Product description

The HI98191 professional pH meter is a waterproof portable multiparameter meter designed for accurate water analysis in laboratory and field environments. It measures pH, ORP (mV), ion concentration using ion selective electrodes (ISE), and temperature in one compact device. The rugged housing and intuitive interface make it ideal for demanding professional applications.

An overview of the available ISE Electrodes for the HI98191 Waterproof Portable pH/ORP/ISE Meter can be found on this page.

The exclusive CAL Check™ technology continuously monitors electrode condition and buffer quality to prevent measurement errors. Automatic five-point calibration with standard or custom buffers and automatic temperature compensation (-20.0 to 120.0 °C) ensure precise and reproducible results.

For ion analysis, the HI98191 supports multiple ISE measurement units such as ppm, mg/L, mol/L and % w/v. Up to 300 data points can be stored and transferred via USB for GLP-compliant documentation. This portable water quality meter is supplied in a durable waterproof carrying case and is suitable for environmental, industrial and laboratory testing.
