LV CALIBRATION

Our motivation is excellence in metrology. For this reason, the LCOE has been for more than 70 years a national benchmark in the calibration of low voltage measurement instruments. Two key factors support our work, the high qualification of our technicians and the most accurate measurement systems.

LCOE's calibration services scope from high-precision standards to industrial measurement systems. We conduct a periodic review of our calibration procedures to guarantee our customers the lowest calibration uncertainty. To consult our CMCs accredited by ENAC, see the following link: Nº1/LC10.001

ELECTRICITY DC & LOW FREQUENCY

Knowledge, research and expertise are essential to developing metrology on constantly evolving areas such as electricity.

Accurate energy easurement is essential for utilities, businesses and consumers. The safety of the facilities is based on accurate and precise measurements, that is why the main transformer manufacturers, facilities inspection companies and industrial laboratories trust LCOE for the calibration of their measurement systems such as:

Passive standards (resistances, capacitors and inductances), high-resolution multimeters and calibrators, current and voltage transformers, transformer ratiometers, RLC bridges and the most of electrical measurement equipment in a wide measurement range.

OPTICS

The precision in the measurement of light is very relevant in both exterior and interior lighting.

Photometry applied to the lighting of public roads, tunnels, accesses, etc. It has implications for road safety. In Spain, the REEAE regulation and RD 1890/2008 regulate light limits outdoors.

In interior lighting, photometry is applied to the health of workplaces, both in offices and in industry, where light limits are required with consequences on occupational health and safety (EN 12464).

The LCOE optics laboratory offers calibration services for lux meters from 0.4 lux to 5000 lux and luminance meters from 1.8 cd / m2 to 1000 cd / m2.
