อุปกรณ์วัด pH (Portable pH Meter for Boiler and Cooling Towers)

HI 99141

Portable pH Meter for Boiler and Cooling Towers

HI 99141 is a waterproof, portable pH/ temperature meter supplied with a flat tip probe specifically designed for boiler and cooling tower applications.

The HI 72911D 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 HI 72911D functions as a potential matching pin for increased stability of readings and extended sensor life.
