1. FEATURES

* 3 ranges, 2,000/20,000/100,000 LUX. * LUX & Foot Candle unit selection with default. * Auto range for light measurement. * Spectrum of photo sensor meets C.I.E.. * Light measurement with zero adjustment by push button. * Separate probe, easy for operation of different

measurement environment.

* Measure White, Red, Yellow, Green, Blue, and Purple LED

and Standard Lighting in Lux or Foot-Candle units. * Type K, Type J thermocouple thermometer. * Real time SD memory card Datalogger, it Built-in Clock

and Calendar, real time data recorder , sampling time set

from 1 second to 3600 seconds. * Manual datalogger is available ( set the sampling

time to 0 ), during execute the manual datalogger

function, it can set the different position ( location ) No.

( position 1 to position 99 ). * Innovation and easy operation, computer is not

need to setup extra software, after execute

datalogger, just take away the SD card from the

meter and plug in the SD card into the computer,

it can down load the all the measured value with

the time information ( year/month/date/

hour/minute/second ) to the Excel directly, then

user can make the further data or graphic

analysis by themselves. * SD card capacity : 1 GB to 16 GB. * LCD with green light backlight, easy reading. * Can default auto power off or manual power off. * Data hold, record max. and min. reading. * Microcomputer circuit, high accuracy. * Power by UM3/AA ( 1.5 V ) x 6 batteries or DC 9V adapter. * RS232/USB PC COMPUTER interface.
