80PK-8
Type K Thermocouple Pipe Clamp Temperature Probe
Instruction Sheet
Introduction
XWWarning
To avoid electric shock, do not
use this probe when voltages
exceeding 24 V ac or 60 V dc are
present. The probe is electrically
connected to the output terminals.
The 80PK-8 Type K Thermocouple Pipe Clamp
Temperature Probe (Figure 1) is designed to reliably
measure the temperature of pipes ¼-inch (6 mm) to 1
3/8-inch (35 mm) in diameter, at temperatures
between -29 °C and 149 °C (-20 °F and 300 °F),
while retaining a long service life.
