New Hamilton Company Sensors Enhance Oxygen and Conductivity Measurements for Pharmaceutical and Biotechnology Processing

Published: Aug 31, 2011

Reno, Nevada (August 31, 2011) - Hamilton Company, world leader in fluid measurement, has expanded its ARC sensor line to include two new products for biotech and pharmaceutical processing. The new Oxyferm FDA ARC provides accurate electrochemical oxygen measurements in biotechnology and pharmaceutical fermentation processes, while the new Conducell PWSE ARC provides low conductivity measurements in pure and ultra-pure WFI (water for injection) and CIP (clean in place) validation. The measurement range of the Conducell PWSE is 0.01 to 2,000 ┬ÁS/cm.

Each ARC sensor features a built-in microprocessor that can communicate with both analog (4-20 mA) and digital modbus interfaces. Direct connectivity eliminates the need to send information through costly transmitters and the signals are more robust and reliable than the low currents or voltages produced in classical measurement systems.

The first ARC sensors, introduced last year, revolutionized pH, dissolved oxygen and conductivity measurements. They can be precalibrated and configured right in the lab, reducing costs associated with installation and downtime. On- and offline sensor management delivers extended sensor life and increases process accuracy in challenging production environments. For additional capability, an ARC Wi adapter and the ARC View Handheld unit enable wireless management and calibration of multiple sensors with one device.

"The ARC Sensors save time and money with the elimination of the transmitter, while providing reliable and robust signals with fewer interference issues," explains Amber Ratcliff, product manager for Hamilton. "Customer feedback on the advantages of this technology has been overwhelmingly positive and we are pleased to bring it to an expanding range of applications."

Hamilton Company is a leading worldwide supplier of precision liquid handling equipment, laboratory automation and storage systems, serving customers in academic and private research laboratories, pharmaceutical and clinical diagnostic companies and governmental institutions. Hamilton maintains headquarters in Reno, Nevada and Bonaduz, Switzerland, both of which house R&D and production facilities. Hamilton has subsidiaries for direct sales and service in many countries and works with a wide distributor network in other regions. Hamilton is a privately held company. For more information, visit
