Multi-Gas Calibrator, Model 146i



A Change Is In The Air!

The Thermo Scientific 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 multi point measurements. The design of the Model 146i meets or exceeds all published U.S. Environmental Protection Agency requirements for multipoint calibration, audit level 1 and 2 span and precision checks.


   Product Detail


The Model 146i 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 can be operated remotely by a data logger or perform multi point calibrations.
