Refill tabs can be purchased individually. There is not a kit for all the tabs available. For pricing on the tabs please contact our customer service department at cs@pecosales.com or 1-800-752-8460. If you need to purchase refills for all three parameters it is more cost effective to purchase a whole new kit.
