HI98494 Multiparameter Bluetooth® portable pH/EC/OPDO Meter


HI98494 is a waterproof portable logging multiparameter meter that monitors up to 12 different water quality parameters including 6 measured and 6 calculated.  The microprocessor based multi-sensor probe allows for the measurement of key parameters including pH, ORP, conductivity, dissolved oxygen, and temperature. The probe transmits readings digitally to the meter, where data points can be displayed and logged. Data logged in the meter can be transferred by Bluetooth® to a smart device with the Hanna Lab App installed. The HI98494 is supplied with all necessary accessories and packaged in a durable carrying case.

  • Bluetooth® Connectivity
  • OPDO: Optical Dissolved Oxygen Technology
  • 12 Parameter Dot Matrix Display

Measurements & Logging

Measure up to 12 parameters. Don’t lose important data with automatic interval logging of up to 45,000 samples or choose to log-on-demand to store measurement data for key points.

Dual Power Source

The meter operates on a built-in lithium-ion battery and will automatically switch to AA alkaline batteries for at least 200 hours of testing.

GLP Data

For better traceability, calibration information is recorded along with a time and date stamp and stored with logged data.


Quick Calibration provides a speedy, single point calibration for pH, conductivity, and dissolved oxygen. Standard calibration options are also available.

Built to be Durable

Designed to withstand the knocks, drops, and spills of real life, the IP67 body ensures top performance in any environment. These meters are protected against dust and water intrusion from any direction.

Quick Connect Probe

A Quick Connect DIN connector makes attaching and removing the probe simple and easy. The rubber coating protects the cable and provides a water-tight seal without twisting.


Data Transfer & Charging

The USB Type-C port provides for easy data transfer to memory stick, PC, or other device and is used to charge internal lithium-ion battery.

Digital Probe

Digital probe with built-in temperature sensor and three ports for pH (ORP), EC and optical DO sensors. Once connected, the meter automatically recognize the sensors.

Multiparameter Probe and Sensors

Sensor replacement is quick and easy with field replaceable, screw type connectors and are color-coded for easy identification.




Connect in the Field

Connect wirelessly via Bluetooth® to your smart device running the Hanna Lap App.


Measurement & Graphing

Select the measurement units to be displayed on your smart device. For trend analysis, take a look at the graph of your logged data.

Good Laboratory Practice (GLP)

Comprehensive GLP data can be reviewed for all parameters when the logged data is downloaded to your smart device.

Sort & Share

Group your data by time or notation. Email it for storage or share it with friends or colleagues.
