Hanna Instruments Portable pH meter for electroplating HI99131
This portable measuring device enables reliable pH and temperature measurements to be carried out in electroplating baths, allowing process sequences to be optimized particularly efficiently. A key advantage over other measuring instruments is the specially developed stainless steel electrode, which handles samples rich in solids with ease. Similar features to the [Hanna Instruments pH meter HI99141] also offer a robust design, but the device presented here is particularly suitable for use in electroplating solutions thanks to its flat sensor tip. Anyone measuring in demanding, industrial environments will benefit from the quick handling and long battery life.
Robust and precise measuring solution
The device has been specifically designed to meet the challenges of electroplating processes, which often involve temperatures of up to 105 °C and a wide range of pH values. The ring-shaped PTFE cable prevents clogging by dissolved solids, while the stainless steel housing of the electrode retains its full functionality even at higher temperatures. Similar to the [Hanna Instruments pH meter HI98107], the Quick DIN connection provides a watertight interface that both extends the life of the device and allows for quick maintenance.

- Large LCD: Allows pH and temperature values to be read quickly
- Simple operation: Only two buttons for setting and measurement
- Automatic switch-off: Energy-saving, optionally after 8 or 60 minutes
Examples of use
- Monitoring pH values in electroplating and coating baths to maintain optimum process conditions.
- Regular quality control in metal processing to detect deposits or contamination at an early stage
- Check the pH value in electroplating test solutions in research and development when chemical additives such as nickel or copper sulphate are used.
- Control of temperature and pH in electroplating electrolytes to ensure uniform metal deposition
Frequently asked questions (FAQs)
How often should I calibrate the electrode?
For intensive use in electroplating baths, daily or weekly calibration is recommended, depending on the purity of the measurement sample and the in-house requirements. Those who require particularly accurate values should ideally calibrate before each series of measurements.
Which buffer sets can be used?
Two sets of standard buffers are available: (pH 4.01; 7.01; 10.01) or (pH 4.01; 6.86; 9.18). This ensures reliable one or two-point calibration at all times.
Can the device also be used in a damp environment?
Thanks to the IP67 housing, the device is protected against water and dust. It can be used in damp and demanding production environments without compromising measurement quality or service life.
When is it necessary to replace the electrode?
As soon as the display reports recurring error values or a critical electrode condition, it is advisable to clean or replace the electrode. The device itself indicates potential problems with a status display.
How long do the batteries last?
The 1.5 V AAA batteries provide around 1400 hours of continuous operation. The automatic switch-off function after 8 or 60 minutes extends this runtime even further.
Conclusion
The portable pH meter meets all the requirements for professional pH and temperature monitoring in electroplating baths. The robust stainless steel electrode, IP67-protected housing and reliable measurement accuracy make it ideal for industrial applications. Thanks to the ergonomic design and user-friendly operating concept, measurements can be carried out efficiently and safely even in harsh working environments. The durability of the installed components and the quick and uncomplicated maintenance are particularly impressive. Ultimately, the Hanna Instruments Portable pH Meter for Electroplating HI99131 is the ideal solution when permanent and precise pH value control is required in industrial processes.
