A DEVICE FOR AUTOMATICALLY CONTROLLING THE CONCENTRATION OF GLYCOL VAPORS IN THE AIR.
A device for automatically maintaining any desired concentration of triethylene or propylene glycol vapor in air is described. It can also be used to measure very rapidly the glycol content of room air. This instrument should greatly facilitate tests of the efficacy of glycol vapors in preventing air-borne infections.
