Thermo Scientific Model 146i Multi-Gas Calibrator

Pine Item #54946

The Thermo Scientific Model 146i Multi-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 Thermo Scientific Model 146i calibrator meets or exceeds all published U.S. EPA requirements for multipoint calibration, audit, Level 1 and 2 span and precision checks. Options include Gas Phase Titration, UV Photometer, and Permeation Oven. The mass flow controller, ozone generator, permeation tube oven, power supply, and solenoid valves 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 microprocessor 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 calibrator can be operated remotely by a data logger to perform multipoint calibrations.
