Figure 4 Sensitivity Long Term Stability
1400
Figure 4 shows the excellent long term stability of the H2S-A1 which results from the combination of a patented design, superior electrochemistry and good process control.
Sensors were stored in extreme humidity/ temperature conditions, simulating real usage.
