The PHB23 is has a non-volatile memory (E2PROM), that stores your set-up values.
Even under a loss of power condition your records are maintained. The menus are
self-explanatory for easy operation and programmed from a simple 3 key face.
The PHB23 also has advanced features like automatic electrode check and battery
status displays. The displayed readings can be continuous, held or logged to memory.
A user programmable audible alarm is included for minimum and maximum alerts.
For ISE, the following curves are already built in: Fluoride, Iodine, Nitrate, Potassium,
Silver, Sodium, Sulfide, H+, Ammonia, Ammonium, Bromide, Cadmium, Calcium, Lead,
Cyanide, Chloride, Copper and four other ions can be user programmed.
