Integrity test device TechnoCheck®-3

I am interested in TechnoCheck®-3 Please call me back

TechnoCheck®-3 is an automatic device for testing the integrity of membrane filter elements used in biopharmaceutical industry. It has a complete set of all standard tests and allows you to fully test filter elements, both based on hydrophilic and hydrophobic membranes.

The device is designed for testing systems:

  • with cartridges filter elements;
  • with capsules;
  • with flat disk membranes.

Features and applications

In accordance with GMP requirements, it is necessary to check the integrity of the membrane-based filter elements in order to ensure the quality of manufactured products. 


Technofilter RME is expanding its product line of automatic microprocessor-controlled integrity control devices of the TechnoCheck® series.

TechnoCheck®-3 device is convenient and easy to use. All necessary information is displayed on the touch screen panel. The results of each test are printed out on the built-in printer. The device implements generally recognized algorithms for testing membrane-based filter elements. The device is connected to the compressed air line and to the filter housing under test using quick-release couplings.

TechnoCheck®-3 features and benefits

  • Full automation of testing.
  • Hight accuracy, fast and reliable measurement.
  • Operational control and indication of results on touch control panel.
  • Fast program selection and data input.
  • User – friendly menu design and online hints facilitate the user operation.
  • The integrated printer for printing test results ensures data storage.
  • Freely programmable test allows testing filters produced by different manufacturers according to individual integrity test parameters.
  • Functions of device integrity and pneumatic system blowing.
  • Mode "Wetting" for hydrophilic membrane-based filter elements.
  • Storing the test results in external USB-flash memory. 
  • Optionally the device can be equipped by QR code reader for express filter’s data input.
  • High reliability of the device ensures long service life.

New features

  • Calibration procedure is significantly simplified. Now the customer can calibrate the device himself. TechnoCheck®-3 is self-calibration device attached with detailed instructions for the calibration procedure. There is no more need to send TechnoCheck®to the manufacturer for calibration. 
  • Technofilter RME can also send a specialist to calibrate the device at the customer's enterprise.
  • Remote connection to the device is now as easy as communicating via Skype - no need to know the IP address, configure the router, deal with network layers, ports, protocols, and non-standard connections. The EasyAccess 2.0 technology used in the device allows you to remotely access and control the device connected to the Internet via an enterprise local network, 3G or 4G router. You can control the device using a remote computer or tablet.
