HI-76407/20

The HI-76407/20 is a standard polarographic dissolved oxygen probe with a 20 metre cable for HANNA benchtop and portable dissolved oxygen meters. It contains a platinum cathode and silver anode and is for use with HI-76407A/P PTFE membrane caps. The probe’s tapered design makes it ideal for BOD measurements.

Full Description Specification

The HI-76407/20 is a Polarographic dissolved oxygen probe with internal temperature sensor and a 20m cable.

Hanna Dissolved Oxygen probes are extremely rugged and perfect for laboratory and field applications.

Calibration is fast and simple, and measurements are temperature compensated. The sensitive PTFE (PolyTetraFluoro-Ethylene) membrane can be changed in a few seconds.

The HI-76407/20 is a standard polarographic dissolved oxygen probe for HANNA benchtop and portable dissolved oxygen meters. The probe is made of durable ABS plastic and contains an integrated temperature sensor for temperature compensated measurements. It is compatible with our HI-76407A/P PTFE membrane caps. Each membrane separates the probe’s platinum cathode and silver anode from the water sample being measured. Oxygen diffuses across the membrane and interacts with the polarographic system to produce a current proportional to oxygen concentration. Each cap is easily filled with HI-7041 electrolyte and screwed onto the probe.

Key features:

  • Polarographic Sensor
  • Tapered
  • Shielded, waterproof cable
  • Cable protective sleeve
  • Linearised and accurate thermistor temperature sensor protected behind a stainless steel cover
  • Silver wire anode element
  • Glass encapsulated platinum cathode
  • Screw cap membrane that holds potassium chloride electrolyte solution (HI-7041S)
  • Thin, permeable PTFE membrane isolates the sensor elements from the testing solution, but allows oxygen to enter (Hi-76407A/P)
