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.
The 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.
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.
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.
