Yeah CO, NO2 and SO2 need calibrations to give back the right values and test gas is expensive to buy when I checked and test equipment is't cheap...
I am more interested if the values go up or down so no need for calibration. for them. how much extra would it cost to add them?
about outdoor is that possible with a other case?
