here the value is 0xD1 = 209
it's a cairsens CAV ( NH3 25ppm ) : measure = 209*100 = 20900pbb = 20.9 ppm
for a cairsens CHM ( H2S 1ppm ) : measure = 209*4 = 836pbb = 0.836 ppm
for a cairsens CCM ( O3 1ppm ) : measure = 209*4 = 836pbb = 0.836 ppm
for a cairsens CSM ( SO2 1ppm ) : measure = 209*4 = 836pbb = 0.836 ppm
