1st, application
WRN-230D, the WRN-430D multi-spot thermometer (multi-spot thermal resistance, multi-spot thermo-element) is suitable in produces the scene existence gradient of temperature not to be remarkable, must simultaneously survey many positions or position many place surveys. As the survey temperature's sensor, usually the multi-spot thermometer and the demonstration accommodometer, the recording instrument and the electronic regulator and so on necessary use, may in the direct measurement each kind of production process from 0¡æ~1300¡æ the scope liquid, the steam and the gas medium as well as the solid surface temperature. Widely applies in the big chemical fertilizer synthetic tower, saves installments and so on storage tank.
