Hanna HI76407/4F DO probe with protective sheath 4 m

Hanna HI76407/4F Dissolved Oxygen Probe with Protective Sheath and 4 m Cable

The Hanna HI76407/4F DO probe with protective sheath 4 m is a robust and field-ready polarographic dissolved oxygen (DO) probe designed for accurate oxygen monitoring in demanding environments. With a 4-meter shielded, waterproof cable, integrated temperature sensor, and a protective sheath, this probe is ideal for field researchers, aquaculture technicians, and water quality professionals.

Features

• Compact and Rugged for Field Use: Built for portability and reliability, the 4-meter cable length allows convenient sampling in small tanks, shallow water bodies, or laboratory setups.

• PEI Probe Body with Protective Sleeve: Constructed from Polyetherimide (PEI) for superior resistance to impact and chemicals. The protective sheath guards the sensor tip during immersion and handling in rough environments.

• Advanced Sensor Components:

  • Cathode: Glass-encapsulated platinum

  • Anode: Silver wire element

• Integrated Thermistor Sensor: Ensures precise temperature-compensated readings, protected by a stainless steel housing.

• Reliable PTFE Membrane System: Thin, gas-permeable PTFE membrane allows oxygen to diffuse into the sensor while keeping out contaminants. Compatible with HI76407A/P screw-cap replacement membranes.

• Quick Maintenance and Calibration:

  • Easy membrane replacement

  • Supports HI-7041S potassium chloride electrolyte solution

  • Compatible with HI-7040L zero oxygen solution for 0% calibration

• Hole for Solution Cycling: Enhances water flow at the sensor tip for improved response time and stable readings.
