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.
- Calibrated radiation testing is also available using a gamma cell operated by Centronic Raditec.
- 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.
