Backlit graphic LCD display - The HI98194 features a backlit graphic LCD with on-screen help function and can display up to 12 parameters simultaneously. The graphic display allows the use of virtual keys to provide an intuitive user interface.
Waterproof protection - The meter is enclosed in an IP67-rated waterproof housing and can withstand immersion in water up to 1 meter deep for up to 30 minutes. The probe has IP68 protection and can be continuously immersed in water.
Quick-connect digital probe - The HI7698194 probe features a quick-connect DIN connector for waterproof connection to the meter.
Color-coded, field-replaceable sensors - Quickly and easily replace sensors using field-replaceable screw-type connectors that are color-coded for easy identification of sensor ports.
Automatic sensor recognition - The probe and meter automatically recognize connected sensors. Any unused port on the probe will not display parameters or allow configuration of that parameter.
Automatic temperature compensation - The integrated temperature sensor allows automatic temperature compensation for pH, conductivity, and dissolved oxygen measurements.
Automatic barometric pressure compensation - The meter has a built-in barometer, and the user can select the unit used for dissolved oxygen pressure compensation.
Standard or quick calibration - Quick calibration allows fast single-point calibration for pH, conductivity, and dissolved oxygen. The standard pH calibration option can be used to calibrate three points selected from five standard buffers and one custom buffer. Conductivity calibration is a single-point calibration from six standard selections or one custom standard. Dissolved oxygen calibration can calibrate up to two standard points or a single custom point.
GLP data - The HI98194 includes a GLP function that allows the user to view calibration data and expiration information by touching a key. Calibration data includes date, time, buffer/standard solution used for calibration, and slope characteristics.
Data logging - The HI98194 allows the user to store up to 45,000 continuous or on-demand log samples, with logging intervals from one second to three hours.
Intuitive keypad - The installed rubber keypad features dedicated power, backlight, up/down arrows, help, and alphanumeric characters. The meter also has two virtual soft keys that guide the user through configuration, meter setup, and data logging for each parameter. The interface is intuitive for any user's level of experience.
Dedicated help key - Context-sensitive help is always available through the dedicated "HELP" key. Clear tutorial messages and instructions are provided on the screen to quickly guide the user through setup and calibration. The displayed help information is relevant to the setting/option being viewed.
PC connection - Using the included HI920015 micro USB cable and HI9298194 software, logged data can be transferred to a Windows-compatible PC.
Long battery life - The meter's display has a battery icon indicator to show remaining power. The meter uses four 1.5V AA batteries and provides up to 360 hours of battery life.
Rugged thermoformed carrying case - The HI98194 meter, probe, and all accessories are supplied in a rugged carrying case designed to provide years of use. The interior compartments of the case are thermoformed to securely hold and protect all components.

Case Studies
Municipal Wastewater Treatment · Hanna — Stock Configuration Case
Project Overview
The site is the inlet, biological and outlet stages of a municipal plant. The customer wanted Hanna properly configured on the existing plant, with the aim of covering portable and laboratory water testing with Hanna instruments.
Technical Challenges
What actually causes trouble is high solids and corrosive fractions, with large diurnal flow swings, and effluent parameters drift and probes foul with sludge and biofilm. All of this means the Hanna configuration has to involve selected by parameter set, accuracy and field portability.
Configuration
Supply and installation were organised through the stock channel: configuring from stock and delivered quickly. On site this meant selected by parameter set, accuracy and field portability, checked line by line against: stable compliance with Grade 1A discharge limits and online data reporting.
Performance
After commissioning the outcome is results available on site, reducing lab re-checks, and the readings are now used for process tuning.
Food & Beverage · Hanna — Stock Configuration Case
Site Conditions
This is a Food & Beverage customer whose plant is at dosing, pasteurising, filling and CIP stages. The main task was covering portable and laboratory water testing with Hanna instruments.
The Problem
The difficulty lies in syrups, dairy and beverages that scale easily, under strict hygienic requirements; at the same time frequent cleaning demands instruments that withstand hot CIP/SIP caustic cycles. Specification therefore means selected by parameter set, accuracy and field portability.
What We Did
We took a stock channel approach — configuring from stock and delivered quickly. Delivery was built around selected by parameter set, accuracy and field portability, with point-by-point checks on: food-safety and hygienic design per 3-A / EHEDG.
Operating Outcome
In service the system performs as intended — results available on site, reducing lab re-checks, with routine maintenance falling noticeably.
Chemical & Pharmaceutical · Hanna — Stock Configuration Case
Application Context
reactors, metering vessels and finished-product tanks is a typical Chemical & Pharmaceutical duty. The project started from Hanna, focusing on covering portable and laboratory water testing with Hanna instruments.
Process Constraints
corrosion plus Ex protection shortens instrument life and makes downtime costly, and highly corrosive media with solvents and crystallisation, partly in explosive atmospheres only amplify it. The Hanna specification must therefore cover selected by parameter set, accuracy and field portability.
Delivery Approach
Delivery was handled as the stock channel — configuring from stock and delivered quickly. Execution centred on selected by parameter set, accuracy and field portability, together with Ex certification and GMP traceability of records.
Field Results
Operation shows the benefit clearly — results available on site, reducing lab re-checks, with confidence in this measuring point improving markedly.
Power & Energy · Hanna — Stock Configuration Case
Customer Profile
The typical setting in Power & Energy is boiler feedwater, turbine condensate and FGD/DeNOx systems. The measuring point is Hanna; the focus is covering portable and laboratory water testing with Hanna instruments.
Key Difficulties
Conditions are high temperature and pressure with both steam and saline water and, on top of that, drift under high temperature and pressure, with very costly unplanned outages, which a standard configuration cannot handle for long. The design therefore starts with selected by parameter set, accuracy and field portability.
Implementation
The scope ran through the stock channel: configuring from stock and delivered quickly. Technically it hinges on selected by parameter set, accuracy and field portability, and on these requirements: compliance with power-industry codes and unit availability targets.
Customer Benefit
In practice this means results available on site, reducing lab re-checks, which cut the workload on the site maintenance team.
