measurements with automatic range switching when readings
exceed ±399.9 mV. HI 8424 comes supplied with: HI 1230B
combination, double-junction, gel pH electrode, HI 7669AW tem-
perature probe and a 9V battery.
• HI 8915 is a portable pH/mV/°C meter that combines accurate
pH measurements with a recorder output capability and auto-
matic temperature compensation. Two recorder output terminals
make it possible to attach a plotter or recorder directly to the
meter for a hard copy of the measurements. Pressing the HOLD
key will freeze the reading on the display. Calibration is per-
formed using the two trimmers on the front panel. HI 8915
comes supplied with: HI 1230B combination, double-junction,
gel pH electrode, HI 7669AW temperature probe, a 9V battery
and a calibration screwdriver.
• HI 9214 is a compact microprocessor-based pH/°C meter. The
electrode has a built-in temperature sensor for quick and accurate
temperature measurements and temperature compensation. The
meter has three memorized buffer values (pH 4.01, 7.01, and
10.01) and automatic buffer recognition to avoid errors during
calibration. HI 9214 comes supplied with: HI 1217S screw-type
combination gel pH/°C electrode, a 9V battery and HI 710003
soft carrying case.
• HI 931000 is a compact, microprocessor-based pH/°C meter
with a 4-in-1 pH electrode (pH/°C electrode with built-in tem-
perature sensor and signal amplifier). Optional shockproof
rubberboots are also available to prolong the life of the meter
and to prevent damage (see page 51). HI 931000 comes
supplied with: HI 1217D combination gel pH/°C electrode, with a
built-in temperature sensor and signal amplifier, a 9V battery
and HI 710004 soft carrying case.
• HI 9622 is a portable microprocessor-based pH/mV/°C meter
which meets the GLP (Good Laboratory Practice) requirements
and memorizes the last calibration date. The meter has three
memorized buffer values: pH 4.01, 7.01 and 10.01. The meter
can also be used for ISE and ORP measurements with automatic
range switching when readings exceed ±399.9 mV. HI 9622
comes supplied with: HI 1230B combination, double-junction, gel
pH electrode, HI 7669/2W temperature probe and a 9V battery.
