Plating PH Portable Meter - HI99131

The HI99131 is a waterproof, portable pH and temperature meter specifically designed for use in plating baths. The HI629113 pre-amplified, double junction pH probe features a recessed flat tip that is easy to clean and prevents solids in solutions from collecting on the sensor. The titanium body of the HI629113 functions as a potential matching pin for increased stability of readings and extended sensor life.

Unbreakable Titanium Body

Maintenance free gel filled electrode

Titanium construction provides an unbreakable structure and allows the transfer of heat to the internal temperature sensor for rapid temperature compensation.

Maintenance-Free, Gel-Filled Electrode

No fill solution required.
