Illuminance Meters

Illuminance meters (light meters, spot meters or lux meters) are the industrial cousins of photographic light meters, typically with improved accuracy, added functionality, and traceability. An illuminance meter measures the amount of visible light energy falling on to a defined area, using lx or fcd to express that available light as a measure of perceived brightness.

Traceable measurement of illuminance and the colour of lighting is a common requirement in the built environment. Well designed and maintained lighting provides visual acuity, a feeling of safety, creates atmosphere and is common in:

Shops
Restaurants
Offices
Hospitals
Public Transit hubs
Government buildings and more

Konica Minolta supplies a range of instruments for illuminance measurement. Each of the instruments below conforms to standards such as
DIN 5032 Part 7 Class B or Class AA of
JIS C 1609-1: 2006 and can calibrated each year so that your measurement data is traceable.

Konica Minolta’s industrial light meters include additional features including measurement of:

colour temperature,
chromaticity,
colour rendering index,
spectral power distribution,
dominant wavelength and more.

Accurate and traceable measurement of light enables manufacturers, specifiers/designers, installers and inspectors to quantify the light in the environment. Using measurement data the operator can record or report that the lighting is safe, fit for purpose and meets any standards that may be defined by the customer or industry.

Where to Buy

CL-500A

A hand-held illuminance spectrophotometer ideal for the measurement of LED lighting. The CL-500A provides full spectral data from 360-780nm allowing accurate assessment of colour rendering and other measures such as lux and colour temperature that are traceable to international standards.

CL-70F

An entry-level solution for measurement of Colour Rendering Index, spectral irradiance, peak wavelength, tristimulus values, chromaticity, correlated colour temperature, dominant wavelength, excitation purity, illuminance, and difference values.

CL-200A

A cost-effective solution for measuring illuminance and tristimulus colour of light. Measurement data includes lux, CCT, xy coordinates. The receptor can be separated from the main body to exclude operator reflections or shadows from measured data or to chain up to 30 measurement heads in a single system to cover a larger area.

T-10A / T-10MA / T-10WsA

A professional illuminance meter that provides accurate and traceable lux or fcd over a large measuring range. Can be used with a detachable receptor head for remote measurement or in multi-point mode by connecting up to 30 receptors to cover a large area.
