The VisiTrace mA and RS485 are designed to measure dissolved oxygen in the low ppb range in brewing applications, notably during filtration and filling. Adjacent markets are also boiler feed water in power plant. The VisiTrace offers all the advantages of Hamilton`s optical dissolved oxygen sensors: fast response time and low maintenance. Improvements compared to conventional electrochemical (amperometric) sensors include flow independence, rapid start-up with no polarization time and implified maintenance. Monitoring in low ppb ranges is essential in many applications such as brewing processes and power plants. VisiTrace mA has HART and wireless communication via Bluetooth directly from the sensor to your computer simplifies calibration, configuration, and maintenance. VisiTrace RS485 requires an Arc Wi Adapter for wireless communication.

VisiTrace can also be used in power plants, measurement of dissolved oxygen on boiler plants is essential if the power plant is to be run efficiently and cost effectively with minimum down time. Even small quantities of dissolved oxygen in boiler water will reduce the boiler life dramatically. In boilers where high chloride level exist, the effect of oxygen corrosion is increased. Therefore, the need to monitor dissolved oxygen content down to low ppb levels is even more important. VisiTrace mA has ATEX and IECEx approval.

VisiTrace Sensor Cap

The L1 Cap is optimized for trace measurements from 1 to 2000 PPB (µg/mL) and stable against active chlorine and chlorine dioxide. This cap can be used with VisiTrace mA and VisiTrace RS485.
