The difference for our three CO2 models :
TL-700 General function,without data recording function.
TL-700PRO datalogger function.All readings can export and record as EXCEL and PDF files
TL-700PRO WIFI with wifi and datalogger function.All readings can export and record as EXCEL only
Carbon dioxide concentration level:
400-450PPM(excellent):usual outdoor air level
450-700PPM(Good)The typical value of living space with good ventilation.
700-1000PPM(Minor pollution)The living environment with poor ventilation.
1000-2000PPM (middle level pollution) insufficient oxygen makes people sleepy and the air that may cause complaint.
2000-5000PPM (serious pollution):The stagnant, old and muggy air. The phenomenon of headache, drowsiness with distraction, declination of attention, tachycardia and slight nausea.
Above 5000PPM (serious pollution): may cause serious anoxia or lead to perpetual cerebral injury, coma or even death when exposing in air.
