GENERAL DESCRIPTION

HI 991002 is a portable, microprocessor-based pH/ORP/
temperature meter.
Main features include: extended pH, mV 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 pH electrode 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. The mV range is also available.
Each meter is supplied with:
• HI 1297D pH/ORP probe with internal
temperature sensor, DIN connector and 1m (3.3') cable
• Calibration & cleaning solution sachets
• 3 x 1.5V AAA batteries
• Instruction manual.
