NHD Refractoriness Tester

　　NHD refractoriness Tester is used to determine refractoriness of refractory materials below 1900℃, which has been developed according to GB/T 7322 and  ISO 528. The tester can be manipulated simply and has excellent performance.

　　Type 02: classic, carbon particle heating, well type structure, artificial judgment;

　　Type 03D: bottom loading, special selection of infrared radiation pyrometer,  simple operation and excellent performance

　　NHD-1800PC and NHD-1809PC has a members of patents,using GM1900 heating elements,full fibre energy-saving lining, high temperature thermocouple, image monitoring the deformation of pyrometric peference cones and test cone , real-time display of parameters recording, automatic test process. The whole machine is easy to operate, energy saving and excellent performance.
