       The T-10 series offers various models and peripheral devices to enable accurate measurement of illuminance in a user-friendly environment at low costs. The models include the T-10, which uses the standard receptor head, the T-10M, which uses a mini receptor head for measurement in small spaces.
       The T-10 series also allows the user to construct a multi-point illuminance measurement system easily. Up to 30 points can be set. This enables construction of an evaluation system for brightness of LCD projectors, which are becoming popular as a presentation tool.
       The T-10 series can be connected to a personal computer.
