Hanna HI76407/20 Dissolved oxygen probe with 20 m

Hanna HI76407/20 Dissolved Oxygen Probe with 20 m Cable

The Hanna HI76407/20 Dissolved oxygen probe with 20 m is a durable, high-performance dissolved oxygen (DO) probe designed for field and industrial applications requiring long cable reach. Featuring a 20-meter shielded, waterproof cable, a protective sleeve, and rugged sensor design, this probe is ideal for monitoring DO levels in lakes, rivers, fish farms, and process tanks.

Features

• Long 20 m Cable: Provides extended reach for deep or remote sampling locations, supported by a shielded and waterproof design to ensure signal integrity.

• PTFE Membrane Technology: The screw-on membrane cap isolates internal sensor elements from the sample while allowing oxygen to diffuse in for accurate measurement. Compatible with HI76407A/P ready-to-use membrane replacements.

• Protective Sleeve: Designed for rugged environments, offering physical protection to the sensor tip during fieldwork or immersion in tanks and basins.

• PEI Body for Field Durability: Constructed from chemically resistant Polyetherimide (PEI), ideal for long-term outdoor or industrial use.

• Integrated Thermistor Temperature Sensor: Delivers linear, accurate temperature readings for reliable temperature compensation; housed behind a stainless steel cover.

• Reliable Electrochemical Design:

  • Cathode: Glass-encapsulated platinum for durability and signal precision

  • Anode: Silver wire for stable electrochemical response

• Easy Maintenance: The screw-cap membrane is filled with HI-7041S potassium chloride electrolyte, easily refillable using various available refill sizes.
