1. FEATURES
* Short wave 254 nm ultra-violet irradiance measurement.
Professional UVC light meter, used to measure the
UVCirradiation value under the UVC light source.
source.
* Two ranges : 2 mW/cm^2, 20 mW/cm^2.
* UVC Light sensor with cosine correction filter.
* UVC function build Zero button.
* UVC light meter have the wide p application especially
for the medical field.
* Microprocessor circuit provides high reliability and
durability.
* Separate UVC LIGHT probe allows user to measure the
UV light at an optimum position.
* 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.
