ZDHW-6 microcomputer fully automatic calorimeter

Adopting standards:

GB/T213-2008 "Method for determination of calorific value of coal", GB/T483-2007 "General determination of test methods for coal analysis", GB/T384-1981 "Method for determination of calorific value of petroleum products", GB/T30727-2014 "Method for determination of calorific value of solid biomass fuels" GB/T14402-2007Combustion performance of building materials and products - Determination of calorific value of combustion》JC/T1005-2006 "Method for determination of calorific value of cement black raw materials"ASTM D5865-13 "Standard Test Method for Gross Heating Value of Coal and Coke", ISO1928-2009 "Solid Mineral Fuel - Determination of Total Value and Calculation of Net Heating Value by Oxygen Bomb Calorimeter" CEN/TS 14918Method for determining the calorific value of solid biofuels》The BS SN 15400-2011Solid Recycling Fuel - Heat Generation Test》The IS：1350-1970Methods for determination of coal and coke》.

Scope of application:

It is mainly suitable for measuring the calorific value of solid or liquid combustible substances such as coal, petroleum, chemical, food, wood, etc. in industries or departments such as electricity, coal, papermaking, petrochemicals, cement, agriculture and animal husbandry, medicine, scientific research, and teaching.

Performance characteristics:

The ZDHW-6 microcomputer fully automatic calorimeter adopts industrial serial port display technology to achieve intuitive display of experiments and capacitive screen touch control equipment.

■ Unique ultra-high bit analog-to-digital conversion technology: This product uses a 24 bit analog-to-digital converter for higher accuracy and precision.

■ AdoptingaccurateCompressor refrigeration technology adopts domestic "circulating water cooling technology" to quickly return the outer cylinder water temperature to near the starting value, reduce the cooling correction factor, and make the measurement results more accurate.

Internal device: Imported mixing motors are used internally to drive sheet-like blades for constant temperature mixing, and submersible electric mixing is used for the mixing of the outer cylinder, making the mixing more uniform and convenient. The instrument adopts a fused cotton thread ignition method.

High degree of automation: By using a water quantification device and combining it with an automatic water circulation system, the water volume in the inner bucket can be accurately quantified without the need for manual weighing and adjusting of water temperature. This avoids errors caused by human factors during the operation process, reduces the labor intensity of operators, shortens testing time, and improves work efficiency.
