DTW series high temperature salt tank is a new product developed according to the user's requirements for temperature element verifification. It has the same structure as the standard oil tank used in the laboratory. It has an independent heating system, a stirring system and an original Japanese version up to 0.1 The imported temperature control system provides users with a precise heat source. It has a wide temperature range, high temperature control accuracy throughout the temperature range, liquid medium pressureless, non-toxic, non-corrosive, and the detection and insertion hole diameter can be replaced by the old heat pipes. It is suitable for high-precision detection of temperature components such as thermocouples and thermal resistances.
