The Fluke 80TK is a thermocouple converter for use with any K-type thermocouple and a digital multimeter. The 80TK accepts the output of any K-type thermocouple and converts it to 1 millivolt per degree (Celsius or Fahrenheit).


Measurement Range: -50 to 1000 degrees Celsius
-58 to 1832 degrees Fahrenheit
2000 count display: 0.1° C/F in 200 mV range
1.0° C/F in 2V range
3200 count display: 0.1 C/F in 300 mV range
1.0 C/F in 3V range
4000 count display:  0.1° C/F in 400mV range
1.0° C/F in 4V range
Maximum Voltage 
at Thermocouple Input:
60V DC, 24V AC
RF Field: Exposure to an RF field interferes significantly with
this moduleTs capacity to accurately measure temperature with
thermocouples. The interference is temporary and the module
suffers no harm when exposed to an RF field of 3 V/m.
Accurate temperature measurement capability is completely
restored when the module is removed from the RF field.
Common sources of RF fields are handheld 2-way radios and
cellular telephones. If such a source is suspected of interfering
with this module, either turn off the transmitter or increase the
separation between the transmitter and the module.

Temperature Coefficient: * 0°C to 18°C and 28°C to 50°C ambient, multiply the basicaccuracy specification by 0.1 for each degree above 28 orbelow 18.
For accuracy enhancement between 351°C to 500°C,subtract 3 degrees from the reading. The accuracy is now0.75% ± 2°C.
* For accuracy enhancement between 663°F and 932°F,subtract 5.4 degrees from the reading. The accuracy is now0.75% ± 3.6°F.

The basic accuracy specification does not include the error of the probe or the DMM. Please refer to the probe accuracy specification for additional details.
