The Fieldpiece SRS3P Wireless Refrigerant Scale combines modern wireless electronics and rugged materials to perform at the high level you demand. The platform is made of thick aluminum to maintain accuracy over the life of the product. Rubber bumpers and pad cushion both the tank and the scale itself. Platform electronics are sealed to block the occasional moisture seen from rain and splashing. A new wireless protocol sends platform measurements to both the remote display (sold separately) and the Fieldpiece Job Link mobile app.
