Palintest Inc., has developed a new meter for the accurate testing of molybdate formulations. Used as corrosion inhibitors in industrial water treatment, the Molybdate Duo Meter tests high concentration levels as well as trace amounts, an increasingly important test for effluents and industrial discharges. Molybdate-based formulations are frequently used in cooling systems, closed recirculating systems such as water heating systems, and chilled water systems. Low levels of molybdate are also mixed in with other boiler and cooling water products for the determination of levels in a system. For example, a 1.5 to 2.0 ppm level may indicate 100 ppm of product.
