Hanna HI76407/4 Dissolved oxygen probe with 4 m

Hanna HI76407/4 Polarographic Dissolved Oxygen Probe with 4 m Cable

The Hanna HI76407/4 Dissolved oxygen probe with 4 m is a standard polarographic dissolved oxygen (DO) probe equipped with a 4-meter shielded, waterproof cable and DIN connection, designed for precise DO measurements with Hanna’s benchtop and portable meters. Featuring a rugged ABS body, integrated temperature sensor, and a replaceable PTFE membrane cap, this probe is ideal for both laboratory and field use.

Features

• Polarographic Sensor: Employs a glass-encapsulated platinum cathode and a silver wire anode to produce a current proportional to the oxygen concentration in solution.

• Integrated Temperature Sensor: Includes a linearized thermistor protected by a stainless steel cover for accurate, temperature-compensated DO measurements.

• Durable Construction: Built with high-strength ABS plastic, suitable for repeated use in the lab or field.

• PTFE Membrane System: Uses screw-cap PTFE membranes (HI76407A/P) to isolate sensor components while allowing oxygen diffusion. Membranes can be quickly replaced and refilled with HI-7041 potassium chloride electrolyte.

• User-Friendly Calibration: Allows quick and simple one- or two-point calibration, ensuring consistent accuracy.

• Cable and Protective Sleeve: Comes with a 4-meter waterproof and shielded cable for stable signal transmission, and a protective sleeve for added durability during use.
