Sabio’s Model 2505 Portable Permeation Oven generates precise gas
concentrations for calibration of air quality analyzers, source monitors and other
instruments. The Model 2505 may be combined with the Model 2010 and 4010
Gas Dilution Calibrators to form a very powerful intelligent calibration system.
Carrier air is provided by an internal air supply featuring an inlet filter, quiet
internal pump and rear mounted scrubber canister. A precision regulator and
critical orifice is used to regulate carrier flow through the permeation oven. A 0-15
psig pressure gauge is calibrated to provide carrier flow reference points.
The heart of the Model 2505 is a large capacity Teflon coated permeation
chamber that can accommodate many types and sizes of permeation tubes
concurrently. A front-panel-mounted knurled screw-in stopper is provided for
easy access of the permeation chamber. The permeation chamber is housed in a
precise temperature controlled insulated oven that features a carrier pre-heater,
heaters and RTD sensor.
The oven temperature is precisely maintained by a microprocessor based
temperature controller driving an optically isolated DC control module. Pulse
width modulation is used to regulate the heat cycle to minimize thermal noise due
to heater on/off cycling.
Dual displays on the temperature controller provide direct readout of set point
temperature and actual oven temperature. Oven temperature is maintained
within +/- 0.1 deg. C of setpoint.
The oven temperature control system and carrier air supply are battery backed
for 8 hours of operation.
