Note:

The numbers printed on the bar sticker are not the actual part numbers of the sensors.

The sensors are visually distinguished two ways:

1. There are coded pegs by the electrical plug connection (see figure 1). One peg (A) indicates the old style and two pegs (N) indicates the new

style.

2. The air sampling port is manufactured differently (see figure 2). A straight bottom (A) indicates the old style and curved bottom (N) indicates

the new style.
