COA30 flow assembly for calibrating dissolved oxygen sensors with a length of 120...360 mm and a diameter of 12 mm
Advantages
• Precise calibration of dissolved oxygen sensors using test gas: the COA30 calibration vessel enables precise calibration of dissolved oxygen sensors to match the requirements of the relevant measuring point exactly.
• Easy calibration of dissolved oxygen sensors: install the sensor in the calibration vessel, connect the corresponding transmitter and supply a suitable test gas to complete the calibration easily.
• Saves time on zero-point calibration: calibration with the COA30 calibration vessel is significantly faster than conventional calibration methods using sodium sulfite or zero-point gel.
• After calibration with the COA30, no residue remains on the sensor, so cleaning is not required. Calibration with a test gas (e.g. nitrogen) eliminates subsequent cleaning work.
• Compatible with sensors of various sizes: the calibration vessel is suitable for 12 mm dissolved oxygen sensors with PG13.5 thread connection and lengths from 120 mm...360 mm, offering a wide range of applications.
Field of application
The Flowfit COA30 is an efficient tool for calibrating oxygen sensors. The sensor can be installed quickly and easily in the flow assembly and calibrated with a test gas —— precisely tailored to your specific measuring requirements.
