The HI99131 is a waterproof, portable pH and temperature meter specifically designed for use in plating baths. The HI62911D 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 HI62911D functions as a potential matching pin for increased stability of readings and extended sensor life.
