2.14 Testing Incubators (2820)
When testing incubators with the Model 2820, it is important to keep
moisture from entering the instrument. Moisture can contaminate the IR
cell and affect the readings.
A desiccant filter is provided with the instrument to remove excess water
vapor (humidity), refer to Section 2.5. When testing water-jacketed
incubators, however, the potential exists to draw condensation—water
droplets that form inside the incubator’s internal sample line—through
the desiccant filter and into the instrument.
Bacharach offers a water trap as an accessory (P/N 19-3265) to help
prevent water from being drawn into the instrument. It is used in-line
between the incubator and desiccant filter as shown in Figure 2.
Important! Remove the water trap’s internal particulate filter
element before testing.
