Absolutely fantastic information--thank you so much!

Awesome video. Thank you so much!

I put my meter in 4 buffer solution .i got two meters and they was about 10 sigits off and i figured i need to put it in ph buffer 4 .i soaked the sponge and had it just above the sponge and now it dont read ph it says over range

I saw something about being able to go through the settings to check the PPM. Any videos from the same ph meter coming up Thanks.

Will the electrode tip last longer if it's not used as much? I'm about buying one, but I will only use it about 10 times in one year. Seems a bit expensive if it doesn't last long, especially since I don't really need it.

How long do i need to press those buttons to reset?

Can we use high concentration cl2 such as 500 ppm while dialuting

Hi my Extech ph meter keeps showing an error value during calibration it doesn't show 4 or 7 please help me out

Calibrating once daily and replacing the electro yearly making this pH pen very expensive.

what a waste of time
