TSI 800197 / 800198 Twin-Tube Sampling Hose

Change to part number: Due to the volume of PortaCount® Respirator Fit Testers sold worldwide and to assist with consumable supply, TSI will continue to supply the Twin-Tube Sampling Hose as an after-market product using the new part number of 800198. The previous number 800197 will continue to be used but only as part of the kit when supplied with the PortaCount® Respirator Fit Tester. Please contact your Kenelec Scientific Sales Engineer if you have any questions regarding these changes.
