This is a portable waterproof pH meter for plating baths
The Hanna Instruments HI 99131 is a portable, microprocessor-based pH and temperature meter designed specifically for plating baths. It features a special HI 62911 amplified pH probe with a titanium electrode body that acts as a Faraday cage to ensure stable readings in samples with strong electrical fields. The device includes a built-in temperature sensor for automatic compensation.

All Hanna Instruments meters are warranted for two years against defects in workmanship and materials.
The probes are warranted for a period of six months.
It is recommended to recalibrate at least once a month, or whenever the electrode is replaced or aggressive chemicals are tested.
When the battery level drops below 5%, a symbol blinks on the LCD, and the Battery Error Prevention System (BEPS) will turn the meter off.
