Measuring Instruments
T-10 Series
Illuminance Meter T-10 for standard illuminance measurements and T-10M for small-surface illuminance measurements
Used for measurements of a wide range of illuminance.(0.01 to 299,900 lx, 0.001 to 29,990 fcd)
<Notes on the shape and size of the mini receptor>
The shape of the mini receptor head units (T-10M, T-10WL and T-10WS) was changed in May 2008; the size is approx. 1 mm higher than the existent units. When the mini receptor head unit is used in a measuring range of less than 50 cm, note that the displayed value may be different from that of the existent unit by several percent.
