The Model 2500 permeation oven is a simple, effective tool for generating precise gas concentrations for calibrating air quality analyzers, source monitors and other measurement equipment. When combined with our gas dilution calibrators, it creates a powerful and intelligent calibration system. The Model 2500 permeation oven chamber is large enough for many types and sizes of permeation tubes. A front panel mounted precision pressure regulator, reference pressure gauge, temperature controller and oven inlet give the operator easy access to the unit controls at all times. Carrier air is provided by the Model

The Model 2030 Portable Ozone Transfer provides an accurate and convenient means of measuring low levels of ozone in ambient air. Using the Beer-Lambert law, ozone is measured in a single photometric cell by detecting the absorption of ultraviolet (UV) radiation from ozone molecules at a wavelength of 254 nm. Real-time comparison of the UV light intensity for the sample gas to the reference gas yields a precise concentration of ozone. The single cell design reduces the complexity of the ozone measurement and automatically eliminates zero drift. Advanced, easy to use, menu-driven software allows access to sample conditions and diagnostics and the strip chart feature allows the user to view a time series plot for ozone readings. The 2030 Portable Ozone Transfer offers a bright color display, data logging capability and advanced communications via Ethernet, USB and RS-232/485.

The Model 1001 Zero Air Source is designed to meet the requirements of clean, dry air for dilution calibrators, purge air for permeation tube ovens, supply air for test chambers and pollutant free air for other laboratory or environmental applications. Equipped with dual coalescent filters and a permeation drier, moisture removal is enabled automatically using adjustable control circuitry or manual purging from the front panel. Additionally, upon completion of calibration, the air source can be controlled automatically by a Sabio dilution calibrator or remotely by contact closure or when installed on demand with an internal pressure switch. Air pollutants are removed using reusable dual rear mounted scrubber canisters for NO, NO2, O3, SO2, H2S. Other pollutants such as carbon monoxide (CO) or hydrocarbons (HC) can be removed with an internal oxidizer. Both types of internal oxidizers come equipped with front panel mounted temperature controllers which monitor and control the temperature for optimum performance.

The Model 2020 is a portable source for clean, dry air designed to meet a wide range of requirements for the environmental industry. From supplying air for calibration systems to purge air for permeation ovens, the small package size and weight make the Model 2020 the preferred choice for field and audit personnel as well as operating environments with limited bench space. The Model 2020 uses an internal permeation drying system for moisture removal and is coupled with filter canisters for scrubbing NO, NO2, O3, SO2, and H2S. Optional features such as the internal carbon monoxide (CO) oxidizer or external hydrocarbon (HC) oxidizer further the Model 2020’s clean air capabilities.

The 2010D Intelligent Gas Dilution Calibrator can easily perform gas dilution, multi-source gas blending, ozone and gas phase titration (GPT - NO + O3 to generate NO2) for environmental, laboratory, or point source monitoring. The Model 2010D represents the latest generation of calibrator technology for environmental, laboratory or point source monitoring. The unit has two internal mass flow controllers (MFC's), with options for an internal Ozone generator and a photometer (5.25 inches high and weighing less than 25 lbs). The Model 2010D calibrator uses embedded microprocessor technology to precisely deliver and control gas concentrations along multiple curve fits to linearize the desired outputs for the intended purpose. The unit can be operated manually, automatically, or semi-automatically by remote access. It also has the capability to produce and store in memory 20 calibration sequences with up to 20 levels of source/dilution in each sequence. Users can choose either the front panel membrane keypad, external keyboard, serial port, or Ethernet to input calibration sequences. The instrument’s pneumatic system uses Mass Flow Controllers to precisely meter gas streams and implements multiple types of curve correction algorithms to linearize calibrations. A second source MFC can be added for a wider dynamic range or trace level applications. An optional second source MFC with blending allows user-performed interferent testing and evaluation. Calibrator design exceeds US EPA calibration method requirements. Dilution components are calibrated with standards and test equipment traceable to the National Institute of Standards and Technology. Sabio's calibrators allow the user to view the value of NO2 generated during GPT and displays the dilution of all gases present when using a multi-blend cylinder.

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.
