The Mariner® IP67 washdown portion control scale is submersible underwater for easy cleanup. The NSF-certified stainless steel scale offers a dual power source of rechargeable battery power or 120V AC adapter (included) with a watertight AC plug on the side. The unit's digital speed and accuracy means you'll be able to view weights instantly with up to a fine 0.1 oz. accuracy. The system can weigh up to 10 lbs. in pound-ounces, fractional ounces and other options. The model WPS10 features an audible over/under alert for checkweighing and the clearly visible 1.2"/30 mm high backlit blue LCD display offers large 1"/25 mm high bold digits. The compact scale takes up a small amount of counter space: 7.5 in W x 9.75 in D / 190.5 mm W x 247.5 mm D.
