Compact bench scales are all-in-one portion control devices with an indicator built right into the scale. Economically priced compact units offer low to mid-range operation for simple weighing needs. Portion control scales are generally smaller, counter top style scales. These scales typically have power provided by both 120 VAC and rechargeable battery. These scales are generally in the wipedown to light washdown category but often do not provide the same "waterproof" ratings as the washdown safe scales which generally are rated at IP69K.
