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.

The cap over the end of the probe is very tight, but does slide off with focused effort. I keep a quarter inch, or so, of storage solution in the cap and always store it with cap on, tip immersed. I simply cut a hole in the box lid so the probe will be stored vertically as the solution will otherwise capillary out and evaporate leaving some KOH crusties on the side. This happens anyway, but slower, and the point is to keep the probe stored in a wet state. My father’s advice on tools was to spend the money on quality and then be sure to take care of them. If you do, they will last, be cheaper in the long run, and you get the satisfaction of handling a quality tool. For my fairly humble current, and anticipated needs, this one hits the sweet spot.
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.
We've now retested many of our recent wines with this meter and have had to readjust the SO2 levels to prevent spoilage. Unfortunately, the SO2 levels of many of our older wines was insufficient (given the actual pH levels) and had to be tossed.
