Analyzer 2825/2830/2835

2.14 Testing Incubators (2825 / 2830)
When testing incubators with the Model 2825 / 2830, it is important to
keep moisture from entering the analyzer. Moisture can contaminate the
IR cell and affect the readings.
When a desiccant fi lter (P/N 0007-1645) is installed, it will remove excess
water vapor (humidity), refer to Section 2.13. However, when testing
water-jacketed incubators the potential exists to draw condensation—
water droplets that form inside the incubator’s internal sample line—
through the desiccant fi lter and into the analyzer.
To prevent water from entering the analyzer, install a water trap
(P/N 0019-3265) in-line between the incubator and desiccant fi lter as
shown in Figure 4.
Important! Remove the water trap’s internal particulate fi lter
element before testing.
