Model 146 i Multi-gas Reference

Mass flow calibrator with enhanced communication capabilities for ambient air monitoring.

Key Features A change is in the air Ethernet connectivity for efficient remote access The Thermo Electron Model 146i Dynamic Gas Calibrator supplies precise levels of ozone, carbon monoxide, non-methane hydrocarbons, sulfur dioxide, nitric oxide and nitrogen dioxide or other gases that a user may require. The gas levels are used to calibrate instruments that perform zero, precision and level 1 span checks, audits and multipoint measurements. The design of the Model 146i meets or exceeds all published U.S. Environmental Protection Agency requirements for multipoint cali- bration, audit, Level 1 and 2 span and pre- cision checks. Options include Gas Phase Titration, UV Photometer, and Permeation Oven The Model 146i’s mass flow control, ozone generator, permeation tube oven, switchedmode power supply, and solenoid valves specification are integrated into a single microprocessor controlled unit. This permits easy to use, menu driven software and a consistent set of operation screens for all calibration procedures. Additionally, the micropro- cessor can make many of the necessary calculations, thereby freeing the operator from having to make the calculations in the field or laboratory. If desired, the Model 146i can be operated remotely by a data logger or to perform multipoint calibrations. Enhanced user interface with one button programming and large display screen Flash memory for increased data storage and user downloadable software Enhanced electronics design optimizes product commonality Improved layout for easier accessibility to components Gas Phase Titration for Generation of O3 and NO2
