Discover the new portable multiparameter Bluetooth meter HI98594
10/01/2025
The HI98594, designed to withstand harsh environmental conditions, measures 14 parameters and is ideal for field measurements. Within the Hanna Instruments family of multiparameters, it stands out for its ability to measure turbidity.

Measure 14 parameters
HI98594 can display from 1 to 12 parameters simultaneously, selectable by the user.
- pH, mV
- ORP
- Dissolved oxygen (ppm), dissolved oxygen (%)
- EC, EC (absolute), resistivity, TDS
- Salinity, seawater σ
- Turbidity
- Atmospheric pressure
- Temperature
High precision wherever you go
- The compact size of HI98594 ensures easy portability and convenient use, even in the most challenging environments.
- HI98594 is supplied with rugged carrying case, designed to provide years of use and maximum protection. The inside compartment of the carrying case is thermoformed to securely hold and protect all of the components

Multi-sensor probe with advanced performance
HI7698594 has three screw type connectors that are color coded for easy and automatic sensor identification. It is supplied with protective shield, and its waterproof design makes it ideal for difficult application.
- Pre-installed pH/ORP, EC/Turbidity and optical DO sensors
- Sensor replacement is quick and easy


Smart solutions for smarter water testing
- Log on demand and automatic logging for all parameters: HI98594 allows to log one data point or continuously log at selected time intervals. All logs have the option to store data into a named lot and the ability to add comments
- Bluetooth 5.0 connectivity and Hanna Lab: Using the Bluetooth connection and Hanna Lab app, logged data batches can be easily transferred to a smart device for review or shared as an e-mail. Automatic firmware updates for the meter via the Hanna Lab app.
Enhance your analysis with the flow cell
- Improves analysis accuracy: ensures optimal contact between sensors and the sample. It also avoids the introduction of air or pressure variation, which could alter the composition of the sample
- Field monitoring: perfect for in situ monitoring and sampling, including low-flow sampling for groundwater monitoring
- Robustness: high-quality materials that guarantee long life and resistance to wear
