HI98191

Description

The HI98191 is a rugged, portable pH/ORP/ISE meter with the performance and features of a benchtop meter. This professional, waterproof meter complies with IP67 standards and measures pH, ORP, ISE, and temperature. The HI98191 is supplied with all necessary accessories to perform a pH/temperature measurement packaged into a durable carrying case.

• CAL Check™
• Ergonomic, One-Handed Operation
• ISE in Choice of Concentration Units

AutoHold
• Freezes a stable reading on the display for recording or logging

  Calibration
•  pH calibration features detailed CAL Check™ messages.
•  Alerts user to potential problems during calibration including when to clean electrode and possible buffer contamination.

Connectivity
• PC connectivity via a sealed opto-isolated micro USB and HI92000 software

GLP
• Comprehensive GLP functions are directly accessible by pressing the GLP key. Calibration data, including: date, time, offset, slope and buffers used in the
last calibration can be reviewed.

ISE Measurements
• The HI98191 includes ISE measurements when used with our wide selection of ISE electrodes or a custom version.

Log-on-demand
• Store measurement data at the press of a button

pH CAL Check™
• Alerts user to potential problems during calibration including when to clean electrode and possible buffer contamination.
• Displays overall probe condition based on offset and slope after calibration

Setup Screen
• Our extensive setup screen features a host of configurable options such as time, date, temperature units and language for help screens and guides.
