Testing and Calibration

The manufacturing processes carried out by Centronic require testing of both sub-assemblies and the completed equipment.

Centronic maintains several radiation sources at its Croydon site for testing and calibration of radiation monitoring equipment.

Neutron detectors, for use in nuclear reactor instrumentation and other high neutron flux applications, are routinely calibrated by Centronic at the CONSORT reactor operated by Imperial College London.

Centronic has in-house capabilities for carrying out helium leak testing and pressurised testing of vacuum tight envelopes.

Electrical testing, e.g. insulation resistance measurements and high voltage breakdown, is also a common requirement in manufacture of Centronic products.

Nucleonic and electrical testing is routinely carried out at temperatures of 450°C to 500°C

Centronic photodiodes and Solatell instruments are calibrated for spectral sensitivity using primary standards calibrated by the UK's National Physical Laboratory (NPL).

Electro optical characterisation of photodiodes. Tests can include calibration, spectral responsivity, rise time, capacitance ,dark current and shunt resistance measurements.

Qualification testing to customer specific requirements, including mechanical and environmental conditioning.
