Introduction

Introduction

The PosiTector Infrared Thermometer (IRT) is a hand-held,

electronic instrument that measures surface temperature quickly
and accurately. It consists of a body (Standard or Advanced) and
probe (pg. 2).

This Quick Guide summarizes the basic functions of the Gage.

When powered-up, the PosiTector automatically

determines which probe is attached and does a self­check.

To disconnect a probe from a body, slide the plastic
probe connector horizontally (in the direction of the
arrow) away from the body. Reverse these steps to
attach a different probe. It is not necessary to power­down the Gage when switching probes.

The PosiTector gage body accepts a wide variety of probe t

ypes
including magnetic, eddy current and ultrasonic coating thickness,
environmental, surface profile, shore hardness durometer, salt
contamination and ultrasonic wall thickness probes. See

Emissivity refers to a material’s ability to emit infrared energy,
compared to an ideal black surface at the same temperature. The
ratio varies from 0 to 1, and each material has a specific emissivity

associated with it. The PosiTector IRT has built in emissivity

settings for certain materials as well as a user-adjustable
emissivity option (pg. 6).

Most organic and painted surfaces have an emissivity of around

0.95, and are ideal surfaces for accurate infrared temperature
readings. Shiny or reflective surfaces can be difficult to measure
with an infrared thermometer, as they tend to reflect ambient
infrared energy instead of their own. To compensate for this, cover
such surfaces with flat paint or a piece of electrical tape. Allow the
paint or tape to acclimate to the surface’s temperature, and take a
measurement over the paint or tape.

Distance to Spot Ratio (D:S)

Distance to Spot Ratio (D:S)

The distance to spot ratio refers
to the relationship between the
diameter of the area being
measured compared to the
instrument’s distance from the
area. As the distance (D) from
the target increases, the spot
size (S) of the area being
measured by the unit becomes
larger. The D:S ratio of the

PosiTector IRT is 5.7:1. For

example, when the instrument is
100 cm (40 inches) from the
target, the spot size will be about
18 cm (7 inches) in diameter.

below.

Alternatively, use one of the following preset options:

Aluminum (rough) = 0.07 Plastics = 0.94

Zinc (Galvanized) = 0.25 Steel (Oxidized) = 0.95
Concrete = 0.54 Wood = 0.95
Paint = 0.96

NOTE:

Depending on surface treatment, metals such as blasted steel can
have a broad range of emissivity values. Adjusting to a known
temperature (measured by a direct contact surface temperature
probe) on a representative sample will assist in obtaining an
accurate emissivity value.
