The Molybdate Duo Meter provides a single meter capable of measuring tracer levels of Molybdate as low as 0.10ppm, with a range of 0.0 to 20.0 ppm and a high range for measuring levels of 0 to 100 ppm as MoO4.

Formulations containing Sodium Molybdate are used as corrosion inhibitors in industrial water treatment. In particular, Molybdate finds application in cooling towers and in closed recirculating systems such as hot water heating and chilled water systems. Molybdates have replaced toxic corrosion inhibitors such as Chromates.

When using Molybdate treatment, it is necessary to control the Molybdate concentration within specified levels depending on the application involved. Molybdates are used extensively for corrosion inhibition and also as a tracer reagent in many boiler and cooling water products. Low levels of Molybdate are mixed in with the products for the determination of product levels in a system i.e. a 1.5 to 2.0 ppm level may indicate 100 ppm of product.

The Molybdate-Duo meter is suitable for bench use in laboratories or for field use by sampling engineers or contractors. The instrument is supplied in a soft carry pouch with a belt loop for maximum portability, or with an optional hard carry case for added convenience. The kit comes complete with test tubes, reagents and full operating instructions. It is also supplied with a test certificate confirming conformance to calibration standards. Certified check standards are available as an optional extra.
