How does it work?
By subscribing to the TSI Tempo™ program, customers commit to a 5-year term with a monthly fee. After enrollment, they will receive a TSI PortaCount™ Respirator Fit Tester—either the 8040 or 8048 model—ready to use. Before the calibration due date at the end of year one, TSI will proactively send a pre-calibrated replacement device to the customer’s site, along with a pre-paid shipping label for returning the old equipment.
With the box and label provided, customers are required to return the old device within two weeks.
This process repeats each year, with TSI proactively sending a replacement device before the calibration due date, and the customer returning the old device. At the end of year 5, the customer may choose to renew the TSI Tempo™ program or end it after returning the equipment for the last time.
