HI99111 is a portable, microprocessor‑based pH and
temperature meter. Main features include: extended pH
and temperature ranges; waterproof and compact casing;
large dual‑line display; low battery detection; automatic
pH calibration at one or two points within two memorized
buffer sets (standard or NIST); selectable temperature
unit (°C or °F).
The HI10483 pH probe features an open junction with
Clogging Prevention System (CPSTM) technology, has a
built‑in temperature sensor for simultaneous temperature
compensated pH and temperature readings, and also
contains an integral pH sensor preamplifier to provide
measurements impervious to noise and electrical interferences
