Existent Gum Content Tester (Jet Evaporation Method) ASTM D381

Performance Characteristics:

● The main body of the evaporation bath is aluminum.There is a spiral air path and a pressure equalizing chamber in the aluminum bath.The air (air compressor is connected to the inlet of the compressed air purifier through the connecting pipeline. And then from the compressed air purifier outlet is connected to the aluminum bath inlet through the connection line)or steam(electric heating steam generator outlet through the connection line to thee aluminum bath inlet)from the air inlet through the spiral pipe into the pressure chamber,and then evenly from thee aluminum bath central outlet spray to the beaker test;

● There are two holes above the aluminum bath,the front hole is inserted into the thermometer,the back hole is inserted into the thermocouple; 

● Air or steam inlet in the aluminum bath above,equipped with pressure gauge,ventilation should be reached (air is MPa,steam 0.03~0.04MPa),a hand valve can be adjusted; 

● There is a convenient thermometer hoder above the center of the aluminum bath.It can move up and down and rotate 360 degrees,which can easily detect the temperature of each bath hole. 

● The superheater is made of 3mm stainless steel tube.The superheater and evaporation bath areintegrated structure. It is mainly used as compensation when the temperature of aluminum bath fails to meet the standard requirements.
