Endress Hauser Digital oxygen sensor Memosens COL37E

The Memosens COL37E is a digital optical oxygen sensor from Endress+Hauser, designed for laboratory analysis and random sampling in the field. Featuring Memosens 2.0 technology and a fast-responding optical measuring principle, it enables quick and reliable checks of oxygen levels in aeration tanks, fish farms, and surface water.

Key Features and Benefits

  • Optical Measuring Principle: The sensor uses luminescence-based optical oxygen measurement, requiring no electrolyte and no polarization time, making it simple to operate and maintain.

  • Flow-Free C-Shaped Optical Cap: The C-shaped cap design eliminates interference from air bubbles, ensuring stable and accurate measurements even in demanding conditions.

  • Fast Response Time: With a response time (t90) of less than 20 seconds from air to nitrogen, the sensor delivers rapid measurement results.

  • True Plug-and-Play with Memosens 2.0: Simply connect the sensor and measurements can begin immediately. Measured values, calibration data, and sensor history are stored directly in the sensor head, enabling status checks and supporting GLP requirements.

  • Inductive Coupling: The inductive Memosens coupling between the sensor and the mobile CML18 handheld device is insensitive to moisture and corrosion, ensuring secure data transmission in demanding environments.

  • Integrated Temperature Sensor: A built-in Pt1000 temperature sensor enables automatic temperature compensation and registration for accurate oxygen readings.

  • Traceable Calibration History: The sensor features tamper-proof data storage including serial number and calibration history, supporting quality management requirements.

The Memosens COL37E is a digital optical oxygen sensor from Endress+Hauser, designed for laboratory analysis and random sampling in the field. Featuring Memosens 2.0 technology and a fast-responding optical measuring principle, it enables quick and reliable checks of oxygen levels in aeration tanks, fish farms, and surface water.

The sensor operates on the optical (luminescence-based) measuring principle, requiring no electrolyte and no polarization time, making it simple to operate and maintain. Its flow-free C-shaped optical cap design eliminates interference from air bubbles, ensuring stable and accurate measurements even in demanding conditions. The sensor delivers a response time (t90) of less than 20 seconds from air to nitrogen, providing rapid measurement results. The measuring range covers 0 to 330 %SAT (0 to 20 mg/l).

The Memosens 2.0 digital technology provides true plug-and-play capability. Simply connect the sensor and measurements can begin immediately. Measured values, calibration data, and sensor history are stored directly in the sensor head, enabling status checks and supporting GLP requirements. The inductive Memosens coupling between the sensor and the mobile CML18 handheld device is insensitive to moisture and corrosion, ensuring secure data transmission in demanding environments. All sensors are supplied pre-calibrated and are directly ready for use.

The sensor features a built-in Pt1000 temperature sensor for automatic temperature compensation and registration, ensuring accurate oxygen readings. The tamper-proof data storage unit includes serial number and calibration history information, supporting quality management requirements and traceable sensor calibration.

The COL37E is suitable for a variety of applications including surface water, wastewater, and process water monitoring. It can be used for online checks of measuring loops, sample analysis in both laboratory and field settings, and measurements at process points requiring regular inspection. The sensor has a diameter of 12 mm (0.47 inch) and shaft length of 120 mm (4.72 inch), with IP68 ingress protection. The process temperature range is –5 to +60°C (23 to 140°F) at 1 bar pressure, and it is not intended for continuous measurement in process. The sensor body is constructed of stainless steel.
