Analytical scales
We have analytical scales which come with software and a the possibility to read to an accuracy of 0.01mg (more analytical devices are available upon request). Some analytical scales can be verified and have a plastic windscreen and an optional test weight. The interface allows for data to be transferred from the analytical scales to a computer. Further analysis can be done using the optional software kit. Analytical scales 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 scales come with various additional components and ISO calibration certificates. Our engineers are available to help you and assess the scales and balances you might need. Call us on: +44 ( 0 ) 191 377 3398.

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

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

- PCE-BT series analytical scales
  (The analytical scales can be calibrated with different weighing ranges (200 g y 2000 g))

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

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

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

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

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

- PCE-VXI 60/220 series analytical scales 
  (verifiable analytical scales, resolution of 0.01mg, RS-232 port)

Not all the scales previously mentioned can be used as classic analytical scales. We made such a selection of scales because they fit within the scope of analysis. Normally all analytical scales 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 scales frequently have an enclosure which can protect from oscillations due to air flow, calibration programmes and shock absorbers that can eliminate sudden movements. Our scales have all the fundamental prerequisites, depending on the model, and multiple components:

                                                                             
                                Software kit                                 Printer                             Density equipment                        Test weights

Analytical scales are frequently used in the industrial sector as well as in quality control or product development. These scales are also used in research and development, in clinics, technical colleges and universities, typically in their laboratories. Analytical scales 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 scales with a resolution of 0.001mg, you should consider analytical scales 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 scales with an internal adjustment weight. This weight is used for making automatic adjustments to analytical scales. 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 scales 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 scales 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 scales, or you are not sure if you require a verification, contact the Verifications office for your country. Verification of analytical scales can be done when the device is ordered or it can be sent for periodic verifications. Once verified, the scales 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.
