Our metrology and calibration services

These services concern the fields of electromagnetic compatibility and mechanical and climatic environments.
Our Emitech and Environne'Tech metrology and calibration services have been developed at the same time as our testing laboratories. They have been created to meet our internal needs and contribute to the Cofrac accreditations of our laboratories.
Furthermore, our Emitech metrology laboratory has itself been awarded .
Developed on the basis of expertise acquired within our group, Emitech’s metrology and calibration services are made available externally to manufacturers equipped with their own laboratories and sharing the same stringent requirements as our own laboratories.
Shared expertise
Cofrac-accredited calibrations of equipment specifically used for EMC testing:
- SAC or FAR chamber (ANE/SVSWR validation)
- rejection filter, high-pass, low-pass, band-pass filters, etc
- CISPR 25 chamber
- transient limiters
- ESD generators pursuant to the EN61000-4-2 and ISO10605 standards
- attenuators
- loads
- preamplifiers
- tests leads
- LISN pursuant to the following standards: CISPR16-1-2, CISPR25, ISO7637-2, DO-160, MIL-STD461, etc.
- CDN pursuant to EN61000-4-6 standard
- antennas (biconical, BicoLog periodic, log-periodic, horn, log-spiral, dipole, whip): Measurement of antenna factor (pursuant to CISPR 16-1-4 and CISPR 16-1-6, ANSI C63.5 or SAE-ARP958) and VSWR
- loop antennas or magnetic field loops pursuant CISPR 16-1-6: Measurement of antenna factor or conversion factor
- electric or magnetic field probes: Measurement of correction factor
- calibration JIG
- current injection clamps
- current clamps : transfer impedance measurement
- couplers
While our accreditation guarantees a recognised level of quality, we also perform calibrations outside the scope of the accreditation:
- amplifiers
- synthesised generators
- EMC receivers and spectrum analysers
- milliwattmeters
- fast transient generators, coupling networks, capacitive clamps and combined generators (pursuant to EN61000-4-4, EN 61000-4-5 and EN 61000-4-11)
- shock wave generators, coupling networks (pursuant to EN61000-4-5)
- absorber clamps
- CMAD clamps
- coupling clamps (EN 61000-4-4) and decoupling clamps (EN 61000-4-6)
We can carry out certain services directly on our clients’ premises:
- Validation of test sites (sites in open environments, semi-anechoic cages or FAR rooms): NSA, VSWR (according to CISPR16-1-4, ANSI C63.4, ETSI TR 102-273-2/3/4)
- Verification of Faraday cage performance: field uniformity (EN 61000-4-3), shielding efficiency (EN 50147-1, IEEE, etc.)
As we fully understand laboratories’ needs, we offer quick turnarounds to minimise your downtime.
Calibration:
- accelerometers and their conditioners
- force sensors
- pressure sensors
- temperature sensors
As we fully understand laboratories’ needs, we offer quick turnarounds to minimise your downtime accompanied by highly accurate automated traceability of the accuracy of measuring instruments to minimise the uncertainty of measurements.
Optimised monitoring
At the end of our service, we provide you with a calibration certificate and schedule your next intervention.
