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.
Maintenance-Free, Gel-Filled Electrode
No fill solution required.
