I am a newer grower & purchased a Milwaukee SM100 PH meter shown below....my 1st PH meter.
Over the period of 2 grows the time it took to get a reading went from abour 5 seconds with minimal stirring of the probe, to 3-4 minutes with constant probe agitation to get the reading to stop slowly adjusting to the correct (?) level.
When I first really noticed it I questioned my hydro store guy about it after about 3 months of use & he said it was normal for the probe reading speed to slow from new but then stabilize after a bit. The meters instructions talked about the importance of keeping the probe wet with storage solution & I was religous about that.
By the time my 2nd grow was done the meter had gotten to the 3-4 minute timeframe to get a reading & I contacted the manufacturer about it. They 1st said that it sounded like I needed a new probe and mentioned their 6 month warranty period that had expired in my case, but were happy to explain that if I search Google I will find tons of retailers to sell me a new one. They then explained the importance of cleaning the probe at least monthly if not weekly with rubbing alcohol to prevent buildup on the probe sensor that causes the type of problem I'm experiencing.
I explained to them that nowhere in their manual supplied with the meter did it mention cleaning the probe regularly nor the consequences of not cleaning it......there is NO MENTION AT ALL OF CLEANING!!! I even included a link on their site to the manual included with the meter that is identical to what I rec'd with mine that has nothing about cleaning.....storage only.
They have not since returned my e-mails regarding their lack of care instructions supplied with the meter and my request to help me out somehow on a new probe.
My hydro store guy just says he can only warranty them for 6 months!!
At 1st I decided to buy a different brand of meter for $100 instead of replacing a $50 probe for theirs & giving them more business. But then I thought of a better & more fair way to do things....I bought a new probe today & when I get back from vacation & get growing again in about 2-3 months I'll just warranty the old one telling them it's the one I just got recently.....that way I get my orig probe replaced as they should have & then the 2nd one I paid for I can save as a spare!
The meter seems to perform well if all is cleaned & maintained well, but I would never again purchase another meter from them based on their lack of instructions & warranty support thereafter.
