The Model 4021™ Ultra Low Profile Carboy / Drum Scale is specially designed for weighing corrosive materials. The base has rugged polyester dry powder coated steel frame for on and off loading of carboys and drums. All steel parts are coated with a corrosion resistant finish. Hardware is stainless steel. The PVC decking provides a buffer between the steel frame and drums to protect the frame from scratches. A rugged steel backstop helps to align the centering mark for the drum. The platform of the Model 4021™-18 can handle drums from 10 inches to 18 inches and the Model 4021™-26 can accommodate drums from 18 inches to 26 inches in diameter by adjusting the heavy duty backstop. For operation, the scale employs a NTEP stainless steel temperature compensated strain gauge transducer. It offers high accuracy of ±0.5% of capacity.

Three indicators are available for the Model 4021™ Ultra Low Profile Drum Scale. All are mounted in a NEMA 4x, UL approved enclosures. The standard indicator is the 3 1/2 Digit with liquid crystal display(LCD), and standard 4-20 mA output. Display reads either 0.1 lb./kg. to 199.9 lbs./kg., or 1.0 lb./kg. to 1500 lbs./680 kg. Optional indicators include the 4 1/2 Digit, LED indicator with standard active and passive 4 -20 mA output and two low level relay contacts. This display has a resolution of 1500 lbs.(680 kg.)

The Model 1099™ Chemical Process Controller is also available on this base, which allows for 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.
