I have used those laser thermometers on the oil rigs lots to check the temp of fluids. They are usually fairly accurate, but I wouldn't use them as a calibration tool.

It works great if you use a human designed thermometer to measure your body temp, check its accuracy, and then use that thermometer in the tank beside your aquarium thermometer. I have done this, and I find both of my digital TDS meters (one Hanna, one HM) are both accurate for temperature. Using that I have calibrated some glass aquarium thermometers that stay in the tank and sump permanently. Both the glass thermometers read 2 degrees too high.
