Detecting Specific Gases
Each gas-specific gas detector is shipped factory calibrated to its specific target refrigerant. Refer to
Figure 1-3
and
Table 1-2

NOTE: Emerson recommends not
re-calibrating gas-specific detectors in
the field to a new target gas; purchase a
new gas-specific detector instead. In the
event you prefer not to purchase a new
gas-specific detector, use optional
calibration instructions in Chapter 6 for increased
accuracy when detecting a new target that is different
from the “as shipped” target gas. Refer to the example
in Table 1-3.
