The Hanna Instruments-76407/10F is a Polarographic dissolved oxygen probe with internal temperature sensor and a 10m cable.
Calibration is fast and simple, and measurements are temperature compensated. The sensitive PTFE (PolyTetraFluoro-Ethylene) membrane can be changed in a few seconds.
Hanna Dissolved Oxygen probes are extremely rugged and perfect for laboratory and field applications.
The probe is made of durable ABS plastic and contains an integrated temperature sensor for temperature compensated measurements. It is compatible with our Hanna Instruments-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 Hanna Instruments-7041 electrolyte and screwed onto the probe.
