1. FEATURES
* Real time recorder, save the data into the SD memory
card and can be down load to the Excel, extra software
is no need. User can make the further data or graphic
analysis by themselves. under the Excel software.
* At the same time, the SD memory card can record 3
probe's data ( %RH/CO2/O2/Temp. or
%RH/CO2/CO/Temp. ) along with the time information
into the one Excel file at the same time.
* Manual datalogger is available, during execute the
manual datalogger function, it can set the different
location no. ( position 1 to position 99 ).
* Air quality measurement application, multi-function :
CO2 (Carbon dioxide ), CO ( Carbon monoxide ), O2
( Oxygen in air ), Humidity, temperature measurement.
* CO2 range : 0 to 6,000 ppm x 1 ppm.
* O2 range : 0 to 30.0 % x 0.1 %, optional probe.
