The HI98190 is a rugged, portable pH meter with the performance and features of a benchtop. This professional, waterproof meter complies with IP67 standards and measures pH, ORP and temperature. The HI98190 is supplied with all necessary accessories to perform a pH/temperature measurement packaged into a durable carrying case.
- CAL Check™ Calibration Diagnostics
- Waterproof Quick Connect
- Ergonomic, One-Handed Operation
For the measurement of pH, the HI98190 comes with an HI12963 titanium body amplified pH electrode with a built-in temperature sensor for automatic temperature compensated readings. The titanium probe body is chemically resistant to aggressive chemicals and is virtually unbreakable. The HI12963 pH/temperature electrode features a newly designed Quick Connect DIN connector that provides a simple waterproof connection without any threads.
Hanna’s unique CAL Check™ feature alerts the user to potential problems during the calibration process. By comparing previous calibration data to the current calibration, the meter will alert the user with display prompts when the probe needs to be cleaned or is broken, and if the pH buffer might be contaminated. After calibration, the overall probe condition is displayed as a percentage from 0 to 100% in increments of 10%.
The probe condition is affected by both the offset and slope characteristics of the pH electrode and is displayed on the measurement screen on the day of calibration and in the GLP data. Calibration can be performed up to five points with seven preprogrammed standard pH buffers and five custom ones to achieve a pH accuracy of ±0.002 with ±0.001 pH resolution.
Our extensive setup screen features a host of configurable options such as time, date, temperature units and language for help screens and guides.
pH calibration features detailed CAL Check™ messages. Users are guided through the calibration procedure with step-by-step on-screen instructions.
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.
