Qestion About My New Ph Pen

Discussion in 'First Time Marijuana Growers' started by Argaha, May 20, 2013.

  1. I picked up a Milwaukee pH600 pen today as well as some 7.0 reference solution.  When I opened the pen for the first time I noticed it was covered if what seem like crystals.  I'm not sure if I'm supposed to rinse these off as it may be some kinda packing material or not.  Anyone have experience with this issue?

  2. storage solution, no big deal, can just clean off.
  3. Ok thanks...I appreciate it!!
