Measuring Solutions for Your Application
Thermocouple Meters
Instruments amplify, linearize, and
display the millivolt signal generated
by the two dissimilar wires of the
thermocouple probe. The signal is
proportional to the temperature gradient
between the measuring and reference
junctions. Oakton offers many low-cost,
fast-response probes in a wide variety of
designs. Handheld probes are ideal for
inspection and maintenance. Many types
of probes can be permanently installed.
Probes resist mechanical shock. Use
probe within 2000 feet of the instrument.
Platinum RTD Meters
These instruments provide excellent
accuracy, stability, and repeatability
over a wide temperature range. Probes
have an element with a characteristic
resistance that increases as the
temperature increases. Three-wire probe
reduces effect of lead-length resistance
on measurements, giving a more precise
indication of temperature.
Thermistor Meters
Thermistors exhibit a greater sensitivity
and accuracy in the biological range—
32 to 212°F (0 to 100°C). Probes encase a
ceramic element that generally decreases
in resistance as the temperature
increases.

Type J, K, and E probes: ±1.8 to 7.9°F or ±0.4%
of reading above 32°F, whichever is greater
Type T probes: ±0.9 to 3.6°F or ±0.4% of reading
above 32°F, whichever is greater
Type R and S probes: ±2.5°F or ±0.25% of reading,
whichever is greater

Temperature Instrument Range Guide
The stated accuracy of any temperature measurement device
is for the “Recommended Temperature Range” only. The
narrow section of the temperature bar represents the widest
range the instrument can be used in. Accuracy in this range
is not guaranteed. Probe damage may occur at the extreme
ends of the temperature range. Temperatures listed below
are approximate.
Infrared Thermometers
Provide fast response for surface
temperatures. Models are available for
both close- and far-range measurements.
