HI 991003 is a portable pH/pH-mV/ORP/
temperature meter, with unique Sensor
Check feature, that allows the user to de-
termine the electrode status at any time.
Main features also include: extended mea-
surement ranges; waterproof and compact
casing; large dual-line LCD; low battery de-
tection; automatic pH calibration at one or
two points with two memorized buffer sets;
selectable temperature unit (°C or °F).
The pH/ORP electrode has a built-in tem-
perature sensor for simultaneous pH (or
mV) and temperature readings, and also
contains a mini amplifier to render mea-
surements impervious to noise and elec-
trical interferences.
Each meter is supplied complete with
•
HI 1297D pH/ORP/temperature probe with
DIN connector and 1 m (3.3’) cable
•
calibration & cleaning solution sachets
•
3x1.5V AA alkaline batteries
•
instruction manual
•
rugged carrying case.
