Precision Balance -  PCE-LS Series ( Class II)

precision balance of the upper class with internal calibration, graphic display
menu in several languages, RS-232 interface and optional software 

Weighing ranges of 0 ... 500 and 0 ... 3000 g / resolution 0.001 g, 0.01 g) /

This precision balance LS series is an exceptional instrument. The precision balance has high accuracy, multiple applications and low price. The cast aluminum housing of this precision balance provides strength and stability. The graphic display with power indicator makes easy reading the data in this precision balance. With the optional software package of the precision balance you can transmit data to a PC or laptop. If your computer only has a USB interface, you can request the RS-232 adapter to USB,  we offer it as an option on request. In addition to the automatic internal calibration system, you can perform an optional  external calibration with test weights (only if the balance is not checked). You can also calibrate the precision balance in a control laboratory accredited for it (eg for compliance with ISO) or check it with the responsible agency in your community. Other advantage of the precision balance is for example the equipment to determine density (overall index of all precision balances.), what makes it even more complete.
Here we list the features and technical specifications of this precision balance. If you have any questions about the precision balance (with 3 year guarantee) or other similar models, please call or email us: +44 ( 0 ) 2380 98703 0. Our technicians and engineers will be happy to advise you on this precision balance and of course, with the other products in the field of regulation and control systems, measuring instruments or the balances.

In the upper image , a PCE-LS 500 series precision balance with a round weighing pan of  120 mm diameter is shown.  The lower image shows a PCE-LS 3000 series precision balance with a square weighing pan (165 x165 mm). Both weighing pans have been made with stainless steel and can be used for all kind of laboratory tasks, production and research.

Precision Balance PCE-LS 3000

 - Piece counting function of the PCE-LS:
selectable number of pieces of reference
, change of the piece indicator to weight.

- Internal adjustment program: if a
variation of ± 1 ° C is produced or after an interval of
fixed time, the balance carries out an automatic adjustment (internal weighing ).

- Date and time setting  (you must enter
user-specific code).

- RS-232 data interface for PC to connect
the precision balance to a PC

- Capacity indicator: a bright increasing band
indicates the weight range availability
ment in the precision balance.

- Cast aluminum metal housing 
guarantees high robustness and stability.

- Level to set the the balance properly

- Protection against dust and sprays IP 54

- Measurement of density by an optional density determination equipment.

- Optional official calibration certificate (for
example to comply with DIN ISO 9000).

- An precision balance for professional use.

Characteristics of the balances.

Apart from the digital reading of the weighing data and the large graphic LCD display, this precision balance comes with a range band (0 ...100 %) to check the used range directly. Besides, you will be able to adjust both the intensity and the back light through the keypad. The upper image shows the display of the precision balance with the backlight off.

A verified precision balance is recommended to be used to prepare medicines in pharmacies as well as for the analysis in medical and pharmaceutical laboratories. So, it is important to bear in mind the balance usage scope. If you wish, a calibration, we can carried it for you.
An official verification for the analyticial balance is required when the precision balance 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.
Each precision balance 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 members of the EU (European Union).

Technical Data

Calibration of the Counting balance

Calibration: To meet with the  UE 90 / 384 / EWG standard, all counting balances must be officially calibrated to be 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 balance 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 members of the EU (European Union).

Balance 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 with the location of the balances by means of the postal code to prepare calibration. Calibration can be performed in the company or in the location of the balance depending on the balance.

Calibration of a balance with adjustment of automatic change: There are not any limitations depending on the location of the balance 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: measurement of calibration tolerance which is always between 1 and 10 d.

Optional components

Software-Kit (PCE-SOFT-LS)
The kit includes a software to transfer data to a PC or laptop and a RS-232-cable. The transferred data can also be sent to other calculation software as Excel. If your computer only has USB, you will need the USB adapter.

RS-232-USB-Adaptor (RS232-USB)
The precision balance software comes with data cable RS-232. If you want to submit online data to a laptop or a computer or any other system with memory, you must use this USB adapter (which includes the start-up software).

Printer (PCE-BP)
To print the results of the precision balance directly (eg to document weight data in the laboratory), it comes with a RS-232 printer cable  and a 240 V adapter The paper width is 112 mm.

Verification class II M
The verification of this precision balance can only be made by the official agency in your community. Once the official verification is done, it is not necessary to calibrate the balance with external calibration weight. First verification is valid for two years, then you will need to check the balance annually.

ISO Calibration (ISO-PCE-BS)
For companies wishing to incorporate the precision balance in their internal control group of tools or for annual recalibration. The ISO has a laboratory  calibration with a control document that includes the measured values. You can also include the name of your company or customer information.

Weight control
(EII class, 100 or 200 g according to OIML). This control weight can only be used to recalibrate the analytical scale in situ and to control the accuracy of the balance quickly.

Density Determination Kit (PCE-AB-DB)
The equipment is used to determine the density of solids (solid bodies). It uses the hydrostatic principle. Density is the ratio of the weight [g] with the volume [cm ³].
The weight is obtained by weighing the test material in the air. The amount is determined on the impulse [g] of a proof of material submerged in liquid.
