Muffle Furnace – Digital Computerised
4.75 out of 5

Presto’s Industrial Lab Muffle Furnace – Digital Computerised is specially designed and manufactured for the developing fields of agricultural, medical research industrial, metal treatment, ash determination and wool industries. The device evaluates the ash percentage of a test sample that provides vital information on properties of the material. The device has an elegant design and is convenient to install. The instrument can be used for various applications for example, for mold heating and organic & inorganic tests. The thermal-shielded furnace is cost-effective and energy saving.

The equipment calculates the ash percentage same as the index of added mineral loading. The test is performed by weighing the specimen and then burnt. The burnt sample is calculated easily. The test specimen is torn into small pieces and then placed again to take the weight. The accurate test result can be obtained by performing three tests by reporting minimum, maximum, and average weight.
