/Humidity/Temp. Monitor, SD Card Real Time
Datalogger, Patent
●
Monitor with real time datalogger, save the measuring data along
the time information (year, month, date, hour, minute, second) 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.
●
Show CO2 (Carbon dioxide), Humidity and Temperature value in
the same LCD.
●
NDIR method principal for CO2 (Carbon dioxide) measurement,
available for long term operation. high repeatability and high accuracy.
●
0.1 %RH resolution for the humidity reading, 0.1 degree resolution
for the Temp. reading.
●
Used the precision capacitance type humidity sensor, professional
and high accuracy.
●
SD card capacity: 1 GB to 16 GB.
●
Large LCD display, easy readout.
