Best in class Gas Mixer with unique sonic nozzle technology

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

Users can easily perform precise gas dilution, ozone, and gas phase titration (GPT) calibrations with the Model 4010T Gas Dilution Calibrator. Enhanced with the latest technology, the Model 4010T was designed to set a new standard of quality and performance for a variety of applications in ambient air monitoring including trace levels, continuous emission monitoring (CEM), fugitive emissions, odor and process monitoring. The Model 4010T calibrator uses embedded microprocessor technology to accurately deliver and control gas concentrations, along with multiple curve fits to linearize the desired output for the intended purpose. The unit can be operated manually or automatically to conduct calibrations or audits that exceed U.S. Environmental Protection Agency (EPA) method requirements. Highly accurate mass flow controllers (MFC’s) along with an optional ultraviolet (UV) ozone generator and photometer ensure reliable, repeatable gas concentrations. The Model 4010T can store 20 calibration sequences, with up to 20 concentration levels in each sequence. Local or remote operation is accomplished using the front panel keypad, external keyboard, RS-232 or Ethernet ports. Intuitive, menu driven software allows uncomplicated programmability and access to real-time diagnostics.

The Model 4010M is a simple, but powerful Intelligent Multi-gas Dilution Calibrator that can easily perform gas dilution, multi-source gas blending, ozone generation, and gas phase titration (GPT = NO + O3 => NO2) for environmental, laboratory, or point source monitoring.

The Model 2020-EXP is a portable source for clean, dry air designed to meet a wide range of requirements for the environmental industry including trace level applications. From supplying zero air for calibration systems to purge air for permeation ovens, the small package size and weight make the Model 2020-EXP the preferred choice for field and audit personnel as well as operating environments with limited bench space. The Model 2020-EXP 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 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.
