The HI98198 Optical Dissolved Oxygen Meter makes measuring the concentration of dissolved oxygen hassle-free. Optical DO technology doesn't require a minimum flow rate, so there is less drift in your readings. Perfect for the field or for the laboratory, the Quick Connect probe requires no membranes, no filling solution, and no warm-up time so you can measure without hesitation. Your meter comes complete in a rugged, custom carrying case for easy transportation.

  • Optical DO technology for fast and stable readings, even in tough environments.
  • Digital probe with Smart Cap Technology eliminates costly, tiresome membranes and solutions.
  • An IP67-rated waterproof, rugged body makes this portable meter ideal for field use.



HI98198 measures dissolved oxygen levels in water using enhanced optical dissolved oxygen technology to ensure high levels of accuracy. With built-in methods and calculations for the measurement of Biological Oxygen Demand (BOD), Oxygen Uptake Rate (OUR), and Specific Oxygen Uptake Rate (SOUR), there is no need for manual conversions.

Increased Traceability

Ensure that your data can be trusted with GLP data. Accessible by a fixed dedicated key, this data includes date, time, pressure, calibrated value, temperature and salinity value of the last calibration.

Versatile Data Logging

The HI98198's log-on-demand feature allows you to store up to 4000 readings. The AutoEnd button can be used during measurement to hold the first stable reading on the display automatically.

Focus on What Matters

When you put on a new cap, your meter will detect and initialize it. It will remind you when your cap needs to be replaced, is damaged, or is missing, giving you one less thing to worry about.




Superior Field Usability

An IP67-rated, waterproof meter means that bad weather, splashes, and dust won't stop you from taking important measurements. The HI98198 is built to withstand immersion in water of 1m for up to 30 minutes. A large display and back light feature ensure that all of your important information is easily visible, no matter the amount of light.

Universal Port

The ultra-versatile USB-C port integrates seamless transfer of data. There is no need for software- simply connect a USB-C and send your data as a .csv to a memory stick, computer, or android device.

Quick Connect Probe

The Quick Connect fitting is designed for quick and easy installation of the DO probe. A watertight connection without threads make attaching and removing the probe simple.




HI764113 Rugged Optical DO Probe for Fresh and Saltwater Applications

Built Strong

A robust ABS body and stainless steel protective guard ensure durability when measuring in tough environments. With an IP68 rating, this probe is totally sealed against water and dust.

Professional Level Performance

The domed cap repels bubbles for better measurement sensitivity, providing a fast response time.

Minimize Hassle

With no additional membranes to change and no electrolyte needed, the opdo probe is ready to work right when you need it.


Smart Cap Technology

Automatic Cap Recognition

Hanna's Smart Caps feature a built-in RFID reader that is able to store important data, including manufacture date and first-use date for increased traceabilty.

Longer Life

Smart Caps last one year from the date of first use. Your meter will automatically count down from initialization and will have your meter remind you when it has expired with an on-screen message.

Aligned Right Every Time

An alignment key ensures that your Smart Cap is on correctly every time.



We believe that buying a meter should be simple. Your Optical Dissolved Oxygen Meter is equipped with everything you need for successful testing right out of the box.

Zero Oxygen Calibration Solution

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


Having the accessories you need on hand makes testing a simple process. The included calibration vessel and beakers fit snug in the rugged carrying case and a USB cable lets you transfer your data with ease.

Complete Package

Your meter, probe, and accessories are all neatly packaged in a rugged carrying case to ensure that you have everything you need for on-the-go field testing.
