A&D Weighing SJ-WP Series checkweighing bench scale

A&D Weighing has launched an NMI trade-approved checkweighing bench scale suitable for high-speed weighing and packing. The innovations of the SJ-WP Series ensure efficiency in both sanitary management and weight measurement.

An externally mounted load cell/weight sensor seals for watertightness without compromising the weighing speed and stability, due to up and down movement of the load cell changing the air pressure inside. As a result, the stabilisation of the series can be as fast as 0.5 s. The stainless steel weighing pan surface is resistant to scratches and wear, and is easy to keep disinfected.

The load cell incorporates a stopper and requires no external components for overload protection. The area around the load cell is therefore unobstructed and easy to keep free from debris. Besides using water from a hose, it is possible to soak the scale directly in water with pH-neutral detergent for thorough washing.

The large-sized characters make the weight values easy to read, even in dimly lit areas. Bright and multicoloured five-step LED comparator lights help the operator judge the results of checkweighing instantly. Comparisons can be made in three, five or seven levels, with no light indicating either end of the continuum.

The scale can perform tare automatically when the weight reaches the set target range and the comparator also functions in negative values. By using this and the auto-tare function together, the user can perform ‘take-away’ checkweighing. The series can handle weights up to 30 kg with a fine accuracy of 0.1 g. Based on regular use of 8 h a day, five days a week, a single set of batteries will last approx. 5000 h - approx. 2.5 years.

Other features include: selectable weighing; touch-sensitive, capacitive keys covered with hard plastic; auto power-off function; multiple weighing units; and a counting function to calculate and display the number of pieces based on their individual unit weight.
