The PR140 is a pressure data logger designed for use in autoclave validation and mapping. This rugged data logger can withstand temperatures up to +140 °C (+284 °F) and is completely submersible (IP68). The PR140 is built with a precision stainless steel pressure gauge. The data logger has an accuracy of ±0.03 Bar (±0.435 PSI), which can be achieved over a wide temperature range, from +20 °C to +140 °C (+68 °F to +284 °F). The PR140 can be programmed to take readings as often as once per second (1 Hz), and has non-volatile memory that can store up to 32,700 measurements.
The PR140 data logger is easy to use. Simply place it in the IFC400 docking station, connect to a computer, and the device can be started, stopped or downloaded using the MadgeTech software. Graphical, tabular and summary data is provided for analysis and can be viewed in PSIA, mmHg, bar, Torr and kPa. The data can also be automatically exported to Excel® for further calculations.
