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 instrumentfunctions correctly. Any damaged or defective items must be returnedin their original packing material with the supplied accessories.1.2 MODEL IDENTIFICATIONHI 98194 pH/EC/DO Multiparameter meter with HI 7698194 probe.HI 98195 pH/ORP/TDS/NaCl/Resistivity meter with HI 7698195 probe.HI 98196 pH/ORP/Dissolved Oxygen meter with HI 7698196 probe.1.3 GENERAL DESCRIPTIONHI 9819X is a portable logging multiparameter system (instrument, probe) thatmonitors up to 14 different water quality parameters (7 measured, 7 calculated).The microprocessor-based intelligent multisensor probes allows measurement ofmany water quality parameters such as pH, ORP, dissolved oxygen, conductivityand 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 thedigits to fit the screen with on-screen graphing capability. Each parameter is fullyconfigurable.HI 9819X was designed to withstand harsh environments and is the ideal solutionfor field measurements of lakes, rivers and sea.The meter meets IP67 standards (30 minute immersion at a depth of 1 m) andthe multisensor probe meets IP68 standards (continuous immersion in water).
