These new spill-containment scales weigh only the chemical dispensed into the water treatment system and are not affected by chemical spills. The scales have four load cells that are completely sealed in PVC and vinyl plastic enclosures to protect from spilled chemicals. The scale platforms are resistant to most water treatment chemicals such as: fluoride, sodium hypochlorite, sodium hydroxide, sodium bisulfate, polymers, ammonia, phosphate, alum, caustic, sodium aluminate or other liquids or powders. The chemical containers do not have to be centered, balanced or leveled. The scales have a low-profile design, with a frame height that does not exceed 1.5 in., facilitating easy on and off loading of heavy containers. The Model 4042 spill-containment scale contains moderate spills, while the Model 4042WB has the additional benefit of a special rollout bladder to hold the contents of the container being weighed if spilled or leaked. — Scaletron Industries, Ltd., Plumsteadville, Pa.
