RENO, Nev., (April 20, 2010) -- Hamilton Company, world leader in fluid measurement, introduces the pHeasy Arc Sensor, an advanced-technology tool for accurate process pH measurement without recalibration. The pHeasy Arc sensor incorporates a unique ChekRef device that provides feedback on the accuracy of the pH measurement, delivers an alert when an electrode needs replacement, monitors chloride loss and detects reference poisons. Users can set inaccuracy limits for warnings and alarms based on the status of the sensor quality including glass resistance, reference resistance, and the CheckRef potential. As part of the new Arc Sensor family, pHeasy also features direct communication with the process logic controller (PLC) without transmitters, enabling fast delivery of the feedback measurements for timely adjustments through a 4-20 mA or digital signal.
With pHeasy Arc Sensors, one calibration at the start of the operation is sufficient; time-consuming recalibration is eliminated. The ongoing accuracy monitoring extends service intervals and increases the reliability of pH measurement.
“The pHeasy Arc sensors incorporate two unique technologies that deliver a quantum leap in sensor performance,” commented Amber Ratcliff, product manager for Hamilton. “The Arc digital connection improves data integrity, productivity and product life.”
