Hanna Instruments Portable pH Meter for Boilers and Cooling Towers HI99141
Thanks to its specialized design, this meter provides accurate measurements, making it particularly suitable for use in challenging environments such as boiler and cooling tower systems. Similarly flexible as the [Hanna Instruments Portable pH Meter HI99121], this model also shows its strengths in frequent pH checks that occur daily in industrial laboratories as well as in process monitoring. With its waterproof housing, robust stainless steel electrode and ring-shaped PTFE diaphragm, it clearly stands out from other devices on the market, increasing both measurement accuracy and durability.
Versatile properties for demanding measuring tasks
The intuitive operation with just two buttons ensures that users can quickly familiarize themselves with the menu navigation. The electrode has been specially developed for use in boiler and cooling tower systems. The flat sensor design largely prevents deposits of dissolved solids and simplifies cleaning. Even in harsh working environments, the IP67-compliant housing shows that it is designed for industrial requirements. For additional safety, the integrated electrode status display provides information on the current status of the pH electrode.
To ensure maximum flexibility, the meter has an extended measuring range that records both pH values and mV data. Automatic temperature compensation (-5 to 105 °C) helps to ensure that results remain consistent and accurate even in changing conditions. With the quick connection (Quick-DIN), users save time as the electrode can be connected or disconnected without screw connections.- pH measuring range: -2.0 to 16.0 / -2.00 to 16.00
- pH accuracy: ±0.02 / ±0.1
- mV measuring range: ±825 mV
- Temperature measuring range: -5 to 105 °C
- Vibration and splash water protection thanks to IP67 housing
- Automatic switch-off after 8 or 60 minutes (can be deactivated)
- Battery life of up to 1400 hours for long, uninterrupted use
In addition, the device offers a useful combination electrode made of stainless steel, whose ring-shaped PTFE diaphragm minimizes contamination. During operation, the easy-to-read LCD display keeps users informed of measured values, electrode status and battery status at all times. The flexible one- or two-point calibration ensures reliable results in various buffer ranges (4.01/7.01/10.01 or 4.01/6.86/9.18). As the device is suitable for temperatures of up to 105 °C, it can also be used in boilers and process engineering systems with increased system temperatures without any problems.
Certifications and standards
The resistant housing with IP67 is suitable for industrial areas where splash water or moisture are common. As the built-in components are consistently designed for long-term measurement stability, professionals benefit from a high level of reliability without necessarily having to resort to additional protective measures.
Concrete application examples
- Continuous pH control in boiler water systems to monitor corrosion and limescale formation processes
.
- Ensuring the correct water chemistry in open and closed cooling towers, for example in air conditioning systems or industrial heat exchangers.
- Measurements in industrial processes where robust sensor technology is required, such as when adding chemicals for pH regulation (e.g. caustic soda or hydrochloric acid).
- Use at critical points in the process chain to detect and prevent deposits and damage caused by incorrect pH values in good time.
FAQs
How often should the electrode be calibrated?
The electrode should ideally be calibrated before each series of measurements or at least once a day. More frequent calibration is recommended for intensive use and large temperature fluctuations.
Can the device only be used in boiler and cooling tower systems?
Although it is specially designed for this purpose, it is also suitable for general pH measurements in other industrial areas. The robust design reduces the risk of damage and contamination in almost any application.
Do you need additional accessories to be able to measure reliably?
The scope of delivery includes a starter set of calibration and cleaning solutions. However, for maximum device protection in very harsh operating conditions, we recommend the HI710029 rubber protective cover, which is available as an option.
How can the condition of the electrode be assessed without laboratory tests?
The integrated electrode condition detection system shows on the display whether the electrode is still working properly. If necessary, it should be replaced to avoid measurement errors.
Conclusion
This measuring device combines easy handling, robust design and precise measurements in a compact system. It is ideal for pH monitoring in boiler and cooling tower systems thanks to its special stainless steel electrode with flat sensor contact. The automatic temperature compensation, waterproof quick connection and IP67 housing make it a reliable companion in demanding environments. Anyone looking for a durable, user-friendly and highly functional instrument for frequent pH checks in industrial processes will find a convincing solution here.
