Instruction manual
1 Introduction
The METTLER TOLEDO InPro
is a low maintenance, autoclavable and pressure resistant pH
electrode with a pre- p ressurised liquid electrolyte and a reference
electrolyte together with a silver ions barrier. Please read through
these operating instructions carefully before commissioning, in
order to ensure trouble-free use. We recommend that you only
operate the electrode in conjunction with original parts from
METTLER T OLEDO. Operation and maintenance should be carried
out only by trained personnel and staff who have read and
understood the operating instructions.
2 Safety instructions
When cleaning or calibrating the electrode using solutions containing
acids or alkalis both protective spectacles and protective gloves
should be worn. Do not touch the electrode at the plug-in contacts,
since electrostatic discharges can damage the electronics.

In addition each electrode is provided with a serial number on the
red part of the plug-in head in order to enable identification.
This product complies with the ATEX guideline 94 / 9 / EC. The
complete declaration can be downloaded under www.mt.com/pro.
4 Installation and commissioning
1. While unpacking check the electrode for mechanical damage.
Please report any damage immediately to your METTLER TOLEDO
supplier.
2. Remove the protective cap and rinse the electrode for a short
time with deionised water. Carefully remove the silicon protection
from the diaphragm with the aid of the knife supplied (cf. green
instruction images on the packaging). If the electrode has
already been used the sensitive part can be cleaned if
necessary with a soft toothbrush and a mild soap solution, and
then rinsed for a short time with deionised water. After rinsing
the electrode should only be dabbed. Any rubbing of the
pH-sensitive glass can increase the response time as a result
of electrostatic charge accumulation.
3. Check the space behind the pH sensitive glass for air bubbles and
remove any air bubbles that may be present by shaking the
electrode lightly in a vertical direction.
