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.
