Hanna HI76401 Dissolved oxygen probe with 4 m

Hanna HI76401 Dissolved Oxygen Probe with 4 m Cable

The Hanna HI76401 Dissolved oxygen probe with 4 m is a compact and reliable dissolved oxygen (DO) probe featuring a 4-meter cable, engineered for accurate oxygen measurements in low-range applications down to parts per billion (ppb). Ideal for environmental monitoring and laboratory testing, this probe utilizes optical measurement principles and EPA-approved methodology for consistent performance.

Features

• High Sensitivity DO Probe: Capable of detecting very low concentrations of dissolved oxygen, ranging from 0 to 200 ppb, with high resolution and reliability.

• EPA Compliant Methodology: Utilizes the Diazotization method (EPA 354.1 adaptation), ensuring compliance for environmental testing.

• Optical Technology: Employs a green LED (525 nm) and a silicon photocell detector for stable and interference-free measurements.

• Automatic Power Saving: Equipped with an auto-off function that activates after two minutes of inactivity to preserve battery life.

• Compact and Portable: Small and lightweight, making it suitable for field measurements or space-constrained laboratory setups.
