Plating pH Portable Meter - HI99131

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.

Automatic Temperature Compensation
Automatic Two-Point Calibration
Waterproof

Unbreakable Titanium Body

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