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.
