Minolta T-1 Illuminance Meter
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, 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.
