The Extech Heavy Duty Light Meter enhances accuracy by selecting one of four lighting types: tungsten/daylight, fluorescent, sodium, or mercury. The meter utilizes precision diode and color correction filter, and adjusts for cosine and color corrected measurements. The microprocessor assures maximum accuracy through and Fc range of 200.0, 2000, and 5000Fc and a lux range of 2000, 20,000, and 50,000lux. 

 

The built-in RS232 serial interface provides a connection with the optional Windows Data Acquisistion Software that enables users to display and capture readings on a PC, and set time intervals and alarms. The battery operated datalogger module stores over 8000 readings for later transfer to a PC.
