FreshLoc introduces the Differential Pressure Sensor, a sensor for decontamination rooms, cleanrooms, compounding rooms, and any other area in the pharmacy where pressure monitoring is critical. The pressure sensor measures from -500 Pa to +500 Pa and provides uninterrupted monitoring, alerting, and compliance reporting. The sensor integrates with FreshLoc's software platform, which is Web-based, has 83-hour data logging features, and a field changeable battery.
