1 Introduction

METTLERTOLEDOpuncture-typepHtheelectrodeswithXerolyt

polymer electrolyte are used for direct measurement at pH

infoods, for example fresh or curedmeat, cheeseand sh.

Beforeusingtheelectrode,readinstructionscarefully.

2 Important notes

goodcondition. For further information, ordering and service

(advice),pleaserefertoyoursupplier.

Safety
