HI-76407/20F Dissolved Oxygen Probe with Protective Sleeve, 20m Cable
HI-76407/20F
The HI-76407/20F is a Polarographic dissolved oxygen probe with internal temperature sensor and a 20m cable. The probe has a protective sleeve making it ideal for use in rugged or demanding environments.
The HI-76407/20F 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:
- Shielded, waterproof cable
- Cable protective sleeve
- PEI probe for best field protection
- 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)
- Hole for solution cycling
- Protective sleeve for field applications
This probe is supplied complete with a 20m cable and DIN connector
Calibration is fast and simple, and measurements are temperature compensated. The sensitive PTFE (PolyTetraFluoro-Ethylene) membrane can be changed in a few seconds.
