Analytical balances
We have analytical balances which come with software and a the possibility to read to an accuracy of 0.01mg (more accurate devices are available upon request). Some analytical balances can be verified and have a plastic windscreen and an optional test weight. The interface allows for data to be transferred from the analytical balances to a computer. Further analysis can be done using the optional software kit. Analytical balances come with multiple functions:
  - Automatic internal adjustment of weight, piece count, ISO GLP protocol, determination of percentage, RS-232 interface.
  - Powered by mains adaptor, software kit is optional.
Analytical balances come with various additional components and ISO calibration certificates. Our engineers are available to help you and assess the balances you might need. Call us on: our offices: +44 ( 0 ) 191 377 3398.

Technical specifications for our balances for analysis can be found at the following links:

- PCE-BS series analytical balances
  (economical analytical balances with weight ranges of up to 300, 3000 or 6000g)

- PCE-LSM series analytical balances
  (verifiable analytical balances, with weight ranges of 200, 2000 or 6000g)

- PCE-LSZ 200C series anaytical balances
  (analytical balances for weighing paper and fabric, range of 0 to 20,000g/m², resolution of 0.1g/m²)

- PCE-LS series analytical balances
  (verifiable analytical balances with internal calibration, graphic display, ranges up to 500 or 3000g)

- PCE-ABZ 200C series analytical balances
  (similar to the PCE-ABZ 100C series analytical balances but with a weight range of 0 to 200g)

- PCE-AB series analytical balances  
  (verifiable analytical balances, internal calibration graphic display, 0.1mg, RS-232 port)

Not all the balances previously mentioned can be used as classic analytical balances. We made such a selection of balances because they fit within the scope of analysis. Normally all analytical balances have a sensitivity of less than 0.1mg. The result indicated in the document of analysis is the value between at least two results with a sufficient repeatability (factor r). Electronic analytical balances frequently have an enclosure which can protect from oscillations due to air flow, calibration programmes and shock absorbers that can eliminate sudden movements. Our balances have all the fundamental prerequisites, depending on the model, and multiple components:

                                                                             
                                Software kit                                 Printer                             Density equipment                        Test weights

Analytical balances are frequently used in the industrial sector as well as in quality control or product development. These balances are also used in research and development, in clinics, technical colleges and universities, typically in their laboratories. Analytical balances are high quality devices and are precise, with resolutions of 0.1mg, and example is the PCE-AB series. The PCE-VXI 60/220 is a scale with a reading capacity of only 0.01mg. If you need balances with a resolution of 0.001mg, you should consider analytical balances which can evaporate liquids. Furthermore, they have protection against air flow and have a level to ensure they are portioned correctly.

In the following image you can see balances with an internal adjustment weight. This weight is used for making automatic adjustments to analytical balances. The adjustment is done automatically, such as every two hours or if a temperature change of ±1°C occurs. This ensures a consistent high level of accuracy. Once the balances are turned on, it performs an internal check of all its functions which is initiated by an electronic component in the device and an adjustment is made by the internal adjustment weight. An ISO certificate with calibration document or a verification which meets with DIN ISO 9000 can be ordered.

Verification: According to CE certifications, analytical balances should be verified when one of the following occurs (as we have just stated, a verification can be done by an authorized verification office or by PCE Group):
   a) In commercial dealings when the price of the product is determined by weight.
   b) In the production of medicines in pharmacies, as well in the detailed analysis in medical laboratories and pharmaceuticals.
   c) For concrete fees, tariffs or official fines. Also for technical expertise in court cases.
   d) The manufacture of packaging.
If you would like additional information about verifying analytical balances, or you are not sure if you require a verification, contact the Verifications office for your country. Verification of analytical balances can be done when the device is ordered or it can be sent for periodic verifications. Once verified, the balances should not be recalibrated with a calibration weight.  The first verification is good for two years at which point further verifications should be done annually.
