YOKOGAWA K1500BZ User Manual

1. PREFACE
1.1 Introduction
This instruction manual provides information for the instal-
lation and use of the Yokogawa combined pH electrodes
SC21 and redox electrodes SC29 series.
1.2 Unpacking and 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 and then
immediately notify the carrier and the relevant Yokogawa
sales office.
Make sure the Model Code and Serial Number on the
sensor are the same as on the packing list. Also, check any
option(s) that were ordered are included and correct.
1.3 Warranty and Service
Yokogawa products and parts are guaranteed free from
defects in workmanship and material under normal use
and service for a period of (typically) 12 months from
the date of shipment from the manufacturer. Individual
sales organizations can deviate from the typical warranty
period, and the conditions of sale relating to the original
purchase order should be consulted.
Damage caused by wear and tear, inadequate mainte-
nance, 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).
The following information must be included in the letter
accompanying the returned goods:
• Model Code and Serial Number.
• Original Purchase Order and Date.
• Length of time in service and description of the process.
• Description of the fault and circumstances of the failure.
• Process/environmental conditions that may be related to
the failure of the sensor
• Statement as to whether warranty or non-warranty
service is requested.
• Complete shipping and billing instructions for return of
material, plus the name and phone number of a contact
person that can be reached for further information.
• Clean Statement
Returned goods that have been in contact with process
fluids must be decontaminated and disinfected prior to
shipment. Goods should carry a certificate to this effect,
for the health and safety of our employees. Material Safety
Data sheets must be included for all components of the
process to which the sensor(options) have been exposed.

2. General specifications
The specifications for the sensor are clearly shown on the type
plate attached to the electrode cap. For detailed specification
follow GS 12B06J01-E-E / GS 12B06J02-01EN-P.
3. Installation
3.1. Preparation for use
After removing the protective cover cap and the dust cap of
the connector, the electrode is ready for use.
3.2. Mounting
The electrode must be fitted with an electrode cable WU20.-LT.
For cable color coding refer to IM 12B6W1-01E-H. Depending
on choosen host refer to respective IM.
The method of inserting an electrode in a fitting is shown in
fig. 2 and 3. The dimensions of nut is shown in fig 1. The nut
can be ordered separately under part number K1500DW.

3.3. Functional check and calibration
A check for correct functioning of a electrode can easily be
made using a buffer solution of 6.87 and/or 4.01 pH. For
1
redox with quinhydrone, when 1-20 grams (± 1 teaspoon)
2
quinhydrone is added to each buffer, it will produce a stable
3 Redox potential of 96 mV and 265 mV respectively. Mostly
only 1-point calibrations are performed. Some analysers also
4
have the possibility to adjust the slope (2-point calibration.)
5
3.4. Cleaning
6
The electrode should be cleaned with care using a soft cloth
7
or tissue soaked in soap suds, alcohol, aceton or white
8
spirit. If the deposit is persistant it may be removed using
9
a domestic washing liquid diluted with water. This method
A
can affect the sensitive metal layer of the electrode and
B
consequently, precaution is required.
C
3.5. Storage
Electrodes which are not to be used for a longer period of
time should be removed and stored according to storage
instruction described in section 6.2.2. of IM12B06J02-00EN-P.
4. Dimensions
For electrode dimensions refer to IM12B06J02-00EN-P
5. Spare parts
Spare parts are listed in table 2.
