Hanna HI764113 Optical DO probe

Hanna HI764113 Optical Dissolved Oxygen Probe with Built-in Temperature Sensor and 4 m Cable

The Hanna HI764113 Optical DO probe is a high-precision optical dissolved oxygen (DO) probe designed for fast, stable, and maintenance-free DO measurements in a wide range of applications. Utilizing advanced luminescence quenching technology, this probe eliminates the need for frequent calibration, membranes, or electrolyte solutions. It features a built-in thermistor for accurate temperature compensation and comes with a rugged 4-meter (13’4″) cable for reliable use in the field or laboratory.

Key Features

• Optical DO Measurement (Luminescence Quenching)
  Provides fast and accurate readings with minimal drift, no oxygen consumption, and no need for electrolyte refilling or membrane replacement.

• Built-in Temperature Sensor
  Equipped with a thermistor that delivers real-time temperature compensation, ensuring highly accurate DO readings.

• IP68-Rated Waterproof Design
  Fully submersible with an ingress protection rating of IP68, suitable for continuous operation in harsh or submerged environments.

• Robust and Durable Materials
  The probe body is constructed from durable ABS plastic, while the sensor is protected by a stainless steel (316) guard, enhancing mechanical strength and resistance to corrosion.

• Smart Cap System
  The optical sensor cap, made from polypropylene, is factory-calibrated and stores sensor data for true “plug and play” performance.

• Long Cable for Field Use
  Includes a 4-meter (13.4 ft) shielded cable with PVC jacket, ideal for on-site water testing in rivers, lakes, tanks, and treatment systems.
