquaculture, agricultural, wine-making, and water-testing, and for scientific applications. Some pH meters may measure additional parameters such as dissolved oxygen (DO), conductivity (also called electro-conductivity or EC), temperature, total dissolved solids (TDS), salinity, resistivity, or oxygen reduction potential (ORP)/mV.

Milwaukee Instruments manufactures electrochemical instrumentation and solutions for water analysis under the Milwaukee and Martini brands. The company, founded in 1998, is headquartered in Rocky Mount, NC.

I wanted an accurate, reliable meter to test my residential water supply. But I only needed to use it a couple of times a year so I didn't want to spend a fortune. I chose this one. I've it for about 2 years and it has worked as advertised.

I use this unit a few times a year. It gives me repeatable readings with no fuss or bother. I have to calibrate it each time before use, but that doesn't really bother me because I use it so infrequently. Just be aware that if you want accuracy you will also need a ph standard liquid for calibration purposes.

I have never owned a pH meter before, having been put off by the price and their reputation for being fragile and temperamental. At only $18, the Milwaukee PH600 seemed like a good way to test the water (so to speak). So far I haven't had a need to invest in anything more expensive. I have been using this meter to create hydroxide precipitates and found it to be very stable and reliable. I recalibrate it every day, but it is only ever off by 0.1 or 0.2. The calibration is single-point, but I find that if it shows 10.0 in a 10.0 reference solution, then it will read 6.9 or 7.0 in the 7.0 reference solution.

Just don't put the meter in very hot (e.g. boiling) water, the probe will crack like mine did. It still gives correct readings but I'm ordering another of the same model just in case I do something stupid again.

It's true, as per some of the other reviews, that calibrating this device by sticking the supplied screwdriver in a small hole in the back while watching the front is a bit inconvenient, but to be honest one gets the hang of it pretty quickly, and I can't really think of a better design. If the hole was in the front or on the side, then it would be more exposed to water drops, at least in my process which involves taking measurements while stirring. And the simple, manual, analogue interface of turning a potentiometer is hard to improve upon.

The meter arrived dry, but I put some pH 7.0 reference solution in the cap as soon as I opened the package, and as I said it works fine now.

Update:

I dropped my second one in salt water and it died. Even after removing the batteries, washing it in distilled water, and drying it, it still wouldn't go back to work for me. So I bought an $80 waterproof Hanna meter (HI98127).

I wish I had done more research before ordering this tester. After having problems with mine I looked online and have seen a number of other people have the same issues. Sure some people have pens that work but there seems to be a high number of people who receive faulty inaccurate devices. You may get one that works but you're taking a risk, and I know some people don't have the time and/or money to be gambling on products. Also you have to keep the tip submerged in liquid at all times, which isn't a huge issue but does make storing it along with other items a bit of a hassle since it has to be in a cup or some sort of open container with liquids at all times. Within 1 day mine was giving me all sorts of weird readings. I had already ordered a ph up/down kit with a testing solution so i waited about 3 days for that to get here(the whole time the ph pen just sat in tap water to keep it moist, didn't even use it after the first day) then I tested some water with the ph tester and tested it with my ph pen. Even if I adjust the screw in the back(this is for calibrating it) I can never get my meter to read below 12(even when the ph test solution I have indicates the water ph is 7 or below) and it even goes as high as 16 or 17 at times even though its supposed to be a tester for between 0-14. I'm going to try it once more tomorrow but so far it looks like its out of calibration and so far out infact that i can't even calibrate it to be close to what it should be. If you do get one of these pens atleast get the calibration solution so you can know immediately if yours is working or not.

I bought one of these Milwaukee pH600 meters to save time testing the water in my three freshwater aquariums. This little meter is so easy to use - and very easy to calibrate (only one calibration fluid is needed - 7.0). I now use Reverse Osmosis water (purchased water - not a home unit) and needed to simplify the testing (3 full five gallon buckets for my 75 gallon - 1 to 2 buckets when I do the smaller aquariums). Testing with my trusted liquid test kits takes so much time. While I didn't buy through Amazon, I came here to read the reviews when my meter failed (and probably wouldn't have purchased it if I read these reviews first - hence the reason I am writing one encouraging buyers to give it a chance). Yes, mine did lose calibration - but I found the company that makes it very helpful in trouble shooting the problem. After one week of spot on readings, my meter was reading too high (as I tested white distilled vinegar as per the company's recommendation and the reading was one whole point too high).

Rather than return the meter, I decided to give it a fair shot. I am glad I did. The company from which I purchased it sent me another packet of 7.0 calibration fluid -- and I have since I bought two more packets of calibration fluid just in case I need it. I now test one aquarium with the long trusted liquid test kit - then with the meter to insure the readings I get are accurate. My meter has been spot on accurate now for three weeks (since last calibrated - I have had it for two months). Using this meter also saves a lot of time when acclimating new fish. I acclimate pH as well as temperature. I check the water the fish comes home in and gradually match it mine (if it is different).

Here are some tips from the company that makes this meter:
