Hanna Instruments multiparameter meter pH/EC/TDS/°C HI991300
The versatile and robust measuring device is ideal for measuring several important parameters in one step. With pH, EC, TDS and temperature measurement, it covers a wide range of applications in water analysis and laboratory environments. Despite its extensive functions, the device is easy to operate, making it the preferred choice in many areas. Similar to the Hanna Instruments Edge® EC/Salinity measuring device, a clearly structured display makes it easy to read multiple values at the same time.
Versatile functions for demanding measurement tasks
This device is particularly practical for laboratories, research facilities and service providers who frequently test water, waste water or process liquids. Thanks to its Quick DIN connection probe, it is easy to transport and is also suitable for mobile use in field studies or for random sample measurements. Unlike some entry-level devices, the reinforced HI12883 probe offers reliable long-term stability.
- Robust IP67 housing protects against dust and water
- Multilevel display shows pH, EC, TDS and temperature simultaneously
- Automatic temperature compensation for precise measured values
- One or two-point calibration in pH mode (two sets of standard buffers available)
- Simple, purpose-built operation with just two buttons
- Quick coupling with rubber seal for secure connection of the probe
- Battery operation with up to 600 hours of operating time
In addition, an application-specific range of electrodes is available to optimally adapt measurements to the respective sample. The pH glass membrane and the conductivity sensors are designed for a low EC range, which is why the system is not only recommended for laboratory use, but also for applications for monitoring drinking water or ultrapure water. Another advantage is the automatic switch-off, which can be set after 8 or 60 minutes of inactive operation to save batteries.
Certifications and standards
During the development process, attention was paid to durable processing in accordance with IP67 so that the entire device is dustproof and waterproof. Thanks to the robust design, users can rely on precise results in a wide range of environments. Relevant safety and quality standards are integrated into the design and described in more detail in the manufacturer's documentation, which is particularly important in laboratory environments.
Concrete application examples
- Check water quality in the laboratory: Ideal for pH and conductivity measurements in research projects or routine tests.
- Agricultural analysis: Determination of the salt content (TDS) in soils and fertilizer solutions to provide plants with optimum nutrition.
- Maintenance of cooling circuits: Monitoring pH value and conductivity to prevent corrosion or deposits.
- Drinking water analyses: Regular checks to ensure compliance with legal requirements, such as pH value or dissolved solids.
Reliable calibration is essential in these areas in particular. The one- or two-point pH calibration process works with buffers according to the standard (pH 4.01 and 7.01 or 4.01 and 10.01) as well as with alternative buffer sets such as pH 4.01 and 6.86 or 9.18. For EC and TDS, calibration is carried out with known conductivity buffers (1413 µS/cm) or 1382 or 1500 ppm.
FAQ
How often should the device be calibrated?
Calibration before each new series of measurements is recommended. With intensive use or changing sample conditions, daily calibration may be necessary.
Is regular maintenance required?
The probe should always be kept clean, especially after measurements in contaminated media. Cleaning solutions in the starter kit facilitate this maintenance. Regular replacement of the electrodes is only necessary if there are false readings or an unstable measured value.
What needs to be considered when storing the probe
Storing the pH probe in an appropriate storage buffer extends its service life. If the glass membrane dries out, measurement errors may occur.
How accurate are the TDS values?
The accuracy is ±2 % of the full measuring range. In addition, the conversion factor from conductivity to TDS can be adjusted to achieve even more precise results.
Can the device be used outdoors?
Yes, thanks to protection class IP67 it is protected against dust and short-term submersion. However, the measuring accuracy may be impaired at temperatures below -5 °C or above 150 °C.
Conclusion
The measuring device combines several essential measurement parameters in a single, compact housing. Safe waterproofing, flexible calibration options and the durable, reinforced probe ensure reliable data even in demanding outdoor applications. Practical features such as the multi-level display and ergonomic two-button operation make it suitable for use in a wide range of industries, for example in laboratories, process monitoring or drinking water monitoring. The system not only makes life easier for the user thanks to its simple handling, but also quickly delivers precise results for pH, EC, TDS and temperature measurements.
