muarah, Hanna HI 99141

Hanna HI 99141 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 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.
