Hanna HI76407/20F DO probe with protective sheath 20 m

Hanna HI76407/20F Dissolved Oxygen Probe with Protective Sheath and 20 m Cable

The Hanna HI76407/20F DO probe with protective sheath 20 m is a high-performance polarographic a protective sheath, and a robust sensor assembly. Designed for long-term deployment in natural water bodies or process tanks, it delivers precise and stable DO readings under challenging environmental conditions.

Features

• Long 20 m Shielded Cable: Waterproof and shielded to ensure accurate signal transmission, even during long-distance measurements in demanding environments.

• PEI Body with Protective Sheath: Constructed from Polyetherimide (PEI) for superior mechanical and chemical resistance, and includes a sleeve to protect the sensor during immersion in turbulent or debris-laden waters.

• Reliable Sensor Design:

  • Cathode: Glass-encapsulated platinum

  • Anode: Silver wire element

• Integrated Thermistor Sensor: Ensures precise temperature compensation, housed behind a stainless steel protective cover for long-lasting performance.

• Screw Cap Membrane System: Holds HI-7041S potassium chloride (KCl) electrolyte and is easily replaceable in the field, supporting low-maintenance operation.

• PTFE Membrane: A thin, gas-permeable membrane that separates the sensor elements from the water while allowing oxygen to diffuse in for measurement. Compatible with HI-76407A/P membrane caps.

• Solution Cycling Port: Designed with a flow-through opening that enhances solution exchange at the membrane surface for faster response and improved accuracy.
