Chapter 1 - INTRODUCTION
1.1 PRELIMINARY EXAMINATION
Remove the instrument from the packing material and examine it carefully to
make sure that no damage has occurred during shipping. If there is any damage,
notify your Dealer or the nearest HANNA Customer Service Center immediately.
Note Save all packing materials until you are sure that the instrument
functions correctly. Any damaged or defective items must be returned
in their original packing material with the supplied accessories.
1.2 MODEL IDENTIFICATION
HI 98194 pH/EC/DO Multiparameter meter with HI 7698194 probe.

1.3 GENERAL DESCRIPTION
HI 9819X is a portable logging multiparameter system (instrument, probe) that
monitors up to 14 different water quality parameters (7 measured, 7 calculated).
The microprocessor-based intelligent multisensor probes allows measurement of
many water quality parameters such as pH, ORP, dissolved oxygen, conductivity
and temperature with data logging. The system is easy to setup and easy to use.
The HI 9819X features a graphic, backlit display that automatically sizes the
digits to fit the screen with on-screen graphing capability. Each parameter is fully
configurable.
HI 9819X was designed to withstand harsh environments and is the ideal solution
for field measurements of lakes, rivers and sea.
The meter meets IP67 standards (30 minute immersion at a depth of 1 m) and
the multisensor probe meets IP68 standards (continuous immersion in water).
