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.

Increased Traceabilty

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 initialise 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.
