What is MBT:
MBT is formulated with various water treatment products to prevent corrosion of copper and copper-containing metals. These tests are well-suited to the monitoring of closed-loop cooling water systems and utility condensers where high MBT concentrations are usually maintained. MBT is very toxic to aquatic life and leaves long-lasting damage to it.
MBT Exposure and Health Risks:
MBT is a chemical allergen, causing a reaction of increased histamine release and cell-mediated immunity, as well as skin reactions. It is very irritating to eyes and skin. MBT is also a probable carcinogen and is harmful by inhalation, ingestion, and absorption. When heated to decomposition, the fumes it emits are highly toxic.
Regulations:
There are no listed regulations or restrictions for levels of MBT in water.
Measuring MBT:
Dissolved MBT concentration in water can be measured in units of parts per million (ppm). We carry a kit from CHEMetrics that determines MBT levels in water, ranging from 50-500 ppm. Our MBT products can be viewed HERE.
All sensors require a yearly calibration to ensure your gas measurements are accurate and performing within manufacturer standards. This page is desiccated to the individual manufacturers we represent and their specific calibration procedures.Â
