I just purchased a Fluke 561 IR Thermometer with a direct reading probe.
I have found some interesting differences in the temperature reading with the Direct Reading Probe. If I use the probe and have it directly in the stream of hot water coming from my faucet it reads 122 degrees F. If I hold the probe against the faucet pipe it reads 118 degrees F. Could there be a 4 degree difference between the hot water stream and the faucet pipe. Would the pipe insulate the hot water by 4 degrees. Maybe some one out there could explain the differences.
