PRELIMINARY EXAMINATION

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, immedi­ately notify your Dealer.

Note: Conserve all packing material until the

instrument has been observed to func­tion correctly because all defective
items must be returned to the Dealer
in their original packing.

GENERAL DESCRIPTION

HI 8666 is a 2-wire, 4 to 20 mA relative

humidity and temperature transmitter. The
instrument transmits electrically isolated out­puts that are linear and proportional to RH%
and °C. It can be surface or panel mounted,
and used with a detachable connector. The
power must be supplied from an external
source from 12V to 24V. See the diagrams
on pages 4-6 of this instruction manual for
connections from the transmitter to other
equipment, such as recorder.

Note: After 30 minutes of measurements over

90% RH, the probe sensors could ex­perience secondary absorption, lead­ing to approximately +6% RH satura­tion. This means that the readings will
be inaccurate. To restore the probe to
a normal condition, place the probe
into the LiCl well of HI 7102 for 24
hours (see page 9).

CALIBRATION CHECKING PROCEDURE

All Hanna relative humidity transmitters have
been precalibrated at the factory.
Hanna Instruments uses state-of-the-art ther­mal humidity chambers for this purpose.

It is generally recommended to have all RH
transmitter recalibrated at least once a year.
For an accurate annual recalibration, contact
your nearest Hanna Service Center.

You can also check the status of your HI 8666
by using the Hanna mini-calibration cham­bers HI 7102.
The kit includes two thermally
isolated chambers, each one
equipped with a threaded cap

saturated salts to produce a
known RH value.

This calibration checking procedure is written
to verify that the meter still meets the electri­cal calibration specifications of the factory.

PREPARING THE CALIBRATION
SOLUTIONS

• Pour approximately 26 cc
of distilled water into a
glass container.

• Immerse this container
into a bath of ice and wa­ter and shake briefly.

• Slowly add the contents
of a HI 7111 bottle con­taining LiCl into the glass
container while continuing
to shake.

• When the salt has dis­solved completely, add all

l

Li C

the content of the second
bottle of HI 7111.

• Allow the solution obtained
to cool, and then pour it
into the chamber marked
"RH 11.1%", making sure
that no residue remains on
the walls of the glass con­tainer.

• Seal the chamber well when not in use,
as the LiCl solution is extremely hygro­scopic and tends to capture the humidity
present in the air causing the solution to
expand in volume and to overflow from
the container.

• Add all the content of the

shaking the container to
avoid the formation of

stabilization.

• Bring the calibration kit to a temperature
of approximately 20°C.

• Remove the sintered
cap from the probe of
HI 8666.

• Connect the unit to a 12 to 24VDC power
supply and hook up a multimeter (range
of 20mA) in series with the circuit.

• Remove the cap from the
"RH 11.1%" chamber con­taining the LiCl solution and
insert the HI 8666 paying at­tention not to dip it into the
liquid.

• Wait for the measurement
to stabilize (this takes ap­proximately 4 hours).

• Look at the multimeter display: the read­ing should be 5.78 mA, representing the
theoretical chamber value of 11.1% RH.

All RH to mA conversions can be made
with the tables provided (see page 12).

• Remove the HI 8666 from the chamber
and tightly seal the chamber containing
the LiCl solution.

• Remove the cap from the
"RH 75.4%" chamber con­taining the NaCl solution and
insert the HI 8666.

• Insert the probe in the "RH 75.4%" cham­ber, the multimeter reading should be 16.06

• The relative humidity calibration checking
procedure is complete. If the theoretical
values are not within ±5%, contact your
dealer or your closest Hanna Service Cen­ter for a fast and accurate recalibration.

Spare saturation salts are also available:

HI 7111/P (LiCl) for low range humidity, and
HI 7121/P (NaCl) for high range humidity.

CHECKING THE TEMPERATURE
CALIBRATION

• Remove the sin­tered cap from the
probe of HI 8666.

• Connect the unit to a 12 to 24VDC power
supply and hook up a multimeter (range
of 20mA) in series with the circuit.

• Place the HI 8666 into a stable tempera­ture environment of 25°C, preferably a
temperature chamber, and wait for the
temperature to stabilize.

• Using a NIST certified thermometer as a
reference, e.g. ChecktempC/N, verify that
the ammeter reading is matching the tem­perature, e.g. 13.00 mA for 25°C.

mA

All temperature to mA conversions can
be made with the tables provided (see
page 16).

• Recheck the temperature at both 10°C
(10.00 mA) and 40°C (16.00 mA): they
should both be within ±1%.

If either setting is out of range, the unit
must be repaired or recalibrated electri­cally. Contact your dealer or your closest
Hanna Service Center.
