1. PREFACE
1.1 Introduction
This instruction manual provides information
for the installation and use of the SC25V,
combined 12mm glass sensor; pH, Ref, LE
and Temperature. The SC25V is the best
choice for the majority of typical process-
and waste water applications. The sensor is
designed with titanium liquid earth, increased
electrolyte reservoir and large surface area PTFE
diaphragm combined with a long pathway inner
junction resulting in a longtime stability and
prolonged lifetime.
1.2 ATEX/IECEx compliance
The model SC25V is intended for use in
potentially explosive atmospheres. A number of
restrictions apply on the use of this sensor.
All varieties of SC25V are ATEX certified:
II1G Ex ia IIC T3...T6 Ga (see chapter 2.7).
EC-type Examination Certificate Number:
DEKRA 11ATEX0014 X
IECEx-type Examination Certificate Number:
IECEx DEK 11.0064x
Special conditions for safe use:
For ambient temperature see chapter 2.7.
Electrostatic charges on the enclosure and
cable shall be avoided.
1.3 Unpacking & Checking
Upon delivery, unpack the sensor carefully and
inspect it to ensure it was not damaged during
shipment. If damage is found, retain the original
packing materials (including outer box) and
immediately notify the carrier and the relevant
Yokogawa sales office. Make sure the Model
Code on the sensor is the same as on the
packing list. The Model Code and Serial Number
are found on the VP-connector of the sensor.
Check that option(s) that were ordered are also
included.

can deviate from the typical warranty period,
and the conditions of sales relating to the
original purchase order should be consulted.
Damage caused by wear and tear, inadequate
maintenance, corrosion, or by the effects of
chemical processes are excluded from this
warranty coverage. In the event of warranty
