pH meter

I also use the Pinpoint pH monitor. I bought the AC adaptor to use it with my normal electricity and things work great using a Pressurized CO2 tank. This allows me to be very precise!
 
ive read it lasts like 12 months under continous use,,and for the probe to be replaced when it can no longer be calibrated

If you take really good care of them, i mean clean them a lot you can get longer than 12 months. I have got 18 months of continuous use before. But you have to be careful that the readings dont get to out of wack. These days i dont risk it and i replace within one year.
