The HI98198 portable dissolved oxygen meter delivers enhanced optical DO measurement technology for precise environmental, industrial, and wastewater monitoring.
Designed to streamline your testing process, the HI98198 automatically calculates Biological Oxygen Demand (BOD), Oxygen Uptake Rate (OUR), and Specific Oxygen Uptake Rate (SOUR) without requiring manual conversions, saving time and minimizing errors.
Access complete GLP (Good Laboratory Practice) data at the press of a button, including the last calibration time, date, pressure, temperature, salinity, and calibration values, ensuring full accountability for every reading.
The HI98198 offers flexible log-on-demand functionality, allowing you to store up to 4,000 data points. Utilize the AutoEnd feature to automatically capture stable readings for consistent and reliable documentation.
The optical DO sensor automatically detects when a new cap is installed and will notify you when replacement, damage, or missing cap issues arise — reducing maintenance guesswork and improving system uptime.
The HI98198 portable dissolved oxygen meter is IP67-rated, providing complete protection against water, dust, and harsh outdoor environments. Built to withstand submersion up to 1 meter for 30 minutes, it ensures reliable performance even in challenging field conditions. A large, easy-to-read backlit display makes critical data visible in any lighting situation.
With an integrated USB-C port, exporting data from the HI98198 is effortless. No special software is needed—just connect a USB-C cable to a flash drive, PC, or Android device and save measurement results directly as .csv files for easy reporting and analysis.
The Quick Connect fitting allows for fast, secure probe attachment without the need for threading or complicated fittings. A watertight design ensures that field installation and removal of the DO sensor are simple, efficient, and hassle-free.
Designed for both freshwater and saltwater environments, the HI764113 optical dissolved oxygen probe offers outstanding durability and fast, accurate measurements, even in demanding field conditions.
An impact-resistant ABS plastic body combined with a stainless steel protective guard shields the sensor from physical damage. Rated IP68, the probe is fully sealed against dust and water intrusion for reliable operation during long-term deployments.
A domed optical cap minimizes bubble interference, enhancing sensitivity and delivering faster, more accurate dissolved oxygen readings.
The HI764113 probe eliminates the need for membrane replacements and electrolyte refills, streamlining maintenance and allowing you to focus on your measurements with minimal downtime.
The HI98198 features innovative Smart Cap technology, incorporating a built-in RFID chip to enhance traceability and streamline cap management.
Each Smart Cap stores key information such as manufacturing and first-use dates. The HI98198 automatically recognizes the installed cap, ensuring traceable calibration and simplified maintenance tracking.
Smart Caps are designed for optimal performance with a one-year lifespan from the first initialization. The meter automatically tracks cap usage and alerts you when replacement is due—helping you maintain accuracy without guesswork.
A precision alignment key ensures that Smart Caps are securely and correctly positioned, eliminating installation errors and maximizing sensor performance.
The HI98198 optical dissolved oxygen meter comes complete with all essential tools, allowing you to start testing right out of the box—no hidden extras required.
Proper calibration is key to achieving accurate dissolved oxygen measurements. To help you get started, the HI98198 includes HI7040L bi-component zero oxygen calibration solution, making it easy to calibrate your meter to 0% oxygen concentration.
A rugged calibration vessel, beakers, and a USB cable are all neatly organized in the carrying case, giving you the tools you need for fast calibration, reliable testing, and easy data transfer whenever needed.
Your HI98198 meter, optical DO probe, calibration materials, and accessories are securely packed into a durable, field-ready case designed to withstand the demands of environmental and industrial testing applications.
