Product Description

The HI99141 is a waterproof, portable pH and temperature meter specifically designed for boilers and cooling towers. The HI72911D pre-amplified double junction pH probe features a flat tip sensor that is easy to clean and prevents solids in solutions from collecting on the sensor. The titanium body of the HI72911D functions as a potential matching pin for increased stability of readings and extended sensor life.
