What's the difference between the temperature probes and temperature pucks?
The temperature probes are for closed-environment testing, so are to be used in incubators and transport incubators. The temperature pucks are specifically for radiant warmers. If the temperature probes were used in a radiant warmer, the readings would not be accurate; a vent, breeze, or any air movement would severely affect the temperature readings. The temperature pucks are designed to absorb the heat given from the radiant warmer, so external air movement will not affect their reading.
