Calibration gas standards generator is now automated

Automated calibration gas standards generator is an update of the manufacturer’s 491M manual system. The new 491Fle generator uses permeation (or diffusion) tubes as the component compound source for creating very low concentration mixtures. It retains the modular construction and expandability of the older model, but replaces the analog controls with the same controls developed for the computer controlled FlexStream system. Product differences include automation, parameter readability and expandability. The new system uses electronic mass flow control and full PID temperature control. KIN-TEK Analytical
