PCE-LS series ( clase II)
densimeter
with internal calibration, graphic display, multi-language
menu, RS-232 interface and optional software.
Weight range of: 0 to 500
or 0 to 3000g / Resolution : 0.001g / 0.01g

The PCE-LS series densimeter
is attractive due to its high level of accuracy and its
multi-functions. It is an exceptional device with its
durable cast aluminium enclosure. The graphic display
with capacity indicator makes results easy to read. With
the optional software application, data can be
transferred to a computer by way of the RS-232 interface.
If you only have a USB port, then we have a seperate RS-232
to USB adaptor available. The device is has an internal
automatic calibration feature or an external calibration
can be performed with optional test weights (only in
cases where the densimeter is not verified). The
densimeter can also be calibrated in an accredited test
laboratory to certify that it meets with ISO standards.
There all also a variety of other optional accessories
available for the device.
This
link shows an overview of other densimeters that are
available to meet your needs. Below you will be able to
see the technical specifications of this device. Feel
free to call us to discuss the features of these devices
or any other models we have available. Our technical
department will be have to assess your situation.

Aside from
showing a digital representation of the measured weight,
the LCD also shows a bar to indicate the remaining range
capacity (0 to 100%).
This allows the user to check how much of the
measurement range has been used. The light intensity of
the display backlight can also be adjusted via the
keypad. The image above shows the display of the
densimeter with backlit illumination off.

A
verifiable
densimeter is prescribed for processing
medicine in a chemists'
as well as for analysis in medical laboratories and
pharmaceutical companies. Take into account its wide
field of application. We can verify your
densimeter for you.
The densimeter has a counter which is
officially verified and can
be used for:
a) In comercial transactions where market price is determined by
weight.
b) The manufacture of medicine, including analysis in a medical
laboratory and pharmaceutical company.
c) For determining taxes, tariffs and fines in official cases and
judgements.
d) The fabrication of packaging.
Each densimeter is tested by the relavent governing body
to verify the device meets with retail standards. This
is when the accuracy of the device is confirmed to be
within acceptable standards. The EU validation extends
across all member states of the European Union. |

With this declaration of
conformity, we have a written
document that shows the PCE-LS
densimeter meets with the
specific properties outimed in
the document. This is presented
in different languages according
to the standards met by the
densimeter.

Calibration:
according to the UE 90 / 384 / EWG directives, all
densimeters should be officially calibrated for:
a) In comercial transactions where market price is
determined by weight.
b) The manufacture of medicine, including analysis in a medical
laboratory and pharmaceutical company.
c) For determining taxes, tariffs and fines in official cases and
judgements.
d) The fabrication of packaging.
Each densimeter can be reviewed by the Calibration
Office. This will endsure that the device is functioning
accurately within a specified range of tolerance that is
permitted. Con ello se confirma
su precisión dentro del marco de tolerancia de calibración
permitido. The EU validation extends
across all member states of the European Union.
Calibration
of the densimeter with the CAL adjust programme:
the programme will be identified by an official mark
after the first calibration. The valibration will be
valid for a given period of time. This will require the
device to be associated with the postcode of the
organisation to fascilitate the calibration. Depending
on the model, this calibration can be done by the
manufacturer or onsite.
Calibration
of a densimeter by adjustment or automatic change:
There are no limits when the device is being used onsite,
as the automatic calibration can be done when required
after the initial calibration.
Calibration value: measured as the tolerance of a
calibration, almost always between 1 and 10 days.

|
Software
This software application will allow for transfer of
data to a computer via the RS-232 connector. It will
also include time and date to allow data to be
documented correctly on a computer. Daa can also be
exported to other programmes such as Excel. If your
computer only has a USB port, then the corresponding
adaptor should be used. |
|
|
RS-232 to USB adaptor
AnRS-232 cable is included with the software application.
If you require a USB style connector, then this adaptor
will permit you to connect the densimeter to a USB port. |
|
|
Printer
To print data results directly from the device, to
document weights in a laboratory. It comes with an RS.232
connector and 240V mains adaptor. The papar is 112mm
wide. |
|
|
Official calibration according to class M II
Calibration of this type of densimeter can only be done
by an official body which has authorisation to perform
this task. Once this is done, an annual recalibration
will not be required using an external calibration
weight.
The first calibration is valid for two years, after
which the device will need to be recalibrated annually. |
|
|
ISO laboratory calibration
certificate
For companies that wish to include the thickness meter as
one of their internal tools or for annual recalibrations.
The ISO certification includes a laboratory calibration
and a document with all the measurement values. |
|
|
Device for determining density
This device is used for determing the density of solids.
It uses the hydrostatic principal. Density is the
relation between weight [g] and volume [cm³].
Weight is determined by weighing the test material in
the air. Volume is determined by testing the material
while it is submerged in liquid. |
|
Weight
control
(class EII, 100 or 200g according to OIML) This can
only be used to recalibrate the densimeter in situ and
to allow for quick testing on the devices accuracy. |
