The T630 is a dedicated, compact 31?2 LCD digital light-meter. Illuminance is measured in Lux (Lumen per square meter) and is the amount of luminous flux (Lumen) per area at a point. The meter has a CIE photopic spectral response that evaluates the Lux closely to the capability of the human eye. The T630 has a detachable sensor head with a 1.5m cable and a sensor cover.
