Measure and log carbon dioxide (CO2) content, air temperature and relative humidity all at the same time with this triple-function datalogger from Extech.
Supplied as standard with a dual-wavelength, maintenance-free NDIR (non-dispersive infrared) sensor, the Extech SD800 will measure all three parameters simultaneously and display them on the large-size LCD screen.
The Extech SD800 is a datalogger; it is supplied as standard with 2 GB SD card which can store a wide range of different records. It's also possible to configure the rate at which the logger captures a measurement; choose between 5, 10, 30, 60, 120, 300 or 600 seconds or alternatively use the Auto mode.
All records stored on the SD800 are date and time stamped and can be transferred to PC for further analysis using Extech's free software (available as a download on the Extech website or in Excel.
The SD800's measurement range is 0 to 4000ppm when measuring CO2, 32 to 122°F (0 to 50°C) when measuring temperature and 10 to 90% RH when measuring humidity levels. The Extech SD800 is most useful when used as a continuous measurement tool due to its ability to datalog readings.
