The Model 4020™ Drum Scale is specially designed for weighing corrosive materials. The drum can be placed anywhere on the platform and still be weighed accurately. The low profile (1.5") provides added safety and ease of drum handling. Loading and unloading drums can be accomplished by rolling and tilting onto the scale or by using a hand truck. The 12" diameter scale can be used to weigh liquified chlorine, sulfur dioxide, ammonia, hydrogen chloride, or carbon dioxide packaged in carboys. The 16" diameter scale can also be used to weigh ammonia cylinders as well as drums and daytanks. The base is solid PVC with a dry powder polyester plastic coated steel plate under the disk on the 16" scale. All hardware is stainless steel.

Three indicators are available for this scale; all are mounted in NEMA 4x, UL approved enclosures. The standard indicator is a 3½ digit liquid crystal display, LCD, with 4-20mA output. This display can read up to 199.9 lbs. or kgs. When substance to be weighed is between 200 and 1000 lbs., this indicator is calibrated to display in 1 lb. ( or kg.) increments. The optional indicator with 4½ digit LED display can display 1000.0 lbs. by one tenth of a pound increments. It has both active and passive 4-20 mA output. There are two adjustable low level set points. The Model 1099™ Chemical Process Controller is also available on this base, which allows the user to combine different bases to create a customized Total Electronic System^SM. Please contact the factory for literature on the Model 1099™ Chemical Process Controller.

All of our indicators can be calibrated in pounds or kilograms.
