Product Description
The machine is in accordance with GB/T384 "calorific value of petroleum products" standard, GB/ t213-2008 "requirements for calorific value of coal", GB/T 5186-1985 "calorific value of biomass fuel test method", GB/T 14402-2007 "determination of combustion performance and calorific value of building materials and products". Designed and manufactured for the determination of the calorific value of non-water-containing petroleum products (gasoline, jet fuel, diesel and fuel oil, etc.) and combustible substances such as coal, coke and paraffin.
Advanced electronic refrigeration technology, completely unaffected by environmental temperature changes, to ensure that the temperature difference between the inside and outside cylinder of the instrument meets the national standards. Can work continuously for long hours. 7. 5-inch touch LCD screen with advanced American technology.
Stainless steel vacuum inner cylinder. The stirring system adopts the original motor imported from Germany.
Fast test speed, test cycle ≤8min(fast method) ≤15min.
The product has good performance and reliability even in harsh environments.
Compact structure, beautiful shape, easy installation and maintenance, low failure rate.
Compact size, a large number of mold manufacturing, high precision.
The repeatability and reproducibility of calorific value test are better than national standard.
High degree of automation, automatic use of the built-in tank water volume, automatic control of the temperature difference between the inside and outside barrels of the instrument, automatic completion of the whole process of the test.
Technical parameters of microcomputer automatic calorimeter:
Temperature measurement range :0-40ºC (change of room temperature should be ≤1ºC for each measurement) relative humidity ≤85%
Precision: 0.1% or less
Resolution: 0.0001 ºC
Precision: 0.1% or less
