VOC Ranges/Sensitivity
0V or 4mA: BEST, Clean Air
1V or 5.6mA: STANDARD, calibrated level, reference level
10V or 20mA: WORST, polluted air
In normal conditions, base level is equals to 1V.
Lower than 1V is better than calibrated situation.
In some cases, indoor condition may be better than calibrated level.
Higher than 1V is showing polluted air level.
Pollution is measured from 1V to 10V.
Sensitivity for VOC.
Higher response for VOC gasses at HIGH sensitivity.
10V of HIGH is equal to 4V of LOW.
10V of MEDIUM is equal to 6V of LOW.
1V is same for all sensitivities.
Example: 3.0V @ LOW == 4.6V @ MEDIUM == 7.0V @ HIGH
