Backlit graphic LCD display The HI98198 features a backlit graphic LCD with on–screen help and battery life indicator. Dissolved oxygen, barometric pressure, and temperature readings can be displayed in user preferred units. The graphic display allows the use of virtual keys to enhance the intuitive user interface. The meter also displays a text reminder when a scheduled calibration is due. Waterproof protection The meter is enclosed in an IP67 rated waterproof casing and can withstand immersion in water at a depth of 1m for up to 30 minutes.

Connections are facilitated by the Quick Connect 7-pin DIN connector which makes attaching and removing the probe quick and easy. The meter automatically detects the connected probe. Measurement The HI98198 automatically compensates dissolved oxygen concentrations. Temperature and atmospheric pressure compensations are automatically made. Salinity compensation can be manually entered. BOD, OUR and SOUR Dedicated measurement programs are available by using the Mode selection key. Built-in barometer With the internal barometer, the HI98198 is able to compensate for changes in barometric pressure so there is no need for charts, altitude information or external barometric pressure information. Pressure compensation with the meter’s built-in barometer can be validated against a reference barometer, and if needed, can be recalibrated in userselectable units (mmHg, inHg, atm, psi, kPa, mbar). Data logging Log on demand with 4000 records capability. GLP The last ve sets of Calibration data are available by pressing the dedicated GLP key. Calibration values with time and date stamp are captured as well as pressure, salinity and temperature values at the time of calibration. GLP data is available on logged data. Data transfer USB Type-C port for easy data transfer to memory stick, PC, or other compatible devices. Intuitive keypad The tted rubber keypad has dedicated keys for power, backlight, up/down arrows and help. The meter also features two virtual soft keys that navigate the user through the conguration, meter setup, and logging of data. The interface is intuitive for any user’s level of experience.
