| TITLE: | Experiment #7 | OBJECTIVE(S): | Test the new "German" digital thermometer, and determine if boiling water does in fact measure 100*C.
(All the instructions are written in German. I don't know how to turn it off unless I remove the battery.) |
GO/NO-GO: | GO (Successful test, however the thermometer is NOT 100% accurate.) | SUMMARY: | Thermometer does NOT measure 100*C when immersed in boiling water. | NEXT ATTEMPT: | n/a |
This experiment has determined this thermometer does NOT measure boiling water as 100*C.

WARNING! WARNING! WARNING!
See "Experiment #8" This thermometer demonstrated itself to be INaccurate! We noted the "overflow" water was measuring 72*C yet it was cool to the touch! 70-75*C is 70% to 75% of the temperature of boiling water! Fortunately our Mystery State Worker pointed out this point, and there was no way it should feel "cool" to the touch! (Incidentally, 212*F times 70% = 148.4*F) |
Boiling water on the stove top. This probe has a "clip" so I was able to suspend it above the bottom of the kettle. |
The thermometer quickly rises to 98*C... (The LEFT-HAND temp. is what the probe reads. The RIGHT-HAND is the "Alarm" temp.) |
Temperature stabilizes at 99*C with the end of the probe in submerged in boiling water. Careful! It's hot! |
| 98.0*C equals 208.4*F | 99.0*C equals 210.2*F |
