146iQ is a dynamic gas calibrator used for multi-point calibration of air quality analyzers (NOx, SO₂, CO, O₃, H₂S). It mixes zero air and span gas at a precise ratio through mass flow controllers to generate calibration gas at a known concentration.
With options such as NO₂ generation by gas phase titration (GPT), an ozone photometer and an internal permeation oven, it offers wide calibration capacity on one instrument.
146iQ features
- Gas phase titration and ozone photometer options
- Use of a permeation source with internal permeation oven
- Three or six span inputs (depending on configuration)
- Mass flow controllers for zero air and span gas
- Serial RS232/RS485 communication
- 220-240 VAC, 50/60 Hz supply
