Trouble-shooting

Sluggish response time (e.g. after a long and dry
storage period) is an indication that reactivation of the pH
sensitive glass may be necessary. Dip the pH sensitive
glass (but no further sensor parts!) into Reconditioning
(HF) Solution (METTLER TOLEDO product, article no. 51
319 001) for 5 min. Afterwards, rinse well with deionized
water and let sensor tip and diaphragm soak in reference
electrolyte for minimum 12 hours.
