Minolta Illuminance Meters offer excellent light-measuring capabilities with superb accuracy and simple operation. This is achieved by combining a silicon photocell with a microprocessor for compact, lightweight design. Their convenience and portability are invaluable for the control of lighting in industrial and recreational areas, as well as in laboratory and environmental control applications.
Measuring time can be adjusted for accurate readings of both continuous and flickering light sources. Illuminance deviation between sources can also be determined, or integrated illuminance over a period of time can be calculated. Three models are available, offering different features to meet any user requirement. Minolta Illuminance Meters are ideal for measuring illumination and exposure levels in a wide variety of industrial, recreational, and scientific applications. The Minolta Model T-1 Illuminance Meter, with a metering range of 0.01 to 99,900 lux (0 .001 to 9,990 ft-C), is ideal for measurements in most situations.
