Take temps in-close or at-range. Point the
laser for 8:1 IR (infrared) temperatures or
push the rod through ducts for dry bulb air
temperatures. T1-T2 mode works across both
IR and Rod modes.

Description

!

Use the SPK3 IR and Rod Thermometer to quickly mea-

sure surface temperatures or to check the dry bulb inside
duct work. It has an 8:1 eld of view which means at 16 feet
away, you are seeing the average temperature of a 2 foot
circle. The backlit display automatically ips in ROD mode
for hanging on duct walls.

WARNING

Never point the laser towards the eyes as permanent
eye damage may occur.
Use extreme caution when using the laser.
Keep out of the reach of children.

Be careful around mirror surfaces since mirrors can reect the
laser. Looking into the reected laser is just as damaging as looking

directly at the laser.

Operation

Press MEAS/HOLD to power-on into IR mode.
Press ROD to ip the display and view probe temp.
There is no OFF button. Your SPK3 will turn o auto­matically after 3 minutes (15 min in T1-T2 mode.)

IR (Infrared) Mode

1. Hold the MEAS button while aiming the sensor
at the surface you want to measure.

2. The surface temperature will automatically be
held on the display when MEAS is released.

ROD (Thermistor) Mode

1. Display ips so it can be seen when hanging.

2. Press MEAS/HOLD to freeze the display.

T1-T2 (Works between both IR and ROD)

1. Press T1-T2 to view T1.

Note: You must hold MEAS if in IR mode.

2. Press T1-T2 to lock in T1 and switch to T2.

3. Press T1-T2 to lock in T2 and view T1-T2.

4. Hold T1-T2 to exit.

Units

Hold T1-T2 and M/m to toggle °F and °C.

Max/min

1. Press M/m to begin recording maximum and
minimum values.

2. Press M/m to cycle through maximum, minimum,
and real-time (MAXMIN blinks) values.

3. Hold M/m to clear recorded values and exit.

Battery Replacement

When your meter’s battery is low, the laser and LCD
brightness will dim. “Lob” will display and meter will power
o. Open the bottom battery cover with a mini screwdriver

and replace the 2 AAA batteries.

Infrared Test Tips

The infrared sensor is very sensitive to ambient temperature
changes. For best accuracy, do not quickly go from a hot truck to a
cold basement. It also helps to keep hands away from sensor.
When something is hot, it radiates infrared (IR) energy. The SPK3
collects infrared energy from a circular viewing area and measures
the total amount of energy collected. The SPK3 converts the total
energy measured to a temperature. Distance doesn’t matter because
the further you go from the target, the increase in area “seen” by
the sensor exactly balances the loss of energy collected from a
given area. If you want to get the temperature of something small,
such as a pipe, you must get close enough so the pipe takes up the
whole viewing area circle. Otherwise the pipe and the background
temperatures will be averaged into the reading. Though for best
results, it’s best to measure from at least 1 foot (30cm) of your target.
The accuracy of many infrared temperature measuring systems
is adversely aected by ambient temperature. You need to be aware
that if the target surface is reective enough, it may reect infrared
from other objects. For example, if you take a reading of a shiny
metal surface, the infrared energy of your face may reect enough
energy o the surface to aect the reading.
“Emissivity” of the target surface also aects the temperature
reading. For a given temperature, the higher the emissivity, the
higher the reading. The lower the emissivity, the lower the reading.
Emissivity of a surface indicates how easy it is for the infrared to get
out. Emissivity for a dull, black surface is high (nearly 100%) so it’s
easy for the infrared to get out. Emissivity for a shiny surface can
be much lower. If the emissivity is low, the measured temperature
will be lower than actual. For relative readings of the same kind of
surface, this isn’t a problem. For some applications, it may be neces­sary to spray dull, black paint on the target to insure a more accurate
reading. For best accuracy use contact sensors (thermocouples,
thermistors, etc.) anytime you take a temperature measurement.
Infrared instruments should only be used when you aren’t able to
touch the surface to be measured.
