Hanna Instruments compact pH/°C handheld meter HI991001
The Hanna Instruments HI991001 compact pH/°C handheld meter is ideal for precise and reliable pH and temperature measurements in laboratories, production facilities or in the field. Thanks to its robust design and waterproof construction, it is often superior to conventional devices. Similar rugged measurement solutions such as the [Hanna Instruments pH meter HI98103] offer functionality in a compact format, but this model scores with a particularly versatile temperature range and a reinforced electrode for highly accurate readings.
Detailed description
This hand-held meter provides professional measurement functions for pH, mV and temperature values. The integrated amplifier in the HI12963 electrode minimizes interference, which is reflected in accurate and reliable results. In addition, a temperature-sensitive sensor is integrated in the same electrode and ensures fast temperature compensation. Devices such as the [Hanna Instruments pH handheld meter HI98107] also impress with an easy-to-use interface. However, the model presented here is not limited to pure pH or temperature measurements, but supports a measuring range from -2.00 to 16.00 pH and thus enables a wide range of applications.
The most important technical key figures are as follows:
- Measuring range pH: -2.00 to 16.00 with a resolution of 0.01
- Accuracy pH: ±0.02 and automatic one- or two-point calibration
- Reinforced titanium body electrode with Quick DIN connection and integrated temperature sensor
- mV measuring range up to ±825 mV (resolution 1 mV, accuracy ±1 mV)
- Temperature range from -5.0 to 105.0 °C, automatic temperature compensation
- Robust, IP67-compliant housing for the harshest operating conditions
- Operating time: around 600 hours with 3 x 1.5 V AAA batteries
The simplified two-button operation enables intuitive handling: users can quickly switch the device on and off and select settings for different calibration point standards. A large, easy-to-read LCD clearly displays pH, temperature, electrode status and other relevant measurement information. In addition, the electrode is easy to replace thanks to the Quick DIN concept and, together with the rubberized protection of the cable connection, ensures a watertight connection.
The HI12963 electrode type not only offers durability thanks to a titanium body, but also an increased service life with optimum care. The electrode detects reliable measured values even under demanding sample conditions, for example in heavily contaminated liquids or with frequent temperature fluctuations. A practical carrying case as well as cleaning and calibration solutions are included in the scope of delivery.
Certifications and standards
The model has an IP67-compliant outer housing, which reliably protects the measuring device against dust and temporary submersion. This makes it suitable for everyday use in environments that require splash-proof equipment
Application examples
- Monitoring pH values in beverage plants to ensure product quality
- Regular checks in water treatment plants to quickly detect changes in pH and temperature
- Use in laboratories where measurements on chemical solutions such as caustic soda (NaOH) or hydrochloric acid (HCl) need to be monitored precisely
- Field measurements in environmental analysis, for example when examining soil solutions or river water
FAQ
How often should the device be calibrated?
For precise daily values, regular calibration is recommended, preferably once a day or depending on the frequency of use.
What should be observed when cleaning the electrode?
Use the enclosed cleaning solutions to remove stubborn deposits. The electrode should then be rinsed with deionized water and stored in pH electrode storage solution.
Is the device protected against moisture?
Yes, the IP67-compliant housing successfully protects the device against dust and splash water. This means that all functional units remain fully operational even under harsh conditions.
Can I use the device for highly alkaline or acidic samples?
Yes, thanks to the large pH measuring range, even very alkaline solutions and highly acidic samples can be measured reliably. Make sure to rinse the electrodes properly after each use.
Conclusion
This hand-held measuring device offers an optimal combination of robustness, easy handling and reliable measuring accuracy. It is therefore ideal for professional use where fast and precise pH and temperature measurements are required. With its large measuring range, ingenious sensor design and waterproof construction, it is an ideal measuring solution that works reliably even under demanding conditions.
