Precision Scale PCE-LS Series (Legal For Trade / Class II)
Weight range from 0 up to 500 g or 3000 g / resolution of 0.001 g or 0.01 g /
LCD graphic display / internal, external calibration / RS-232-interface and optional software 

There are two models (LS-500 and LS-3000) of verifiable precision scale. The backlit, high contrast graphic display of this precision scale leads the user safely through the process; lengthy instructions and operator errors are things of the past. All LS models can be calibrated/adjusted automatically by the touch of a key, by a preset time, or triggered by temperature changes. Without the need to handle expensive external weights, these functions support integration in quality management systems. The large weighing platform of the scale can be installed for weighing larger objects. The integrated RS-232 interface enables you (by using the optional software-kit) to automatically send the weighing data to PC. LS Series of precision scales have been designed to meet the needs of laboratories, schools, universities, industry and commercial users, without the high cost implications usually found with this type of scale. This link shows an overview of the scales and balances which will meet your requirements.

In the upper image there is PCE-LS 500 series analytical scale with a round weighing pan with 120 mm diameter.  The lower image shows PCE-LS 300 series analytical scale with a square weighing pan (165 x165 mm). Both weighing pans are made of stainless steel and can be used for different laboratory purposes, production and research.

Apart from the digital reading of the weighing data and the large graphic LCD display, this analytical scale comes with a range strip  (0 ...100 %) to check the range directly. Besides, you can adjust both the intensity and the back light through the keypad. The upper image shows the display of the analytical scale with the back light off.

A verified analytical scale is recommended for preparing medicines in pharmacies as well as for the analysis in medical and pharmaceutical laboratories. So, it is important to bear in mind the scale usage scope. If you wish, a calibration can be carried out by PCE Instruments.
An official verification is required when the analytical scale is used for:
 a) Trade relations when the price of the product is determined by its weight.
 b) Preparation of medicines in pharmacies as well as for the analysis in medical and pharmaceutical  laboratories.
 c) Determination of rates, tariffs and official fines as well as for official  and objective surveys in judgements.
 d) Manufacturing of packages.
Every analytical scale is checked by the official authorized centre to provide it with a verification certificate. Besides, precision is determined within the permitted tolerance framework. EU Verification is valid for all the countries of the EU (European Union).

Calibration of the Counting scale

Calibration: To meet UE 90/384/EWG standards, all counting scales must be officially calibrated if they are used for:
 a) Trade relations when the price of the product is determined by its weight.
 b) Preparation of medicines in pharmacies as well as for the analysis in medical and pharmaceutical laboratories.
 c) Determination of rates, tariffs and official fines as well as for official and objective surveys in judgments.
 d) Manufacturing of packages.

Every scale can be checked by the official authorized centre to provide it with a calibration certificate. Besides, precision is determined within the permitted tolerance framework. EU calibration is valid for all the countries of the EU (European Union).

Scale calibration with CAL adjusting program: The adjusting program is marked with an official mark once calibration has been carried out. Calibration will be valid for the given location. So, it is necessary to provide the postal code. Calibration can be performed in the company or in situ depending on the scale.

Calibration of a scale with adjustment of automatic change: There are not any location limitations of the scale due to the fact that the automatic adjustment can be used after a calibration has been done, i.e. it is not sealed. In this case, calibration will not depend on location.

Calibration value: range of calibration tolerance which is between 1 and 10 d.

Options
ISO Calibration (ISO-PCE-BS)
The calibration procedure includes laboratory calibration process and ISO certification. The customer's name and address are included. These certificates are comparable to NIST and UKAS certificates. They are accepted all over the world.

Software-Kit (PCE-SOFT-LS)
The kit includes a software for transferring the  weighing data to a PC or Portable and RS-232-cable. The transferred data can also be sent to other software such as Excel, etc. The standard software is in English (other languages are available: French, German, etc).

RS-232-USB Adaptor (RS232-USB)
In case your PC or Portable uses USB Interface, you can use the adaptor in connection with the standard RS - 232 Cable. Software (covering the actual drivers) is included.

Printer (PCE-BP)
The printer is used for direct output of weighing data. It will be delivered with RS-232 cable, USB cable, net adaptor and 1 roll of paper.

 - paper width 112 mm

 - thermal paper

 - 230 V/12 V Adaptor

Density Determination Kit (PCE-AB-DB)
Density determination is performed by means of Archimedes principle (buoyancy method), which is also the method used by the density determination kit for balances. This method allows determination of the density of solids, viscous and pasty substances, as well as liquids.
