DESCRIPTION

Compact and easy to use:

HI6421 incorporates Hanna's HI7641133 optical dissolved oxygen (opdo) probe based on the fluorescence quenching principle. An immobilized Pt-based phosphor is excited by light from a blue LED and emits red light. As oxygen interacts with the phosphor, it reduces the intensity and lifetime of the luminescence. The luminescence lifetime is measured by a photodetector and is used to calculate the dissolved oxygen concentration.®

7-inch capacitive touchscreen with multi-touch support
Capacitive touch feedback, home and system menu keys
User-friendly icons and symbols allow users to easily navigate and interpret the instrument's functions.

Calibration:

One or two calibration points at 0% and/or 100% saturation. Manual one-time calibration in mg/L or % saturation using a reference method. Non-volatile memory stores data and settings

Zero Oxygen Calibration Solution:

When performing a DO calibration, it is important that the correct standards are used. We include a starter solution to help you get started. HI7040L is a two-component, zero-oxygen solution designed so you can quickly calibrate to 0% oxygen concentration.

Connectivity Features and Services:

Transfer the saved data to a USB flash drive
Log files containing measurements and calibration data (as a .csv file)
FTP and email for exporting logs via Ethernet and Wi-Fi connection
USB type A for USB flash drive, keyboard and printer / USB type C for USB flash drive and PC connection
