Precision in Your Hands
Reliable Water Analysis Anywhere You Are
The HI98594 is designed to withstand harsh environmental conditions, making it the ideal tool for field analysis. Thanks to its combined EC/turbidity sensor, the HI98594 not only measures up to 14 parameters but also introduces innovative technology that sets a new standard in Hanna Instruments' multiparameter range.
The device is IP67 certified, ensuring protection against temporary immersion up to 1 meter for 30 minutes. The multisensor probe, on the other hand, is completely sealed and meets IP68 standards, making it suitable for continuous immersion.
This instrument is perfect for a wide range of applications, including the analysis of surface, marine, wastewater, and groundwater, as well as aquaculture, research, and environmental remediation. With the HI98594, you’ll always have reliability and precision at your fingertips.
Measures 14 Parameters
The HI98594 can measure 14 essential water analysis parameters:
•pH •mV •ORP •DO (ppm) •DO (%) •EC •Absolute EC •Resistivity •TDS •Salinity •Seawater σ •Turbidity •Atmospheric Pressure •Temperature
The HI98594 allows users to display between 1 and 12 parameters simultaneously, which can be configured to their preferences. Its readings are easily legible even in challenging environments, such as under direct sunlight, thanks to the backlit screen that ensures optimal visibility in all conditions.
