Profile: U-Therm International (H.K.) Limited is a manufacturer of coal testing instruments. We manufacture bomb calorimeters, sulfur analyzers, proximate analyzers, ash constituent analyzers, muffle furnaces, hydrocarbon testers, chlorine meters, moisture analyzers, ash fusibility testers, and synthesized instruments. YX-ZR/Q automatic calorimeter is widely used in various industries including electrical power, coal, paper making, petrochemical, cement, farming, & medical research, to measure the caloric value of combustible materials. With the semi-conductor water refrigeration system, the instrument can automatically determine the refrigerating capacity, and balance the circulation system according to the caloric value of the previous time. Thus the water temperature can be kept constant, and the influence of environment can be greatly reduced. It is equipped with the latest oxygen bomb, auto oxygen filling facility, and auto elevating system. All the processes in the experiment are automatic; there is no need to fill oxygen, relief air, measure water, and adjust water temperature. So the workload is greatly reduced. Muffle furnaces are used in electrical power, coal, commerce inspection, environment protection, metallurgy, paper making, petrochemical, earth probe and research institute or quality inspection organization, to test the ash or volatile constituent content in coal.
