HI 98594 Multiparameter Meter with Bluetooth Connectivity

HI-98594 Advanced Multiparameter Meter Features

Precision in your palm

The HI-98594 is an advanced, highly accurate handheld meter, providing a rugged and practical solution for measuring water anywhere. The handheld design of this meter allows it to be utilised in a wide range of environments, with a portable carrying case to enable convenient movement to different sites.

Reliable water testing anywhere

This handheld advanced water analysis meter is designed to withstand a wide range of environments and applications, from groundwater analysis to aquaculture monitoring. The multi-sensor probe includes all the necessary sensors for simultaneous measurement, ensuring accuracy in testing results across multiple parameters.

Measure 14 parameters

The HI-98594 is equipped with a multi-sensor probe for the measurement of 14 key water parameters, with the ability to display from 1 to 12 parameters at once on the screen. These parameters include:

• pH
• mV
• ORP
• Dissolved Oxygen (ppm)
• Dissolved Oxygen (%)
• EC
• EC (absolute)
• Resistivity
• TDS
• Salinity
• Seawater σ
• Turbidity
• Atmospheric Pressure
• Temperature

Multi-sensor probe for ease of use

The HI-7698594 probe provides an easy-to-use solution for testing multiple parameters at once. This pre-installed probe includes a combined pH/ORP sensor, a combined EC/Turbidity sensor, an Optical Dissolved Oxygen sensor and a temperature sensor as standard. Simple, screw-type, colour-coded connectors and automatic sensor identification make swapping and changing sensors simple.

High precision everywhere you go

The compact, handheld size of the HI-98594 makes it easily portable and convenient in even the most challenging environments. The addition of a rugged carrying case with a thermoformed, moulded interior ensures all accessories and solutions can be securely stored and easily moved.

Data logging capability

The HI-98594 water parameter meter has the capacity to store up to 50,000 samples at intervals between 1 second and 3 hours. Long-on-demand is available to store measurement data, and all logged information is transferred in a universal .csv format on connection to a computer. No additional software is required to extract data.

Smart solutions for smarter testing

Bluetooth 5.0 connectivity enables the HI-98594 to send data directly to the Hanna Lab application, for completely remote access and transfer via smartphone or tablet. Log-on-demand and automatic logging are available for all parameters, and data can easily be reviewed and shared as an email, removing the time delay typically required to pass data on from fieldwork.  

Automatic firmware updates for the meter and probe are available directly through the Hanna Lab app, requiring no computer connection to ensure the meter is up-to-date.

Quick-DIN for waterproof connection

This multiparameter handheld meter connects to the included probe through a single waterproof Quick-DIN connector, making attaching and removing the probe a quick and easy task. The meter automatically detects the probe when connected, with no additional steps required.

Easy transfer and charging

A standard USB Type-C port allows for the easy transfer of data to a memory stick, PC, or other compatible devices. This port is also used to charge the internal lithium-ion battery.

Dual-power supply for continual testing

The HI-98594 features a built-in lithium-ion battery that provides the primary charge for the instrument. A secondary power source, 1.5 AA alkaline batteries, ensures continued operation of the portable water meter when the lithium-ion battery runs out, with automatic switching for seamless measurement.
