Lux meters
Lux meters for measuring brightness in lux, fc or cd/m². Some lux meters are equiped with internal memory or a data logger to record the measurments. The measurment of light intensity with these lux meters are, each day, becoming more important in the workplace where protective screens are needed. The technique of measuring enviromental conditions, to which the measurement of light belongs, also occupies a lead position in scale of importance. Lux meters with data loggers as shown inour on-line store, are highly regarded especially due to their cosine correction of the angle of incident light. These lux meters have memory to store measured values, and software to analyse readings. We also offer a meter for measuring UVA radiation. Frequently we are asked about conversion between different measurement units. The following link contains information for: conversion of different measurment units for lux meters. If you require more information, you can view our page outlining typical illumination standards or if you don't find the lux meters you are looking for, please contact us and we will help you find the best solution to suit your needs by calling our offices on: +44 ( 0 ) 191 377 3398 and our technical staff will advise you regarding our products.

The FNL (German institute of Standards) has extensive information about measuring light in the workplace. The commission for the standardisation of technical lighting in DIN is concerned with the DIN standard in respect to natural and artificial ultraviolet light, visible light and infrared. The FNL makes determination about the following areas: terminology, basic visual requirements, fotometría, all applications of interior and exterior illumination and the photo biological effects of light and radiation.

Due to numerous requests relating to the lux meters and measured brightness, we have formulated in a table a series of accepted minimums that should be maintained for different indoor situations or locations. In regards to the outsdoors, substancally higher values are given, for example, 30,000 lux or 200,000 in sunlight. These values are for reference purposes only and PCE Group does not guarantee their accuracy.
