Dammit my Checker PH Pen must have went out. This morning is a calibration day for me and the pen wont calibrate to 7.01 it wont go below 7.22. It calibrates with 4.01 fine.. I called them and am waiting for a call back the thing is only 3 months old... This makes me very nervous. I am wondering if my PH is off... I dont have 50-100 bucks for a replacement..
