New optical dissolved oxygen sensor for craft brewers launched by Hamilton Co.

Hamilton Co. introduced the VisiTrace Optical DO Sensor, which provides trace, low-ppb dissolved oxygen measurement in the beer-making processes. The sensor’s unique design integrates the transmitter, eliminating the costs associated with buying and installing a separate transmitter. According to the company, VisiTrace has the smallest footprint of all DO sensors and it can be configured and calibrated from a smartphone via Bluetooth.

“Mid-sized and smaller breweries can now afford to maximize shelf life with a sophisticated dissolved oxygen sensor,” commented Don Spriggs, sensors market segment manager for Hamilton. “With a unique design that includes eliminating the separate transmitter, we’ve been able to engineer this product to meet the craft brewing industry’s needs.”

VisiTrace delivers accurate and undistorted measurements across all conditions and concentrations and is not affected by flow or CO2, the company stated. The sensor’s optical sensor cap is resistant to cleaning solutions such as active chlorine and chlorine dioxide, and the robust sensor does not need calibrating after each clean-in-place (CIP) cycle. VisiTrace measures very low – 0 to 2,000 ppb – levels, does not require polarization and has virtually no maintenance requirements. An easy exchange of the sensor cap is all that is occasionally required.
