The Cooper-Atkins 54011-K Thermocouple Pipe Strap Probe is designed to measure large diameter pipe surface temperatures that standard pipe clamp probes may not fit around. The temperature of a pipe can be read immediately when the probe is plugged into any Type K Thermocouple Instrument, then fastened around the desired pipe. Easy to install, fits pipes up to 3.3”(84 mm) in diameter. Special strap-hook design allows you to quickly secure the probe to the pipe and obtain the most accurate reading.  Use this probe with your own type K thermometer or select from one here.
