I'm using a old sm101 Milwaukee pH meter that was given to me. (The green housing)I put a new SE220 probe on it and calibrated the unit. It holds true in the calibration fluids but fluctuates quite a bit when in the sump.
So I'm debating buying a whole new unit. I see Milwaukee has Upgraded there's in the last couple years. My question which is better for a sump ?
Milwaukee or Pinpoint.
