Hanna Optical DO probe with built-in temperature sensor, shield and 20 m cable

The HI764113/20 Optical Dissolved Oxygen (DO) Probe is engineered as a highly durable and user-friendly replacement probe for the HI98198 Optical DO Meter. The advanced design incorporates a built-in thermistor temperature sensor for precise temperature compensation and includes a robust ABS body with a stainless-steel protective guard to ensure reliable operation in challenging environments. The 20 meter cable provides extended reach for use in a wide variety of field, laboratory, and industrial applications.

• This probe offers an IP68-rated enclosure, guaranteeing complete protection from water and dust intrusion during long-term deployments.
• The domed optical cap repels bubbles, delivering high measurement sensitivity and rapid response times.
• No membrane changes or electrolyte replacements are required, minimizing maintenance and user intervention.
• The protective stainless steel guard shields the sensor from impacts and abrasive environments.
• Thermistor-type temperature sensor is integrated for accurate DO readings with temperature compensation.

With an overall body length of 174 mm and a diameter of 25 mm (with guard), it is easy to handle during on-site or in-process measurements. Rated for a maximum operating pressure of 20 meters (29 PSI), this probe meets the needs of professional users across water treatment, aquaculture, environmental monitoring, and research laboratories.

Typical use cases include water quality assessments in rivers, lakes, reservoirs, process control for aquaculture and wastewater, as well as laboratory research work where optical DO sensors are preferred for their accuracy and ease of use.

• Package includes one Optical DO probe HI764113/20 with integrated temperature sensor, stainless steel guard, and 20 m attached cable.
