Organization of this manual
This manual describes the features and operation principles of the light scattering
type liquid-borne particle sensor KS-19F. For information regarding the operation
of other equipment in the case of incorporating the KS-19F into a measurement
system with other equipment, always make sure to refer to the documentation of
the other equipment. The following pages contain important information on safety.
Be sure to read this part.

WARNING
Types of sample uids and cleaning uids
The unit is designed for measuring the particle number concentration in
liquid. The particle count is determined for various sizes.
Never use the unit with the liquid types listed below, to prevent false mea-
surement and the possibility of accidents and damage to the unit.
- Explosive liquid or mixtures containing explosive uid
- Liquid with a temperature of less than +15°C or more than +35°C
- Liquid with a pressure of more than 300 kPa (gauge pressure)
When using different types of sample uid where mixing can lead to reactions
such as thermal build-up, hardening, or particle generation, always perform
thorough cleaning to ensure complete replacement.

WARNING
Sample uid danger prevention
When toxic sample uid comes into contact with any part of the human body
or when toxic gases generated by the sample uid are breathed, there is a
danger of severe injury or death.
When sample uid comes into contact with other objects in the vicinity, there
is a risk of re, explosion, corrosion, deformation or other effects. Observe the
following points closely to prevent leakage and adherence of sample uid.
• In case of accidental contact with any potentially harmful uid, immediately
wash the affected part with plenty of water and contact a physician.
•Do not pass sample uids which can cause corrosion of uid-contacting
parts (PFA and sapphire) through the system.
•Observe the following points when setting up or dismantling a measure-
ment system.
- Check for any possible risks or toxicity of the intended sample uid.
- Take any required steps to prevent sample uid leaks, spray, or ex-
posure of the body to sample uid.
- Always use protective measures such as wearing dual gloves when
connecting or disconnecting tubes and connectors. Dispose of gloves
which have come into contact with uid in such a way that the gloves
do not come into contact with persons or equipment.
- Do not exert strong force or bending stress on tube joints to prevent
leaks.
- As far as possible, tubes and other piping parts should be built up as
a xed installation.
- Do not start to pass sample uid through the system before all con-
nections have been checked.
- This unit incorporates a leak sensor or other safety device, but to
verify safety you should always perform a thorough leak check before
starting operation. To ensure that the leak sensor operates properly,
the unit must be placed on a horizontal surface (inclination within 2
degrees; see page 2).
vi
•The pressure of sample uid passed through the unit may not exceed 300 kPa
(gauge pressure). Ensure that the supply system (sampler, sample uid lines
etc.) has sufcient pressure resistance.
•When using sample uid which may generate harmful gases, provide
adequate ventilation as prescribed by applicable laws and regulations.
• Before and after measurement, clean the entire sample uid system
thoroughly to remove any remnants. Otherwise unwanted effects such as
thermal build-up, hardening, particle accumulation etc. can occur. This is
especially important to prevent the possibility of serious accidents when
using the unit to measure different types of sample uids.
• After use, perform purging while observing any precautions regarding
the mixing of uids. As the last step, purge with pure water and verify
neutrality (pH7). Then ll the unit with ethyl alcohol and seal it.
• Dispose of waste sample uid only as prescribed by applicable laws and
regulations.
• Never mix waste sample uid with other substances unless absolute safety
has been established.
• Always follow the sequence: purging, measurement, exchange, measure-
ment
When using uids of different properties, always thoroughly purge
the uid system, and verify complete exchange before starting the
next measurement. This is to prevent unwanted effects such as sudden
thermal build-up, hardening, particle accumulation etc. that can be
caused by mixing. If this precaution is not properly observed, there
is a risk of a serious accident.
vii
• Pay attention to measurement, exchange, purging sequence
Some uids may be subject to emulsication, temperature rise, or other
effects when mixed with water. In some combinations, hardening or
precipitation may also occur. Before introducing sample uid, make
sure that there is no possibility of a chemical reaction.
Some possibly hazardous combinations and their effects are listed
below. (This list is not comprehensive. There may be other hazardous
combinations as well.)
• Water and sulfuric acid
A high-temperature reaction will occur.
• Oxidizing substances and reducing substances
Example: nitric acid and isopropyl alcohol
A violent reaction (explosion etc.) will occur.
• Acidic and alkaline substances
Example: introducing ammonia water after nitric acid is pro-
hibited
Damage and stress due to neutralization heat and reaction
heat may occur.
Always purge with pure water in between.
• Water and oil, water and organic solvent, or oil and organic
solvent
Emulsication may occur.
Purge with plenty of ethyl alcohol (followed by n-hexane
if required).
[Note]
The above information has been compiled by Rion to the best
of our knowledge, but it does not cover all possible cases or
applications. Be aware that other risks or dangers may exist
depending on usage conditions.

WARNING
The unit uses a laser source
This unit is designated as a class 1 laser product
according to IEC 60825-1 (2014). The internal
particle detector mechanism uses a laser, but it is
fully shielded so that the beam cannot exit from the
enclosure. The identication label shown at right
is afxed to the top of the unit.
Laser Precautions
The particle detector mechanism in
this unit uses a laser classied as a
class 4 laser product according to IEC
60825-1 (2014). The laser source beam
and scattered light can cause blindness
if viewed directly, and can cause skin
injuries if the skin is exposed directly
to the beam and scattered light.
Never open the cover, because this involves the risk of exposure to the laser
beam.
The warning label shown at right is afxed to the top of the unit.
Caution
Use of controls or adjustments or performance of procedures other than those
specied herein may result in hazardous radiation exposure.
CLASS 4 LASER RADIATION WHEN
OPEN AVOID EYE OR SKIN EXPOSURE
TO DIRECT OR SCATTERED RADIATION
(800mW CW SOLID-STATE LASER 532nm)
