Description
The PR140 is a pressure data logger for high temperature applications. Includes ISO17025 accredited calibration certificate
Key Features:
- Submersible
- Accuracy of ±0.03 Bar
- Available in Flush or NPT Pressure Port Top
The PR140 is a pressure data logger designed for use in high temperature applications. This device is completely submersible (IP68) and is available with a 1/8-27 NPT pressure port top, allowing it to connect with a variety of fitting and adapters.
The PR140 can withstand temperatures up to +140 °C (+284 °F) with an accuracy of up to ±0.03 Bar (±0.435 PSI). The PR140 can be programmed to take measurements as often as once per second (1 Hz) and can store up to 32,256 readings.
The PR140 is compatible with the latest MadgeTech 4 Software making starting, stopping, and downloading simple and easy. Graphical, tabular, and summary data is provided for analysis and can be viewed as customizable engineering units.
