CHAPTER 1

INTRODUCTION

verest Interscience, Inc., offers the most sophisticated non-contact infrared
thermometers on the market today. The new AGRI-THERM II Handheld

E

thirty-eight years of research and development by our founder and President. These are
revolutionary handheld infrared thermometers, as they can be focused in the field or lab
using our Vario-Zooom (Patent Pending) variable focusing system. And they incorporate
our TTL (Through-The-Lens) Intra-Optical Light Sighting System (Patent No.
4,494,881).

An infrared thermometer measures the temperature of a target surface by focusing a spot
on the target through an optical field-of-view (telescope) onto a temperature-sensitive
detector. Infrared radiation is transmitted through the optics and impinges on the infrared
detector, heating it slightly.

A major shortcoming of infrared thermometers is that the infrared “light” (radiation) is
invisible to the human eye. Therefore, the position and physical characteristics of the
spot being measured, such as its location, shape, size, surface texture, etc., cannot be
ascertained by the operator. It is very important for the operator to know where all parts
of the target spot are located, because, if any part of the spot is off the edge of the target
surface, serious reading errors will occur. The Everest TTL (Through-The-Lens) Intra­Optical Light Sighting System (Patent No. 4,494,881) solves this problem as explained in
Chapter 3 of this manual.

The Model 6110.4ZL Portable Infrared Thermometers takes readings in a fraction of a
second over a temperature range of -40ºC to 100ºC or -40 to 200ºF with 0.1° resolution.

The AGRI-THERM II Differential (Patent No. 4,301,682) Handheld Infrared
Thermometer is light-weight, weighing less than two pounds. It is powered by
rechargeable nickel-cadmium batteries and has a standard output of 10.0mV/ºC or °F.

We are pleased that you chose an Everest infrared surface thermometer. We are positive
that you will be pleased with the versatility, dependability and reliability that have been
engineered into these highly sophisticated infrared thermometers.

If you have questions about a particular application, or if you have difficulty with any
aspect of the operation or functioning of your new infrared thermometer, please don’t
hesitate to contact us. Our telephone numbers and addresses are listed on the front cover
of this manual.

Differential Infrared Thermometer (Model 6110.4ZL) is the culmination of over

plug on the end of the six-foot lead of the supplied battery charger into the Rear Panel
Jack of the infrared thermometer labeled “BATT.” The “BATT” jack can be found on
the left hand side of the Rear Panel. Then, plug the AC adaptor into 90-250 Volt AC
50/60 Hz power source.

Allow ten (10) hours for a complete charge; partial charges are okay. When charging is
complete, unplug the AC adaptor from the outlet and then remove the plug from the
instrument.

he abbreviations on the Rear Panel of the AGRI-THERM II stand for the
following:

9 SEL = Select: IR, DIFF or AMB

9 IR = Infrared Surface Temperature Reading

This is the current infrared surface temperature reading of the target
that the instrument is focused on.

9 DIFF = Temperature Differential

This is the Difference between the Dry Bulb Ambient Air Temperature
and the Temperature of the target.

9 AMB = Dry Bulb Ambient Air Temperature

This is the temperature of the ambient air surrounding the Infrared
Thermometer.

9 PWR = Power: On/Off

9 LITE = TTL Intra-Optical Light Sighting: On/Off

9 DATA = Plug for outputting the data selected by “SEL” at the rate of

10mV/º.

9 BATT = Place to plug in battery charger.

THROUGH-THE-LENS (TTL) INTRA-OPTICAL LIGHT

SIGHTING (Patent No. 4,494,881)

3.1 TTL SIGHTING

ith the Everest Through-The-Lens (TTL) Intra-Optical Light Sighting System
(Patent No. 4,494,881), an illuminated image of the infrared detector is

W

projected directly through the infrared optics of the infrared temperature
sensor, illuminating the exact area where a temperature measurement is being
taken. Because this light shares the internal optical path, it can never be knocked
out of alignment. It will always illuminate the area where the infrared/visible
optics are focused.

3.2 FOCUSING WITH THE VARIO-ZOOOM

n order to focus on a smaller or larger area, the front of the Vario-Zooom (Patent
Pending) infrared thermometer need only be pushed in or out until the target is

I

completely illuminated. Simply point the instrument at a target in subdued ambient

light and push the front optics in or pull it out in order to focus the infrared
thermometer to display the field-of-view (FOV) of the instrument.

A picture of the Front Optics of the AGR-THERM II Infrared Thermometer with the
antenna extended for Dry Bulb Ambient Air Temperatures is shown below:

To focus an instrument that will be used in the field or out-of-doors, first set the
instrument up in subdued lighting in a laboratory. There you will be able to see the light
being emitted by the Light Emitting Diode (LED) and determine the distance to spot size
ratio. Then, when you are in the field, you can determine the area being measured by
knowing that the ratio of the distance to spot size will remain constant as it was in the lab.
