2. GENERAL DESCRIPTION & INTENDED USE
HI98494 is a portable logging multiparameter system (meter and probe) that monitors up to 13
different water quality parameters (6 measured and 7 calculated) such as pH, ORP, conductivity,
dissolved oxygen and temperature. The HI98494 features a graphic, backlit display that automatically
sizes the digits to fit the screen with on-screen graphing capability. Each parameter is fully configurable.
The HI7698494 microprocessor-based intelligent multisensor probe uses a HI7698194-1 sensor for
pH and ORP measurements, the HI7698194-3 sensor for conductivity and associated parameters,
and a HI7698494-5 Optical DO sensor with HI764113-1 DO Smart Cap for measurements of
dissolved oxygen. The Optical DO sensor provides accurate DO measurements over long periods of
time without the need for frequent calibration. The probe also has a built in temperature sensor and
a removable protective shield.
The HI98494 system is easy to setup and use. It has a built-in tutorial mode to guide users step-by-
step through sensor preparation, installation, maintenance and calibration processes.
The meter utilizes a dual charging system, utilizing a rechargeable Li battery and backup alkaline
batteries to extend field use.
The meter can log data that can be easily downloaded as a CSV file or graph using Bluetooth
®
wireless technology to Hanna Lab on iOS and Android devices or to a PC using a USB type A to C cable.
The HI98494 meter was designed to withstand harsh environmental conditions and is ideal for field
measurements. The meter meets IP67 standard (30 minute immersion at a depth of 1 m) and the
multi-sensor probe is totally sealed against water and dust, and meets IP68 standard (continuous
immersion in water).
