Next-generation Illuminance Meters for next-generation light sources

As the technology for artifical light sources changes, instrument technology to measure light must also change.

Konica Minolta's illuminance meters have long been an industry favorite for measuring both natural and artifical light, offering superb accuracy and ease of use together with special features on some models. Several series of Konica Minolta illuminance meters have been introduced over the years to meet the changing needs of customers and new developments in lighting technology.

Recently, the focus for artificial light sources has been on energy efficiency, and LED light sources are a prime example of the next generation of illumination technology. The brightness of these new artificial light sources is controlled by PWM (pulse width modulation), in which the ratio of lamp on time to off time is changed to vary the brightness of the light source. But PWM technology poses new challenges for conventional measuring instruments.

In response to these new requirements, Konica Minolta has introduced the next generation of its Illuminance Meters, the new T-10A series, maintaining the high portability, ease of use, and superb accuracy of the predecessors while providing the capability to measure next-generation light sources.

Principal applications

The T-10A series of Illuminance Meters can measure illuminance (lx or fcd), illuminance difference (lx or fcd), average illuminance (lx or fcd), illuminance ratio (%), integrated illuminance (lx·h or fcd·h) and integration time (h) for a wide variety of applications, and multiple receptors can be daisy-chained for multi-point measurements such as ANSI lumen measurements for projectors. The mini receptor of the T-10MA and the waterproof mini receptors of the T-10WSA and T-10WLA enable measurements that could not be performed with the standard receptor, such as in tight spaces or even underwater. 
In addition, optional Data Management Software T-S10w (Excel® add-in) enables graphical display of measurement data, multi-point measurements with up to 30 receptors, and more in-depth analysis of measurement data using the various functions of Excel®.
