Remove the instrument from the packing material and examine it
carefully to make sure that no damage has occurred during shipment. If noticeable damage is found, notify your Dealer.
Note: Save all packing material until you are sure that the
instrument functions correctly. Any defective items must be
returned in the original packing together with the supplied
accessories.
GENERAL DESCRIPTIONGENERAL DESCRIPTION
GENERAL DESCRIPTION
GENERAL DESCRIPTIONGENERAL DESCRIPTION
HI 8014, HI 8314, HI 8424, HI 8915, HI 931000 and HI 9622
are hand-held pH/mV meters. HI 9214 is a compact stick pH meter
designed to be carried anywhere.
Common features are: interchangeable plastic-body electrodes, simple
controls on the front panel, low battery detector, large easy-to-read
LCD display, simple calibration procedure and lightweight ABS plastic
housing.
• HI 8014 is an affordable portable pH/mV meter ideally suited
for the educational field. The pH or mV ranges are easily selected
with a rotary knob. A °C range is also provided for manual
temperature compensation. HI 8014 comes supplied with: HI 1332B
combination, double-junction, refillable pH electrode and a 9 volt
battery.
• HI 8314 is a pH/mV/°C meter designed for simplicity of use in
taking pH, mV (ORP) and temperature measurements. The pH,
mV and °C ranges are easily selected using a membrane
keyboard on the front panel. Temperature compensation of pH is
automatic when the temperature probe is connected and calibration adjustments are easily made with two trimmers on the front
panel. HI 8314 comes supplied with: HI 1230B combination,
double-junction, gel pH electrode, HI 7669AW temperature probe,
a 9 volt battery and a calibration screwdriver.
• HI 8424 is a portable microprocessor-based pH/mV/°C meter. It
features a user-friendly membrane keyboard, automatic calibration and error codes to guide the user in calibration and
troubleshooting. The meter has three memorized buffer values:
3
pH 4.01, pH 7.01 and pH 10.01. It can also be used for ISE
and ORP measurements with automatic range switching when
readings exceed ±399.9 mV. HI 8424 comes supplied with:
HI 1230B combination, double-junction, gel pH electrode,
H I 7669AW temperature probe and a 9 volt battery.
• HI 8915 is a portable pH/mV/°C meter that combines accurate
pH measurements with a recorder output capability and automatic 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 performed 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 9 volt
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, pH 7.01, pH
10.01) and automatic buffer recognition to avoid errors during
calibration. There are no trimmers making calibration an easy
process, even for nontechnical personnel. HI 9214 comes supplied
with: HI 1217S screw-type combination gel pH/°C electrode, a 9
volt battery and HI 710003 soft carrying case.
• HI 931000 is a compact, microprocessor-based pH/°C meter with
4-in-1 pH electrode (pH/°C electrode with built-in temperature
sensor and signal amplifier). Special shockproof rubberboots are
also available to prolong the life of the meter and to prevent
damage (see page 51). HI 931000 comes sup plied with : HI 1217D
combination gel pH/°C electrode, with a built-in temperature
sensor and signal amplifier, a 9 volt 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, pH 7.01 and pH 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, doublejunction, gel pH electrode, HI 7669/2W temperature probe and
a 9 volt battery.
