Online ConsultationProduct Introduction
The online bromine analyzer is an instrument designed for real-time monitoring of bromide ion levels. Based on national standards, the instrument features simple operation, high automation, ease of maintenance, and low consumable costs. It is equipped with RS485/RS232 interfaces and supports the MODBUS protocol, enabling comprehensive monitoring of its operational status and data via remote communication, as well as remote control functions such as remote analysis, calibration, and cleaning. The instrument has built-in dilution functionality, making it suitable for high-concentration samples. It is applicable for: wastewater, sewage, etc.
The method is based on the determination of bromide using the bromophenol red spectrophotometric method (DZ/T0064.46). At pH = 4. 7 to 5.0, chloramine T oxidizes bromide ions in water into bromine, which reacts with phenol red to form a purple tetrabromophenol red complex. The intensity of the complex's color increases with bromine concentration, allowing the concentration of bromide ions in water to be calculated based on the absorbance value.
