INTRODUCTION

The Fluke 80PK-IR Infrared Thermocouple Probe (the

probe) is a noncontact temperature measurement acces-

sory for use with a digital Type K thermometer. The probe

hasatemperaturerangeof-18°Cto260°C(0°Fto500°F),

with a basic accuracy of 3% of reading, and a Type K

miniature thermocouple connector.

Temperature is measured by pointing the probe at the

surface to be measured and reading the temperature on

the thermometer display.

Distance to Spot Size Ratio

Distance to Spot Size Ratio (or Field of View) refers to the

diameter of the spot that the probe is sensing at a given

distance. The closer you are to the object (or target), the

smallerthearea(orspot)theprobeissensing.Forexample

whentheprobeisheldata200mm(8in.)distancefromthe

target, the spot size is approximately 50 mm (2 in.); at 100

mm(4in.)thespotsizeisapproximately25mm(1in.),and

with the probe held at a 50 mm (2 in.) distance from the

target, the spot size is approximately 13 mm (1/2 in.). Hot

spots can be missed if too large an area is included in the

field of view, so get as close as possible without touching!

(See Figure 2.)

Operational Check

For an operating test of the probe, point it directly at ice

immersed in water (slush). The meter should read, within

specifications limits, 0°C (32°F) (see Accuracy specifica-

tions).

Front-Window Cleaning (as necessary)

1. Blow off loose particles using clean compressed air.

2. Gently brush remaining debris away with a camel hair

brush or cotton swab.

3. Carefully wipe the surface with a moist cotton swab.

The swab may be moistened with water or a water-

based glass cleaner. Allow to air dry. (Do not use

solvents to clean the window.)

WARNING

IF TARGET EMISSIVITY IS LESS THAN 0.95, THE

PROBE CAN INDICATE A TEMPERATURE LOWER

THAN THE ACTUAL TARGET TEMPERATURE.

AVOIDTOUCHINGTHETARGET;THERMALBURNS

COULD RESULT.

CAUTION

• Do not place the probe on or around hot objects

(≥70°C / 158°F). Heat may cause damage to the

probe case.

• If the probe is exposed to significant changes in

ambient temperature (hot to cold or cold to hot),

allow 20 minutes for temperature stabilization

before taking measurements.

• Do not operate the probe near large electrical or

magnetic fields, such as arc welders and induc-

tion heaters. These fields can cause measure-

ment errors.

• Condensation may form on the lens when going

from a cold to hot environment. Wait 10 minutes

forcondensationtodissipate before takingmea-

surements.

• Connectorsmustonlybepluggedintominiature

Type K input jacks of a digital thermometer.

• Donot touch or holdby the front cone.Tempera-

ture readings can be affected by heat from the

hand.

• Equipment use not specified by the manufac-

turer may impair safety.

Emissivity

Allobjectsemitinvisibleinfraredenergy.Thisability,called

emissivity, is based upon the material that the object is

made of and its surface finish. Emissivity values typically

range from 0.10 for a very reflective object to 1.00 for a

black body. The probe senses this energy assuming that

the target has an emissivity value of 0.95. This value is

factorysetintheprobe.Iftheactualtargetemissivityisless

than0.95,theindicatedtemperaturecouldbelessthanthe

actualtargetsurfacetemperature.Tocorrectforthis,safely

coat the target with a substance with emissivity ≥0.95 or

thermally bond a "target" with emissivity ≥0.95 to the

surface to be measured.

Figure 1.

COMPATIBILITY

The probe is compatible with all digital thermometers that

accept standard miniature Type K polarized thermocouple

plugs with flat, in-line blades spaced 7.9 mm (0.312 in.)

center-to-center.

OPERATION

To take a measurement, perform the following steps:

1. PlugtheyellowconnectorintotheminiatureTypeK jack

on the thermometer.

2. Turn on the thermometer.

3. Slide the probe switch to “ON”.

4. Point the tip of the probe at the object to be measured.

5. Read the thermometer display. (Refer to Table 1 for

error conditions.)

NOTE

After10minutesofuse,theprobeautomaticallyshifts

to Sleep mode (the display shows ambient tempera-

ture). Restartthe probeby sliding theswitch to“OFF”

and then to “ON” (see Table 1). Sleep mode extends

batterylife.However, formaximumbattery life,switch

the probe to the “OFF” position.

Measurement Considerations

• For small target surfaces (13 mm (1/2 in.) or less), hold

the probe as close as possible without touching the

surface (no more than 50 mm (2 in.) away).

• Ifthesurfacetobemeasurediscoveredbyfrostorother

SAFETY INFORMATION

The 80PK-IR complies with IEC Publication 1010-1-1990

including Amendment 1, CSA C22.2 No. 231, ANSI/ISA-

S82.01 and .03 Safety Standards.

WARNING

IF TARGET EMISSIVITY IS LESS THAN 0.95, THE

PROBE CAN INDICATE A TEMPERATURE LOWER

THAN THE ACTUAL TARGET TEMPERATURE.

AVOIDTOUCHINGTHETARGET;THERMALBURNS

COULD RESULT.

CAUTION

• Do not place the probe on or around hot objects

(≥70°C / 158°F). Heat may cause damage to the

probe case.

• If the probe is exposed to significant changes in

ambient temperature (hot to cold or cold to hot),

allow 20 minutes for temperature stabilization

before taking measurements.

• Do not operate the probe near large electrical or

magnetic fields, such as arc welders and induc-

tion heaters. These fields can cause measure-

ment errors.

• Condensation may form on the lens when going

from a cold to hot environment. Wait 10 minutes

forcondensationtodissipate before takingmea-

surements.

• Connectorsmustonlybepluggedintominiature

Type K input jacks of a digital thermometer.

• Donot touch or holdby the front cone.Tempera-

ture readings can be affected by heat from the

hand.

• Equipment use not specified by the manufac-

turer may impair safety.

Emissivity

Allobjectsemitinvisibleinfraredenergy.Thisability,called

emissivity, is based upon the material that the object is

made of and its surface finish. Emissivity values typically

range from 0.10 for a very reflective object to 1.00 for a

black body. The probe senses this energy assuming that

the target has an emissivity value of 0.95. This value is

factorysetintheprobe.Iftheactualtargetemissivityisless

than0.95,theindicatedtemperaturecouldbelessthanthe

actualtargetsurfacetemperature.Tocorrectforthis,safely

coat the target with a substance with emissivity ≥0.95 or

thermally bond a "target" with emissivity ≥0.95 to the

surface to be measured.

Figure 1.

COMPATIBILITY

The probe is compatible with all digital thermometers that

accept standard miniature Type K polarized thermocouple

plugs with flat, in-line blades spaced 7.9 mm (0.312 in.)

center-to-center.

OPERATION

To take a measurement, perform the following steps:

1. PlugtheyellowconnectorintotheminiatureTypeK jack

on the thermometer.

2. Turn on the thermometer.

3. Slide the probe switch to “ON”.

4. Point the tip of the probe at the object to be measured.

5. Read the thermometer display. (Refer to Table 1 for

error conditions.)

NOTE

After10minutesofuse,theprobeautomaticallyshifts

to Sleep mode (the display shows ambient tempera-

ture). Restartthe probeby sliding theswitch to“OFF”

and then to “ON” (see Table 1). Sleep mode extends

batterylife.However, formaximumbattery life,switch

the probe to the “OFF” position.

Measurement Considerations

• For small target surfaces (13 mm (1/2 in.) or less), hold

the probe as close as possible without touching the

surface (no more than 50 mm (2 in.) away).

• Ifthesurfacetobemeasurediscoveredbyfrostorother

material, clean it to expose the surface.

• Iftarget emissivityis lessthan 0.95,wait untilthe target

is at a safe temperature, then apply a high emissivity

coating to the surface (such as flat black paint or

masking tape.)

• If the probe seems to be giving incorrect readings,

check the front of the probe. There may be condensa-

tion or debris obstructing the sensor; clean per "Front

Window Cleaning" instructions.

INTRODUCTION

The Fluke 80PK-IR Infrared Thermocouple Probe (the

probe) is a noncontact temperature measurement acces-

sory for use with a digital Type K thermometer. The probe

hasatemperaturerangeof-18°Cto260°C(0°Fto500°F),

with a basic accuracy of 3% of reading, and a Type K

miniature thermocouple connector.

Temperature is measured by pointing the probe at the

surface to be measured and reading the temperature on

the thermometer display.
