BEKO TECHNOLOGIES can measure to ISO standards 8573-1 class 1


BEKO TECHNOLOGIES can now measure compressed air to ISO 8573-1 class 1 of the ISO standards. This is extremely important for industries such as food & beverage, pharmaceutical, medical, automotive and many more. BEKO TECHNOLOGIES have a portable test rig which comprises of the following four components:-

  • METPOINT OCV system for the measurement of hydrocarbon levels downs to 0.003 mg/m3, which allows for accurate measurement well below the class 1 standard of less than 0.01 mg/m3.
  • The METPOINT dewpoint sensor capable of reading down to -100c pdp which is also well below the class 1 for Moisture of -70c.
  • METPOINT BDL an innovative graphic display for the recording of the parameters for compressed air and gas applications.


  • Lastly we have a laser particle counter. This measures at 0.1, 0.5, and 1 micron particle sizes as per the ISO 8573 requirement, which allows the compressed air particulate contamination to be measured and classified as low as class 1 particulate.

How it works: The Portable Tester is connected into the customers compressed air supply. The level of filtration and drying is then checked and confirmed that it has been sized to achieve a minimum of class 3 for particulate, class 4 for moisture and class 2 for hydrocarbons. This is done to ensure the unit is not contaminated. We then run the portable tester for a minimum of 1 hour, at a flow rate of a minimum of 1 m3/min, this allows the METPOINT OCV to get up to temperature, the dewpoint sensor to dry down, and the particle counter to purge itself and the pipework.

Once the readings are stabilised, they are fed into the METPOINT BDL data logger then are recorded on a comprehensive test data sheet with classification findings. The results are then given to the customer with recommendations.

We will be showing our portable air tester at the Air-Tech show 12-14th March and Foodex exhibition 18th-20th April. Please come and see us.
