Milwaukee Instruments PH55 pH Waterproof Dual Level Temperature Meter, Pocket-Size, -2.0 DegreeC to 16.0 DegreeC Temperature Range, 0.1pH Resolution, 38 mm Diameter

Works great, I get consistent readings every time. I use 5-5gal buckets and I always have to lower the ph. I lower the ph and then I check the ph in every bucket. They are rarely the same ph after I add ph down the first time. I usually have to lower the ph again. However, it doesn’t matter how many times I check the ph in each bucket, I get the same reading. For example, if I check the ph in bucket 1, and the reading is 6.4, and then check the other buckets. If I go back and test bucket 1 again, I’ll get 6.4 again. The other buckets will have a slightly different ph, but if I check them multiple times, I get the same reading as the previous check.It is kind of slow at reading the ph. I hold it until the numbers quit moving, takes approximately 20-30 seconds.I baby my meters, and keep storage solution in the cap when I’m not using the meter.For the price, it’s hard to beat this meter. I’d definitely purchase it again. I’ve been using it for a month or 2 on a daily basis.

You need to buy a bottle of storage solution to begin operating this device. I did not see where that is listed, so now I am ordering that and waiting for it to be delivered.When I removed the protective cap a clear liquid came out and some small bits of either glass or hard plastic so I'm not sure if it's broken or what.I have no way of knowing if this works cause I need to receive this solution

I’ve been struggling to get consistent ph readings for my pool, test strips are too vague, I bought a lamotte test kit and that’s all over the place, this thing has always been on point. Make sure you get the calibration fluids and the storage solution.

Easy to calibrate reads well and stays consistent 👌 so far its the best one I had ,and cheaper then the know name brands, just keep it in drinking water or solution 😉

No he podido calibrarlo, ya que al momento de la calibración lo sumerjo a la primera solución pH 7 y este no la guarda, en la pantalla del dispositivo aparece "SET" luego "REC" y luego nunca aparece el "OK" fue una grande inversión perdida alguien puede ayudarme?
