Hanna HI98198 Optical Dissolved Oxygen Meter

Description

The Ultimate Tool for Oxygen Measurement

The Hanna HI98198 Optical Dissolved Oxygen Meter is a professional-grade, rugged, and portable device designed for a wide range of dissolved oxygen measurements in both fresh and saltwater environments. This sophisticated meter, compliant with IP67 standards, is not just for DO; it also measures barometric pressure and temperature automatically, ensuring high accuracy in all conditions. The HI98198 simplifies the process of measuring DO concentration with its advanced optical technology, which eliminates the need for a minimum flow rate, a common requirement for traditional meters that can cause reading drift.

This means you get fast, stable readings even in demanding conditions. Unlike older models, the Quick Connect probe does away with the hassle of membranes, filling solutions, and long warm-up times, allowing for immediate and effortless measurements. The entire system is housed in a durable, custom-designed carrying case, making it an ideal companion for field professionals who need reliability and convenience on the go. The meter’s ergonomic design provides ready access to all the necessary materials for routine sampling, enhancing its practicality. This is a tool built for professionals who value precision, durability, and ease of use in one compact package.

Harnessing Optical Dissolved Oxygen Technology

At the heart of the Hanna HI98198’s superior performance lies its innovative optical DO technology. This method operates on the principle of fluorescence quenching. A platinum-based luminophore is excited by a blue LED, causing it to emit a red light. When dissolved oxygen is present, it interacts with this luminophore and quenches the excitation, which shortens the lifetime and reduces the intensity of the luminescence. A photodetector then precisely measures this lifetime, and the meter uses this data to calculate the dissolved oxygen concentration.

This sophisticated process is automatically compensated for temperature, barometric pressure, and salinity, ensuring highly accurate results without the need for manual conversions. The design of the probe, with its Smart Cap™ technology, further enhances performance by including a built-in RFID reader that stores crucial data like the manufacture and first-use dates. The optical sensor’s components are designed to compensate for aging over time, providing accurate measurements for extended periods without frequent calibration. This technology is a significant advancement over traditional methods, providing a reliable and low-maintenance solution for dissolved oxygen measurement. The convenience and accuracy it offers make it an invaluable asset for environmental scientists, water quality technicians, and anyone requiring precise DO readings.

Specialized Functions for Field Scientists

The Hanna HI98198 is more than just a simple DO meter; it is a versatile instrument with built-in functionalities tailored for specific scientific applications. It features dedicated modes and calculations for Biochemical Oxygen Demand (BOD), Oxygen Uptake Rate (OUR), and Specific Oxygen Uptake Rate (SOUR). This capability eliminates the need for cumbersome manual conversions and complex calculations, streamlining the analysis process for professionals. These built-in programs are easily accessible via the Mode selection key. For environmental scientists and lab technicians who frequently conduct these tests, this feature is a game-changer. It ensures that crucial data is generated quickly and accurately, allowing for more efficient fieldwork and lab operations. The meter’s built-in barometer is another key feature, automatically compensating for changes in atmospheric pressure. This eliminates the need for external charts or altitude information, which can be prone to error. The pressure compensation can even be validated and recalibrated against a reference barometer in user-selectable units, providing an extra layer of confidence in the data. This comprehensive set of specialized features cements the HI98198’s position as a professional, all-in-one solution for advanced dissolved oxygen analysis.

Unmatched Durability and Usability

The Hanna HI98198 is engineered for superior field usability and durability. Its IP67-rated waterproof and rugged enclosure is built to withstand harsh conditions, making it resistant to dust and capable of immersion in water up to 1 meter deep for 30 minutes. This robust design ensures that important measurements can be taken regardless of bad weather, splashes, or accidental drops. The meter features a clear, backlit dot-matrix display with multi-function virtual keys, ensuring all readings and information are easily visible even in low-light conditions. The intuitive interface, designed for users of all experience levels, is enhanced by a dedicated HELP key that provides context-specific assistance at any time. The keypad, with its fitted rubber finish, includes dedicated keys for power, backlight, navigation, and help, making operation simple and direct. The meter’s AutoEnd feature further simplifies operation by automatically freezing the first stable reading on the display with a single button press. These features, combined with the device’s light weight of only 450 grams, make it the perfect portable tool for extensive field use.

Comprehensive Data Management and Traceability

Data management and traceability are critical for professional applications, and the Hanna HI98198 excels in this regard. The meter offers a flexible data logging feature with the capacity to store up to 4000 records on demand. Additionally, it supports interval logging with a storage capacity of up to 10,000 records in up to 100 files, offering immense versatility for long-term monitoring projects. Data can be seamlessly transferred using the versatile USB Type-C port to a memory stick, PC, or other compatible device. This universal port eliminates the need for specialized software; data is simply transferred as a standard .csv file. To ensure data integrity, the meter includes a dedicated GLP (Good Laboratory Practice) key that provides access to the last five calibration records, including the date, time, calibration points, barometric pressure, temperature, and salinity settings. This high level of traceability ensures that all data can be trusted and is essential for compliance and quality control in scientific and industrial settings.

Seamless Operation and Smart Technology

The Hanna HI98198 is engineered for seamless and hassle-free operation from the moment you start using it. The Quick Connect 7-pin DIN connector facilitates the easy and quick attachment and removal of the HI764113 optical DO probe, ensuring a watertight connection without cumbersome threads. The meter automatically detects the connected probe, simplifying setup. The Smart Cap™ technology further enhances user experience. The meter automatically recognizes a new cap and will remind you when it’s time for a replacement, if it’s damaged, or if it’s missing. This proactive feature helps prevent measurement errors and ensures that the device is always performing at its best. The cap itself is designed for a one-year lifespan from the date of first use, and the meter’s countdown feature provides a clear on-screen reminder when it’s nearing expiration. The integrated alignment key guarantees that the cap is always correctly positioned, eliminating another potential source of error. This combination of smart design, automated features, and robust build quality makes the HI98198 exceptionally user-friendly and reliable.
