LN Industries - Portable gas calibrator with GPT and internal zero air generator is ideal for calibrating and verifying linearization of air pollution monitors. The precision, stability and reproducibility of the generated mixtures are due to the joint use of critical orifices and the high stability of mechanical pressure regulators. Internal self re-generable zero air generators avoid the use of expensive and cumbersome air cylinders.
