Usb Room Thermometer Review
I had no unreasonable expectations about Usb Room Thermometer, because I knew it to be thermally coupled to the (hot) computer over the fairly short USB extension, but this device far below even my expectations rather low. In short, it has three flaws I discovered after a brief examination:
1) If you tried to measure just to a temperature above 37 C, they will get "glued" at 37,00 C, which is a very suspicious property. Only when the temperature is above 39 C, it will get to "glue", and produce a higher temperature reading. The curve presented by the nice software bundled with the device that "makes mistakes" on the hand.
2) It significantly Hysteresis: The temperature reading in the same compartment was dependent on the starting temperature of the device (if you're already pre-heat or cool it, the final value is different) after a reasonable period of equilibrium. The hysteresis is more than 2.0 C, which is unacceptable.
3) It significantly overestimates the ambient temperature, probably due to the thermal coupling with the computer.
On the positive side I can only say that I love her with the software bundled with curve-plot, etc. I only wish that the thermometer itself was accurate to at least 1.0 F (0.56 C), that's all I needed.
