HANNA HI991001N Extended Range Portable pH Meter

HI 991001N measures pH/ temperature.
The HI 1296D pH probe feature a recessed flat tip that is easy to clean and prevents solids in solutions from collecting on the sensor. The titanium body of the probe functions as a potential matching pin for increased stability of readings and extendedsensor life. The HI 991001N easily fits in the palm of your hand and the bottom probe connection ensures the electrode cable doesn’ t get in your way. The large, multi-level LCD displays the primary reading, temperature and calibration instructions simultaneously.
