What about this one ? I’m a cheap a$$! Lol


#4

There is one negative, the delivery time…it is coming from China, taking a month to get here.

Well, maybe two negatives…aside delivery time, be prepared, you really do get what you paid for. Replacement batteries are $4-$5, maybe more.

I get the feeling the companies sell the shells to anyone to put whatever inside. It gets to be a game on if and how long it will be good for.

Thanks @MacGyverStoner, glad you popped in and shared your 2 cents

Thank you @MacGyverStoner

Could be worth noting PH pens can require calibration. Might be worth getting some test solution. I picked up the one above for a buddy and it was way off, right out of the box. A minor adjustment with the included screwdriver and it works great.


#14

Thanks for the info, I searched last night and found a 3 bottle pack,it has the storage, 7,and I think it’s 4ph solution, on amazon it biopharm I think


#15

I just got my PH meter today… and it says I first need to calibrate it with distilled water at 25°C, and use these 3 packets. Then, I need to check calibration every few days or months. Not to mention storing it in special solution (additional item not included). Yikes! I was thinking I’d be getting something better/easier than the PH solution. I wish I had the solution instead. Can anyone weigh in on if it’s better to have a digital meter, a Test Indicator tube, or strips? Is it worth it? Is there a PH meter that is easier to use than this?


#16

It’s worth the hassle…


#17

Digital meter is worth the hassle and is far more accurate than other styles of test meters, as well as strips


#18

You can get a test solution that requires no mixing. I have a bottle of 7PH that I check mine again every so often.


#19

and you can usually store the meter in the pH 7 test solution, read the bottle for instructions.

I must be one of the lucky ones I got this Meter last year and its been doing me well , everytime I retest it its only off by one point.

I cut a piece of sponge and stick it in the cap and keep it wet all the time .
