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.
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.
1.4 Warranty & Service
Yokogawa products and parts are guaranteed
free from defects in workmanship and materials
under normal use and service for a period of
twelve months from the date of shipment from
the manufacturer. Individual sales organizations
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
claim, the defective goods should be sent
(freight paid) to the Service Department of
the relevant sales Organization for repair or
replacement (at Yokogawa's discretion).
