HI99141 Portable pH Meter for Boiler and Cooling Towers by Hanna Instruments
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.
- Dedicated to boiler and cooling tower applications
- Flat-tipped, pre-amplified pH probe with titanium body
- Multi-level LCD display
- On-screen tutorial messages for calibration and set-up
- Automatic Temperature Compensation
- Automatic one or two point calibration
- BEPS (Battery Error Prevention System) alerts the user in the event that low battery power could adversely affect readings
- Battery % displayed on startup.
- Compact, heavy-duty, and waterproof
- Easy to clean flat-tip sensor
