Instruments MW102 PH and Temperature Meter

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.

Great instrument, I use it for home wine making. Very easy to use, calibrated it once for 2 years of use. Had to buy another one because my first one got lost in a move. Lots of other choices out there but this ph tester is simply great. If I lose this one I will not hesitate to replace it with the same model again. I like it that much. Highly recommend it.

After trying several cheaper pH meters, I splurged for this and couldn't be happier. The ease of use and the accuracy are outstanding. My results are almost exactly the same as a friend's super fancy wine analyzer machine, and I only calibrated the meter once several months ago. I just keep the cover of the probe filled with storage solution and no issues.

We have a saying in my house, “You don’t always get what you paid for, but you never get what you didn’t pay for.” I initially looked at the portable $10 to $20 ones, but the one I purchased would not even calibrate. I resumed to my search and triangulating between reviews, prices, and my own experience landed on this one, as a likely candidate. I am only using it in my spa weekly, but so far it has held calibration and works reliably. I also bought the storage solution.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.
