Hanna HI76409/4 Galvanic Dissolved Oxygen

Hanna HI76409/4 Galvanic Dissolved Oxygen Probe with Built-in Temperature Sensor

The  Hanna HI76409/4 Galvanic Dissolved Oxygen is a high-performance galvanic dissolved oxygen (DO) probe from Hanna Instruments, designed for accurate and stable DO measurement in water and wastewater applications. With a built-in temperature sensor and rugged waterproof construction, it offers reliable results in both laboratory and field conditions.

Key Features

• Built-in Temperature Sensor
  Provides automatic temperature compensation to ensure precise dissolved oxygen readings in varying environmental conditions.

• Durable and Waterproof Construction
  Shielded cable and watertight sealing make it ideal for long-term use in harsh or wet environments.

• Flex-Protect Strain Relief
  Reinforced cable connection with strain relief reduces stress and risk of breakage during repeated use.

• High-Purity Electrodes
  Features a 3.5mm pure silver (Ag⁺) cathode and zinc (Zn) anode for fast response and long-lasting performance.

• Protective Cap
  Protects the probe sensor during storage and transportation.

• Compatible with Standard DO Solutions
  Works with HI-7040L Zero Oxygen Solution and HI-7042S Refilling Electrolyte for accurate calibration and maintenance.
