HELP! Milwaukee 3 in 1 meter

I went to use my Milwaukee 3 in 1 today and the ph just bounces all over the place. I've heard the probes go bad after awhile but its only 2 months old. When I tried to calibrate it I was only able to get it to read 3.0 in a 7.0 calibration solution. Is there anything I can do to fix it?

my hydro guy told me to stay away from Milwaukee :-(

pH probe electrodes need to be soaked in plain water for a while before use. The probe tips must also be stored damp. A piece of damp sponge in the meter cap will do it. If not done, meter readings will wander as described.

Yeah, I always rinse it after every use and keep a damp sponge in the tip when I store it. The meter was about 200 dollars so Im feeling a bit ripped off right now.The replacement probes are about 50 dollars.

Eek. If you're keeping your probe tip damp and it's still playing up, see about warranty replacement, if you can.

Are you by chance using an electronic ballast? I know my meter goes nutz if its near my ballasts, stops at about 8 feet away.

Check the ground connection on your lighting. Poorly grounded HPS lighting can put out a lot of radio frequency trash that can interfere with various devices. Electronic ballasts, due to their switching-style current limiting, have the potential to spew out much more than std inductive type ballasts.
