Table 3 lists recommended Fluke temperature probes for use with the Thermometer:

Table 3. Recommended Temperature Probes

Probe Usage

80PK-25

The piercing probe is the most versatile option. Good for checking air

temperature in ducts, surface temperature under carpets/pads, liquids,

thermometer wells, vent temperatures, and for penetrating pipe insulation.

80PK-1

The general purpose bead probe is an alternative, for quick, accurate surface

temperatures and air temperatures within ducts, vent temperatures.

80PK-8

Pipe clamp probes (2) are essential for tracking continuously changing

temperature differentials on hydronic tubing and pipe loops, and good for

quick, accurate refrigerant temperatures.

80PK-26

The tapered probe is a good general-purpose gas and surface probe, with a

good length and low mass tip casing for faster reaction to surface and air

temperatures.

80PK-9

The insulation piercing probe provides a sharp tip to pierce pipe insulation

and flat probe tip for good surface thermal contact, air temperatures within

ducts, and vent temperatures.

80PK-11

The Velcro pipe probe is a convenient way to attach a thermocouple to a

pipe while keeping hands free.

HOLD

The display will remain activated for 7 seconds after the trigger is released. HOLD appears in

the upper middle of the display. When the trigger is pulled again, the Thermometer will begin

measuring in the last function selected.

Maintenance

Changing the Battery

To install or change the two AA batteries, open the battery compartment and insert the batteries

as shown in Figure 2.

Cleaning the Lens

Blow off loose particles using clean compressed air. Carefully wipe the surface with a moist

cotton swab. The swab may be moistened with water.

Cleaning the Housing

Use soap and water on a damp sponge or soft cloth.

WCaution

To avoid damaging the Thermometer, do NOT submerge it in water.
