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.

* CO range : 0 to 1,000 ppm x 1 ppm, optional pribe

* Humidity range: 10 to 95 %RH.

* Dew point Temp. and Wet bulb Temp. measurement.

* Temp. range : 0 to 50.0 , / .℃℃℉
