GENERAL DESCRIPTION

HI 93510, HI 93510N, HI 93512 and HI 93522 are powerful and
flexible thermistor thermometers, which have been designed using the
latest microprocessor technology to provide reliable and accurate
measurements.

Standard features include waterproof casing, dual-level LCD, low
battery detection, long battery life and two-year warranty.

HI 93510 has been designed for laboratory and field use, while HI
93510N is suitable for high accuracy (meter and probe can be

calibrated in an ice bath at 0°C) or dimly lit areas (the backlight
feature can be easily activated through the keyboard).

HI 93512 is a two-channel thermometer, ideal for monitoring two
samples at once, while HI 93522 offers all the features of HI 93512
and more: calibration of meter and probe at 0°C, backlight, user­selectable auto-off time period, and capability to store and recall a
reading.

OPERATIONAL GUIDE

To switch the instrument ON, press the ON/OFF key.
The thermometer will carry out a self diagnostic test routine, the LCD
will show all segments for a few seconds (or as long as ON/OFF is
held), followed by the percentage indication of the remaining battery
life.

Note: Although the display is frozen, internally the meter continues

measuring and updating Hi/Lo and relative values.

In HI 93522 only, the held value is also stored in non-volatile
memory and can be recalled by pressing (ALT+) MR key. While the
MR key is held, the "HOLD" tag lights up and the meter displays the
stored value; when the MR key is released, after 1 second the meter
returns to normal measurement mode.

The thermometer then enters normal measurement mode.
If a temperature probe is plugged in, the meter displays the
measured temperature.
If no probe is plugged in, or if the reading is
over-range, the display shows flashing dashes.
If a measurement is slightly over the range
of the meter specifications, the display will
flash the closest full-scale value.
To switch the meter OFF, press the ON/OFF key.

°C/°F SELECTION

Measurements can be displayed in either degrees Celsius or Fahren­heit. The meter is factory set to °C scale; to change the scale, press
°C/°F key or (ALT+) °C/°F keys,

HI 93510 / 510N

HI 93522

or set the switch located in the battery compartment (HI 93512 only, see
figure on page 10).

HOLD and MR FUNCTIONS

The HOLD function is activated by pressing the HOLD key.
The measured temperature is held on the
display until HOLD is pressed again. The
"HOLD" tag blinks on the display while in
HOLD mode.

HIGH/LOW TEMPERATURES

The maximum and minimum tempera­tures are continuously monitored and
displayed on the lower portion of the LCD.

Note: When the reading goes over-range or the probe is removed,

the Hi and Lo values display dashes until cleared.

CLEAR FUNCTION

Upon pressing the CLR key, the High/Low values may be cleared at
any time during measurement and the current reading is assigned to
the highest and lowest temperature values for the displayed channel
only.

AUTO SHUT-OFF (HI 93510 and HI 93522)

To save battery life, the HI 93510 and HI 93522 models are
provided with an auto-off feature, which switches the instrument off
after a certain period of nonuse.
The auto-off delay time can be changed by the user (8 minutes, 60
minutes, or disabled).
To access this feature, the HI 93510 is provided with an internal
button located in the battery compartment (see figure on page 10).
Unscrew the 4 screws on the back of the meter and select the desired
auto-off time period by pressing the button and viewing the value on
the LCD. Reattach the back making sure that the gasket is in place
and tighten the 4 screws to ensure a watertight seal.

HI 93522 allows the user to select the auto-off time period through
the keyboard; press (ALT+) AOFF to enter the mode, then set the
desired auto shut-off interval (8 min, 60 min, or disabled) with the
ALT key; release all buttons, wait a few seconds and the meter will
return to normal measurement mode.

2-CHANNEL MODELS (HI 93512 and HI 93522)

HI 93512 and HI 93522 models can monitor two samples through
two independent temperature channels (probes).

The display will show the actual, Hi and Lo (or T1 and T2) values of
the selected channel (T1, T2 or T1-T2). The corresponding tag will
light up to inform the user.

To select the desired channel, use the T1/T2 key.

BACKLIGHT FEATURE (HI 93510N and HI 93522)

HI 93510N and HI 93522 models are provided with a Backlight
feature, which can be easily activated through the keyboard by

pressing the BL key or (ALT+)BL keys.

HI 93510N

HI 93522

Note: The backlight automatically shuts off after approximately 1

minute with no buttons pressed.

BATTERY COMPARTMENT

The 2-channel models are also provided with the DISP function, which
allows the user to select the information to be displayed.

• While in T1 or T2, pressing DISP will switch the display between
standard and relative measurement modes.
In the standard mode, the main body of the LCD shows the
current temperature while the lower portion displays the Hi/Lo
limits for that channel.
When the meter enters relative mode, the current temperature for
that channel is set as the reference temperature. Pressing CLR will
also set the reference to the current temperature.

In relative mode, the main body of the LCD shows the difference
from the reference temperature. The lower portion displays the
current temperature for the selected channel.

• While in T1-T2, pressing DISP will switch between 3 displays:

Note: Pressing T1/T2 to change the channel will not alter the

information chosen to be displayed for each channel (DISP).

Note: Relative mode can not be entered if dashes are shown in the

main portion of the LCD.

BATTERY REPLACEMENTUSER CALIBRATION

The HI 93510N and HI 93522 models can be calibrated at 0°C by
using an ice bath.

• Prepare an ice bath with approximately equal volumes of distilled
water and chopped ice made from distilled water.

• Immerse the temperature probe in the center of the ice bath,
taking care not to touch the ice with the probe tip.

• Ensure that the meter is measuring a temperature within ±3°C.

• To enter the Calibration mode, press and hold the CAL button for
about 5 seconds.

• The CAL tag turns on to indicate that
the Calibration mode has been entered.

Note: If the measurement is outside the

±3°C window, the meter does not
enter Calibration mode.

• When the meter reaches the stability condition, which is detected
when the measurement remains within ±0.2°C for 5 seconds, the
calibration is accepted and the reading becomes 0°C (32°F).

• The meter then automatically returns to normal mode.

Note: To exit the Calibration mode at any time, press the CAL key.
Note: User calibration cannot be entered in relative or in T1-T2 mode.
Note: User calibration is only performed on the current channel

displayed (T1 or T2).

FACTORY RECALIBRATION

When the battery level is below 10%, a warning
symbol will blink on the LCD to indicate a low
battery condition.
If the battery level is low enough to cause erroneous readings, the
Battery Error Prevention System (BEPS) turns the meter off.
Immediately replace the batteries with new ones.
The batteries are accessed by separating the front and the back
halves of the meter: unscrew the 4 screws on the back of the meter
and carefully replace the three batteries located in the battery
compartment, while paying attention to their polarity. Reattach the
back making sure that the gasket is in place and tighten the 4
screws to ensure a watertight seal.
Battery replacement must only take place in a non-hazardous area
using 1.5V AA (IEC LR6) alkaline batteries.

All Hanna thermometers have been accurately pre-calibrated at the
factory. It is generally recommended to have all thermometers recali­brated at least once a year. For an accurate recalibration, contact your
nearest Hanna Customer Service Center.
Hanna Accuracy Test Plugs provide a quick and easy way to check the
meter's accuracy by simply connecting these Test Plugs to the probe
connector of the meter. If the reading differs by more than ±0.4°C
(±0.8°F) from the Test Plug value, the meter is due for recalibration.

Choose the right Test Plug to suit your needs:

HI 762-18C Calibration test key, -18.0°C
HI 762000C Calibration test key, 0.0°C
HI 762070C Calibration test key, 70.0°C
HI 762-004F Calibration test key, -0.4°F
HI 762032F Calibration test key, 32.0°F
HI 762158F Calibration test key, 158.0°F

Recommendations for Users

Before using these products, make sure that they are entirely suitable for the
