Celsius fast response sensor

Greetings all…does this sensor only work in fluids, or can it record accurate temps in air?

Hi @FairweatherIT,

The Celsius temperature sensor was nominally design for use in water, but there is nothing about it that would prevent its use in air. Note that the reaction time will be longer in air however.


Thanks Adam…going to be dropping one down a flooded mine shaft for some inspection work…

Hi Ian
I did some testing with the senor in air and it appears the alloy cage can maintain the heat around the sensor and hence the readings can be a bit off. For example if you hold the sensor in your hand it takes a long time for the alloy cage to adjust to the ambient temperature (I measured around 20 minutes). So personally I would only stick to water.

Interesting, thanks Connon!
