Does NCD supply a temperature sensor that can go down to -80C as part of an assembled unit or a module?
the max it can do is -40’C
will it be possible to install the sensor box in a area where temp is above -40’C ?
if it is than you might look into RTD probes ( PT100)
if you still not getting the right idea then you can contact ubibot.io. They will provide you complete setup…
