Review: good piece of equipment works well reads slow at times but so far accurately to a pretty good degree - this meter works well we called the company and spoke to the male (sales guy/tech) good help and want over meter and calibrated it three times (meter got more closer to the 4.01 (around 4.02, 4.03 (it does it times tak a while to find itself and can wounder around +/- 5 (there is a window of 3.96 to 4.06 which is 4 ). we tried several meters the Oakton EcoTestr pH 2 is a good meter but it only reads 0.0 good back up and it really works wells out of the others. for the Milwaukee MW102 PH and Temperature Meter we find it works just a little better and gives more reading. Calibration works best if you use wash sample 4.01 than to sample 4.01 with temp prop and repeat. this meter is not junk it does take a little time to read to higher level the Oakton EcoTestr pH 2 is faster but not has accurate but close. the Milwaukee MW102 PH unit is a basic PH meter with temp sample field unit good price in market for what it is--(no data sd card slots etc...). thanks milwaukee. (if the unit goes bad or anything i will post it so far so good). unit is runing ok so far had to re calibrate (did it several) times with wash 4.01 and the test 4.01 etc.. and the meter sames to be reading +/- about 2 or 3 more close to 2. the meter works well just wish it would find its calibration zone faster. there are times where is just struggles to find the calibration and the Oakton EcoTestr pH 2 is all ready there. I have ordered cleaning solution to see if this helps. ok i am returning this unit the 102 and will try the Milwaukee 105 pro model. the 102 just too many time takes to long to find it self to many times, eats up way to much time and i have to 2nd check it (so if i check 50 pools a day this meter will kill me... maybe probe change or broad but i can not use it working like this. i will update on the Milwaukee 105 pro after using it i will update findings. OK Milwaukee 105 pro works great. We had to call the company and get a replacement probe for unknown reason the 1st probe was faulty. the tech guys at Milwaukee are very helpful and help us with new replacement probe. the Milwaukee 105 reads a little faster it sames than the 102 but the run is at time very close. BUT it works very well and both PH and TEMP are displayed on screen with this unit makes it nice to not have to switch screens. (the Oakton EcoTestr pH 2 is faster). this test is great for bench and table work. (after calibration this 105 meter was 100% on the money 4.00 and 7.00 and reads with a very high degree accuracy. Final NOTE: Both units 102 and 105 Milwaukee's are (2 points) calibration the Oakton EcoTestr pH 2 is a (3 point) we called many companies for the answer and we are told that 3 points calibrate faster and many companies are moving to the pens and 3 point and auto cal from factory like the Oakton EcoTestr pH 2 this pen has factory calibration without any butter set by the factory watch you can at any time set it back to factory ((we checked factory and it is right on for 4.0 ((not 0.00)) that good. like to see other meters have this option. conclusion: 102 and 105 Milwaukee's are (2 points)slower than (3 points) work great. Great product and the Milwaukee's customer service was very helpful and fixed any issues. the Oakton EcoTestr pH 2 we use and it is a great meter with great factory reset calibration without solution. hope this helps all and please leave commands for others if you want thank you.
Review: Amazingly accurate, the best meter I have used so far. - I use a PH meter for Hydroponics. I have been through several PH Meters from several manufacturers over the past 2.5 years. I had the HM PH200 Digital pen & had to keep replacing the probe, a few cheap yellow Milwaukee pens that just die & a few other $50 meters. Needless to say, I have been pretty disappointed. Between faulty probes & units unable to hold calibration, I never can get accuracy. I finally had enough & after researching meters a bit, I settled on this one due to price & the reviews. So far I am very happy with this unit. I have more faith in the calibration & readings of this unit. During calibration, this meter requires you to calibrate to 7.01 & then do a slope calibration to 4.01. I have not seen this with other meters, but once calibrated the unit is very accurate & holds calibration without issues. I may have made it sound complicated, but it is pretty easy to calibrate. After about a week, I usually recalibrate, but when I go to recalibrate, I find it is only off by 0.02 at most, which is within acceptable limits. Nonetheless, I recalibrate it anyway since I have the solution out anyway. I also like that this meter uses temperature to adjust PH readings accordingly, increasing accuracy. Not all meters, especially the cheaper ones, adjust the reading for the temperature. My last pen had a little sponge in the cap that would dry out rather quickly, so even in storage I would have to check it often & reapply storage solution to prevent it from drying out. But this meter has a little bottle that slips over the probe which holds a generous amount of storage solution when the meter not in use. I feel I could leave this unit with the bottle of solution on the probe in storage much longer without checking it & not have the probe dry out. I like that it has a little hourglass indicator that tells you if it is done taking a reading. Readings sometimes take a while, especially in moving liquid. However, in standing liquid with no movement you will get a reading pretty quickly. What I do is leave the probes in the sample I am testing for a little while (5-10 mins) & then take my reading, I find I get a more consistent & accurate reading when I do this. The wires on the probes are long, which is nice, but the unit is a little large & holding the unit along with 2 probes to get a reading is a little more cumbersome than with the pen meters available. Since the cables are a decent length, you can set the unit down & hold only the probes, making it easier to handle. I was concerned the cables would short out at the plug after repeated use because they are not that thick, so I applied a little electrical tape where the wire meets the plug to alleviate stress on the cable. But even if they do fail from constant use over time, replacement probes are pretty cheap compared to some meters out there. For me, I am only interested in getting accurate measurements because PH is very important in hydroponics. So even though this meter isn't the most convenient thing to use, I am more confident in the readings I get when using this meter & it's accuracy shows in my garden. I highly recommend this unit.

## Questions & Answers

**Q: Do you have the complete list of what comes with this unit ?**
A: Yes1 x MW102 Unit1 x 9v Battery1 x Temperature Probe (MA830r)1 x PH Probe (MA911B/1)1 x PH Probe cover (a small bottle that fits on the PH Probe when not in use that holds storage solution)1 x User Manual & Registration Card1 x 20 ml sachet of PH 4.01 Calibration Solution1 x 20 ml sachet of PH 7.01 Calibration Solution1 x 20 ml sachet of PH Storage Solution Packet

**Q: What is the pH range measured with calibrated using pH 7.01 & pH 4.01 buffers? pH 7.01 & 10.1 buffers?**
A: the calibrated range of the ph.7 and ph4.0 buffers is .5 degrees accrurate...I have used this equipment for years and find it to be great...have not used the 10.1 buffer solution in food processes...but will tell you this equipment is very reliable...

**Q: I've seen tap water used as a rinse solution.  When is it necessary to purchase Milwaukee rinse solution?**
A: I have also seen tap water used for rinsing. In fact the calibration video on the Milwaukee site show the man using tap water for rinse.

**Q: Does this product come with a warranty?  It seems nearly impossible to find a reliable, yet  affordable PH meter.  Might this be the one?**
A: I don't recall about the warranty. I can however speak to the ease of use, reliability, and the fact that i am very happy with the meter. I have had it for over a year now. The temperature prob is great and the pH meter is easy to calibrate.

### ⭐⭐⭐⭐⭐ Works great for Cheesemaking, fast, easyand great price!
*by S***S on July 26, 2025*

I have a small artisan creamery and use this for cheesemaking. It is easy to use and calibrate unlike 2 other brands I have used and as accurate. I have had one for almost 2 years and it works pretty well at a much better price. I had just as many problems with my $600. PH meter (they are all finicky)! I replace the probe as needed. After 2 years I bought a new entire unit to have a back up.
