Hanna Instruments multiparameter meter for pH/conductivity HI98195
The Hanna Instruments HI98195 multiparameter meter for pH/conductivity is ideal for the professional measurement of pH, redox potential, conductivity and temperature in laboratory and industrial environments. It combines a robust design, extensive calibration options and intuitive operation to ensure accurate measurement results even in harsh environments. Similar to the [Hanna Instruments multi-parameter measuring device HI98194], this system offers reliable data acquisition directly on site and thus ensures improved analysis of the water quality in the ongoing process.
Versatile measurement functions for everyday needs
The device covers up to nine key measurement parameters. It enables measurements of pH, redox (ORP), conductivity, total dissolved solids (TDS), salinity, resistance and temperature. This ensures a wide range of applications in water analysis, environmental monitoring and process control. Particularly noteworthy are:
- Automatic detection of sensors used by the digital probe, which avoids configuration errors
- Robust housing with protection class IP67 (probe IP68), ideal for outdoor use.
- Backlit graphic LCD that displays measured values and help texts.
- Quick or standard calibration for pH and conductivity in just a few steps.
- Data storage of up to 45,000 values, incl. GLP functions for later evaluation.
- PC connectivity via micro USB for convenient data transfer.
- Long battery life of up to 360 hours with constant measurement.
The probe transmits all measured values digitally, which effectively reduces measurement errors and signal interference. The Quick-Connect DIN connection allows cables up to 40 meters long to be connected quickly and watertight. Color-coded connections also ensure easy sensor installation without the risk of confusion in the field.
Reliable technology and standards
The hand-held measuring device records pH values in the range from 0.00 to 14.00, redox potential up to ±2000 mV and conductivity up to 200 mS/cm. It complies with common standards, supports GLP-compliant documentation and is characterized by very low measurement deviations (±0.02 pH, ±0.5 mV for pH range). The automatic temperature compensation (ATC) ensures that pH and conductivity measurements in particular remain precise - even under changing ambient conditions. Thanks to the IP67 classification, the device can easily withstand splash water, dirt and brief immersion in liquids. The probe itself is IP68-certified and can therefore remain permanently under water.
Examples of use in practice
- Water treatment: Thanks to integrated conductivity measurement, the salt concentration in cooling circuits or water treatment systems can be monitored precisely and corrected in good time.
- Environmental monitoring: In lakes, rivers or at groundwater measuring points, the measuring device provides reliable data on pH and TDS development.
- Laboratory analysis: The high accuracy and optional multi-point calibration of the pH electrode enable precise measurements in research and test laboratories.
- Process control: Live monitoring in industrial processes, where parameters such as pH or salinity can change rapidly, enables quick adjustments and ensures quality standards.
Typical substances that can be monitored particularly well with the device include various electrolytes, coolants, rinsing liquids in the food industry and also salt water in fish farming.
Frequently asked questions
How often does the device need to be calibrated?
The calibration intervals vary depending on the area of application. In general, regular calibration (e.g. weekly or monthly) or before each critical measurement is recommended to ensure maximum accuracy
Can I also use the device permanently in a process environment?
Yes. The hand-held measuring device has protection class IP67, the probe even IP68. This means it can be used for longer periods under difficult conditions without any problems.
Which calibration solutions are needed?
The HI9828-25 solution is used for quick calibration. In addition, standard buffers (e.g. pH 4.01, 7.01, 10.01) or user-defined buffer sets can be used for multi-point calibration.
How to connect the device to the PC
The integrated micro USB interface enables easy data transfer. Measurement data can be exported and analyzed using the HI9298194 software.
Summary
The multiparameter handheld meter is characterized by precise and reliable measurement performance for pH, conductivity, redox and temperature. It is designed to be waterproof, shock-resistant and user-friendly, which is particularly beneficial in harsh working environments. Thanks to a wide range of calibration options, clear data storage and automatic error detection for the sensors, the robust system covers both laboratory and field applications. With its extensive features and long-lasting battery power, it delivers consistent measurement accuracy even under the most demanding conditions - an indispensable instrument for professional water and process analysis.
