Product Overview
The LV-250R is a PM2.5 sampler. It is capable of mass concentration measurements of
particulate matter (PM2.5) using a filter, based on the interim measurement manual
designated by the Japanese Ministry of the Environment. With this sampler, airborne
particulates in environmental air are sucked in at a constant flow rate via a suction port.
PM2.5 particles (particulate matter with an aerodynamic diameter of 2.5 μm, and a 50 %
cut) passed through an impactor are then captured on a filter. Suction flow rate changes
are minimized by a constant flow rate unit equipped with temperature and ambient
pressure correction features, so the sizing characteristics of the impactor are kept
constant. The temperature of the filter unit is controlled so that it is always within 5 °C of
the external ambient temperature. This prevents revaporization of volatile matter
contained in the PM2.5 particle sample.
Features
The constant flow rate unit keeps the suction flow rate constant, thus maintaining the
sizing characteristics of the impactor.
Automatically corrects the suction flow rate for changes in the external ambient
temperature or ambient pressure.
The suction pump provides a high suction pressure and maintains a stable suction
flow rate even with increases in filter pressure loss.
To prevent revaporization of volatile matter, the temperature of the filter unit is always
controlled to within 5 °C of the external ambient temperature.
The ON/OFF timer feature enables the user to set the sampling start time and stop
time.
Displays the flow rate, time, temperature, pressure and other measurement values.
The measurement values (total flow rate, average flow rate, flow rate coefficient of
variation, ambient pressure, pressure loss, ambient temperature, and filter
temperature) are imported to a PC for display or storage. (A special communications
cable and software are optionally available.)
If a power outage causes a temporary stop, or problems with the flow rate or filter
temperature occur, the time of the occurrence is recorded.
The equipment can use across a wide voltage range, from 100 V to 240 V. If a DC
power supply and cable are available, it can be battery operated.
Note: For use at anything other than 100 V AC, the DC power supply and cable
must be custom-ordered, so contact your Sibata sales representative or
the vendor.

The main unit can be used with a single-phase 100 V to 240 V (85 V to 264 V) power
source. It can be used with voltages other than 100 V. However, the power outlet noted
below will not be compatible. Replace the power outlet with one suited to the
applicable voltage. For safety's sake, contact your Sibata representative or the vendor if
you will be using the equipment at a voltage other than 100 V. Also, be sure to ground
the power supply.
If you are using this product outdoors, be sure that the outlet and extension cord used
are waterproof. This product uses a Panasonic WF7515K waterproof plug. Using a
Panasonic WA3519K waterproof outlet with the same rating as the inlet will ensure that
the plug and outlet section is thoroughly waterproof.
Note: Ensure that the power supply has sufficient electrical capacity. Two to three
times the regular power consumption occurs in the instant directly after startup.
Note: Do not connect the power adapter to a multi-plug power strip. Doing so might
cause electric shock or fire.
Note: Be sure to ground this product. Failure to do so might cause electric shock,
malfunction, or fire.
Note: Check that the power cord is securely connected to the product. If the
connection is loose, it will not be waterproofed, which might cause electric leak
or malfunction.
Note: If you are using it at a different voltage, it may not be possible to waterproof the
outlet installed, depending on its shape. Pay attention to the specifications when
wiring the equipment.

Replacing the PM2.5 Impactor
To maintain the particle-sizing characteristics at 2.5 μm and 50 % cut by using the PM2.5
impactor, mount the impactor filter (a φ37-mm fiberglass filter) in the impactor well
(coarse particle catcher). Then cover the filter surface with a layer of impactor oil to
prevent the re-scattering of coarse particles.
While holding the lower section of the PM2.5 impactor, rotate the upper
section of the impactor counterclockwise. Loosen the screws and
separate the upper and lower sections of the impactor.
Note: The impactor well (coarse particle catcher) is placed on top of the lower section
of the PM2.5 impactor. Be careful not to drop the impactor well when the upper
and lower sections of the impactor are separated.
Separate the upper and lower sections of the PM2.5 impactor well.
Attach the impactor filter (φ37-mm fiberglass filter) onto the catcher at the lower section
of the PM2.5 impactor well. Drop 1 mL of impactor oil onto the surface of the filter to coat
it with a layer of oil.
Reverse the procedure to reassemble the impactor well.
Attach each part carefully, ensuring an airtight seal.
Note: To minimize the re-scattering of coarse particles and changes in sizing
characteristics as the inside of the PM2.5 impactor becomes dirty, replace the
impactor filter and clean the inside of the impactor about once per week. Clean it
with soft cloths or paper, or by using pure water to damp them. If the dirt resists
cleaning with pure water, use ethanol or acetone.
