HI-6421 Advanced Dissolved Oxygen Optical Benchtop Meter
HI-6421 Advanced Dissolved Oxygen Optical Benchtop Meter
HI-6421 Advanced Dissolved Oxygen Optical Benchtop Meter
Supplied by GAPS Water Treatment, the HI-6421 Advanced Dissolved Oxygen (DO) Optical Benchtop Meter is the pinnacle of precision and functionality for laboratory-grade water analysis. Designed for measuring dissolved oxygen, oxygen uptake rate (OUR), specific oxygen uptake rate (SOUR), and biochemical oxygen demand (BOD) in both freshwater and saltwater, this benchtop meter offers unparalleled accuracy, reliability, and ease of use.
A Precision Tool for the Modern Laboratory
Supplied with the HI-7641133 Opdo optical dissolved oxygen probe, the HI-6421 ensures consistently accurate measurements. The included Smart Caps (HI-764113-1) are pre-loaded with calibration coefficients, allowing seamless and precise auto-calibration. Using advanced fluorescence quenching technology, this DO meter delivers exact DO measurements over extended durations without frequent recalibration, saving time and effort.
Space-Saving Design for Ultimate Convenience
The HI-6421 is engineered with modern laboratories in mind. Its compact footprint and capacitive touchscreen—operable even with gloves—make this meter as versatile as it is functional. Place it anywhere in your lab with its flexible electrode holder, which can be mounted on either side of the unit for maximum convenience.
Connectivity and Data Management Made Easy
WiFi and Ethernet integration give you the freedom to position the meter wherever it’s most convenient. Effortlessly transfer data remotely via email or FTP, or export up to one million data points directly using WiFi, Ethernet, or USB. Comprehensive storage ensures detailed time and date stamps for every record, making it easier than ever to keep organized and compliant with laboratory data standards.
Intuitive Interface, Exceptional Usability
With its user-friendly interface, the HI-6421 delivers a simple and efficient user experience. Choose from five display options—Basic, Simple GLP, Full GLP, Graph, or Tabulated View—each tailored to specific monitoring and research needs. The integrated video and text tutorial system guarantees smooth operation right out of the box, while customizable user accounts ensure tailored access for laboratory staff.
Stay Alert with Dual Alarms
The configurable dual alarm system, featuring both audible and visual cues, guarantees you’ll never miss critical measurements. Set precise ranges that suit your samples and immediately identify deviations for fast response and quality control.
