Light Meters
Light meters for measuring brightness in lux, fc or cd/m². Some light meters are equipped with internal memory or a data logger to record the measurements. The measurement of light intensity with these light meters is becoming more and more important workplaces where protective screens are needed to avoid risk. Therefore, light meters are very important when it comes to determining good light conditions in laboratories, schools or PC workstations in order to guarantee optimal results. Light meters with data loggers which you can find in our online store, are highly regarded especially due to their cosine correction of the angle of incident light. These light meters have memory to store measured values, and software to analyse  readings after they are taken. Moreover, some of our light meters come with data interfaces as RS-232 in order to guarantee a data tranfer to a computer, where further data analysis can take place. 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 measurement units for light meters.
If you require more information, you can view our page outlining typical illumination standards or if you can't find the light 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: UK customers +44(0) 23 809 870 30 / US customers (561) 320-9162 and our technical staff will advise you regarding our products. Our engineers and technicians will be happy to help you with the light meters, and of course, with the other products in the field of regulation and control, scales and balances.

Light Meters offer the opportunity to determine light conditions according to several measuring values (Lux, fc and cd/m2). Therefore Light Meters are e. g. part of photo technology to apply sources of light suitably. Light Meters have many more fields of application. Thus, brightness in rooms like offices or halls can be determined via Light Meters. Through resulting values changes in lightning to optimally adapt artificial light sources and solar radiation to requested values can be carried out. Thus, it is possible to measure dark corners with Light Metes to insert them afterwards into the overall concept via adaptation of light sources.

In order to guarantee a measuring accuracy which is always on a high level, all of our light meters are calibration-capable and can additionally be equipped with ISO-ceritfications (optionally available in our online-shop). The certificate either can be acquired when the product is purchased or when the light meter is recalibrated (for example in the course of an annually recalibration). It includes a laboratory calibration and a corresponding certification conforming to ISO standard

The FNL (German institute of Standards) has extensive information about measuring light in the workplace. The commission for the standardization 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, photometry, all applications of interior and exterior illumination and the photo biological effects of light and radiation.

In the following table, you can see the corresponding lux-values which are set for different rooms and types of application:
