ATP Instrumentation LX-1309 Manual

Ⅰ

Introduction


The digital illuminance meter is a precision instrument used to measure illuminance (Lux, footcandle)

It meets CIE photopic spectral response.

The illuminance meter is compact, tough and easy to handle due to its construction.

The light sensitive component used in the meter is a very stable, long-life silicon photo diode and spectral response
filter.
