DUCT OPTION (-DUCT)
The SMART-Sensor
™
with -DUCT option is capable of accurately reading air temperature
flowing within a standard air duct. But, to do so, the proper model with the appropriate
probe length should be chosen. The best model to choose will be the model with the tip
of the probe as close to the centerline of the duct as possible.
The simplest way to calculate the probe length needed is by taking the depth of the duct
and dividing by two. For instance, a 16 inch duct (as measured from the probe penetration
point to the oposite wall) would need an 8 inch probe. See
Table 3 on page 20
for model
number details.
